Handy-size Global Navigation System Debuts from Sony
TOKYO, JAPAN, 1991 JUNE 10 (NB) -- Sony has developed a portable
device to locate one's position on the globe. Called the Portable
GPS Receiver Pixcess, it weighs only 590 grams (1.3 pounds) and is
small enough to carried around. It measures 10 x 17.5 x 3.9 cm.
It will be sold at 158,000 yen on July 1.
The gadget locates its current position using two or three space
satellites called Navstar, which were launched by the U.S. Defense
Department. The device can locate one's latitude, the altitude, and
the navigational speed. This device can be used for sailing, fishing,
diving, gliders, mountaineering, and hiking. It can also be installed
in a car as a navigator.
Sony will also release the GPS core unit, which it says can be
hooked into a personal computer through an RS-232C port. This
system is expected to appeal to transportation firms. Japanese car
makers Mazda and Honda, meanwhile, have developed their own GPS
system and have installed it in their cars for low-end consumer
use. Pioneer has developed a GPS system with a 4-inch LCD and
CD-ROM-based area maps. Consequently, GPS systems are seen as the
next technology wave in Japan.
Currently, there are 15 satellites floating in orbit. Nine more
satellites are expected to be launched and will go into operation by
1993. With these satellites, one's position should be locatable
practically anywhere on Earth.

| The present conversion rate is about 150 yen per US dollar,
however the price will most likly be marked up in the US
to allow for the US import company to make money. (even if
it is the same company)
So I would guess you are looking at greater then $1000
and with mark ups it could go over $2000.
For example a piece of amateur radio equipment that sells for
$300 dollars in Japan ends up listing in the US for $600.

Interesting - I remember seeing a book in a bookstore called something
like "Why Japan Isn't Going to Make It" (can't remember the author).
One of his points was that Japan's consumer distribution network is
horribly inefficient. He cited as an example that if you are in Japan
and you want to buy a cordless phone, it's more expensive to buy a
Japanese phone that stayed in Japan than one that was first imported
into the US, then imported back into Japan.

Subject: Navigation satellite launched
Date: 23 Feb 92 23:29:39 GMT
CAPE CANAVERAL, Fla. (UPI) -- A Delta 2 rocket carrying a $65
million military navigation satellite finally thundered away into the
evening sky Sunday on a flight marking the first launch of a
``Navstar'' satellite in seven months.
Running nearly three weeks late because of a fuel valve leak
and bad weather last week that blocked two launch tries, the 126-foot
Delta 2 flashed to life at 5:29 p.m. EST and majestically streaked
away into the twilight sky.
On board the slender rocket was a Global Positioning System
``Navstar'' satellite, the 12th in a globe-spanning network of such
spacecraft that allow military forces on the ground, at sea and in the
air to determine their location and altitude to within 53 feet
anywhere in the world.
After an apparently flawless boost into space, the satellite
was released into a preliminary orbit about 25 minutes after liftoff.
Onboard rockets were scheduled to fire later to put the satellite in
a circular 12-hour orbit 12,500 miles up.
Sunday's flight marked the first launch of a Navstar satellite
since July 3, 1991, because of problems with the system used to orient
the spacecraft in orbit. Those problems have since been resolved and
subsequent launchings are expected every few months.
The Air Force plans to launch 21 upgraded ``block 2'' GPS
satellites - one from a space shuttle - to join seven older and less
sophisticated ``block 1'' spacecraft already in orbit.
The satellites are built by Rockwell International's Satellite
Systems Division in Seal Beach, Calif., under a $1.2 billion contract.
When the program is complete, four GPS satellites will be
``visible'' at any given time from anywhere on Earth. Military forces
on the ground, at sea or in the air will be able to use radio signals
from the satellites to pinpoint their locations to within about 53 feet.
McDonnell Douglas Space Systems Co. of Huntington Beach,
Calif., was awarded a $316.5 million contract Jan. 21, 1987 to build
seven Delta 2s for the GPS program. The contract included options for
13 additional vehicles for a total contract value of $669 million.
Under the terms of the contract, McDonnell Douglas receives a
$3 million incentive fee for every successful flight. But if any of
the first 18 rockets fails for any reason, the company will forfeit
future payments and will have to return the incentive fees paid to
that point, with interest.
``We bet $54 million on every launch,'' said one company official.
Prior to Sunday, the Delta record stood at 28 successes in a
row dating back to May 3, 1986, and a perfect 20 straight for the
upgraded Delta 2.
Launch originally was scheduled for Feb. 4, but the flight was
delayed two weeks because of a leak in a second stage fuel valve.
Launch tries last Tuesday and Wednesday were called off due to heavy
clouds and rain.

CAPE CANAVERAL, Fla. (UPI) - A $30 million Delta 2 rocket
blasted off Thursday to put a $65 million military satellite into
orbit, the 13th in a globe-spanning network of navigation beacons.
The 126-foot Delta 2 rocket flashed to life with a burst of
flame at 11:20 p.m. EDT and quickly streaked away from the Cape
Canaveral Air Force Station, one week late because of high winds aloft
that scotched two previous launch tries.
Mounted inside a protective nose cone was a Global Positioning
System ``Navstar'' satellite, the 13th in a planned network of such
spacecraft that ultimately will allow military forces on the ground,
at sea and in the air to determine their location and altitude to
within 53 feet anywhere in the world.
The flight plan called for GPS No. 13 to be ejected into a
preliminary elliptical orbit about 25 minutes after blastoff. On-board
rockets were scheduled to fire later to boost the satellite into a
circular orbit 12,500 miles up.
The Air Force plans to launch 21 upgraded ``block 2'' GPS
satellites, built by Rockwell International's Satellite Systems
Division in Seal Beach, Calif., under a $1.2 billion contract.
Equipped with sensitive atomic clocks, four such satellites
will be ``visible'' at any given time from anywhere on Earth. Military
forces on the ground, at sea or in the are able to use radio signals
from the satellites to pinpoint their locations with unprecedented
accuracy.

Who Knows Where Your Are?
The Satellite Knows
Michael Morvice wanted his Minute Man Delivery service in Gardena
Ca., to live up to its name. A big obstacle: Dispatching the 40
truck fleet efficiently. Dispatchers had to remember each driver's
route and were constantly squawking over two way radios to track
their drivers. Now, dispatchers know at all times where each truck
is and can alter routes all day long to add last minute pickups.
Morvice says he can dispatch a truck a truck in half the time. The
technology that is speeding up Minute Man, called global positioning
system (GPS), has a huge potential in all sorts of businesses, from
tracking cargo on ocean going freighters to guiding jumbo jets.
Developed by the US DoD at a cost of $3 billion over the past 15
years, GPS proved itself in the Gulf War when soldiers were able to
pinpoint their position the trackless desert by consulting boxes the
size of paperback books that took readings from satellites. By
locking on to four satellites, a receiver can determine its position
to within 16 meters. By adding a second stationary receiver,
readings can be refined to centimeter accuracy.
Now companies ranging from tiny Minute Man to Sony Corp. and
NorthWest Airlines Inc. are trying to adapt GPS for widespread
civilian use. By combining GPS signals with other data, such as
digitized land maps, more intriguing systems are possible. For
example, intelligent vehicle tracking systems could show drivers on
small dashboard computer systems, how to circumvent a traffic jam or
where the nearest automatic teller machine is located. Stephen
Colwell, president of Colwell-Kirtland International, a Sunnyvale
Ca. consultant, says more than $100 million worth of GPS receivers,
about a third of the total market, were sold to nonmilitary users in
1991. For this year, he projects sales of $600 million, two-thirds
of which will be civilian applications.
While the market remains small, the early commitment by such big
names is impressive considering that the US government still
considers GPS experimental. Worse for customers, when the system
becomes fully operational in late 1993, DoD intends to continue to
artificially degrading the signals for national security reasons. By
fudging the clocks' signals by nanoseconds, the military is able to
throw receivers off by as much as 100 meters. That is enough to keep
an enemy from using the GPS signals to launch a missile. Critics say
it is also enough to slow down many commercial plans. Bob Buley
claims that anyone with enough receivers and computing savy will be
able to get accurate readings anyway. And if they can not, there is
always GLONASS, or Global Navigation Satellite System, a Navstar
clone developed by the former Soviet Union. Although not as well
developed as the US system, GLONASS is being tested by Northwest and
United Airlines. There may also be other options. Private satellite
networks designed for voice and data communications, such as
Motorola's Iridium system, can also emit signals for use in location
tracking. Loral and Qualcomm are also working on a string of low
orbiting satellites called Globalstar that will provide cellular
communications and positioning data.
As knowledge of GPS grows, so do potential uses. Satlock Inc., a
small startup in Stanfield Az., is developing a GPS based navigation
aid that will help aerial crop sprayers spread fertilizers and
pesticides more effectively. Instead of dropping 5x5 inch cards
with toilet-paper streamers or replying on farmhands holding
flagpoles to mark their last pass, the system uses readings from
satellites to keep an accurate record of where they have flown over
a crop field. A similar system has been tested for spreading from
tractors. By avoiding overspraying and overfertilizing, GPS is
expected to save money and reduce pollution.

-------------------------------
I is sad to report the demise of the Richmond, FL geodetic VLBI station
as a result of the fury of Hurricane Andrew.
The Richmond antenna was one of the original Howard Tatel designs, 60 feet
in diameter. It was originally built for the Carnegie Institute Dept. of
Terrestrial Magnetism in the late 1950s, when it was located at Derwood,
Maryland. About 10 years ago, Bill Carter of the Nation Geodetic Survey had
it relocated to Richmond where it was jointly operated by the US Naval
Observatory and NGS as one of the prime stations of the POLARIS, IRIS
and NEOS Earth Orientation networks, with technical support from NASA's
Crustal Dynamics Project.
Richmond is also a prime Geodetic GPS facility and in CIGNET, IGS and
FLINN. It had recently been equipped with a JPL ROGUE GPS receiver. The
status of the GPS hardware is unknown.
The following report from USNO's Jim Martin at the Washington Correlator
gives the pertinent information as we know it:

Richmond is located between Coral Gables and Homestead. The news reports
are that the Homestead had 90% devastation. The National Hurricane Center
at Coral Gables reported peak winds of 164 MPH when the wind sensor broke,
and also lost all of its satellite communications dishes.

Subject: Military satellites finding water wells in Indiana
Date: Sun, 18 Jul 93 22:17:35 PDT
BLOOMINGTON, Ind. -- U.S. military satellites orbiting Earth
about 11,000 miles above the ground are being used to determine the
exact locations of water wells in northern Indiana.
A portable device called a Global Positioning System (GPS)
unit lets geologists receive information from the satellites.
The resulting data can be used to locate underground water
sources and determine how potentially vulnerable they are to pollution
by industry or construction, explained geologist Rick Hill of the
Indiana Geological Survey (now an institute of Indiana University at
Bloomington).
IGS is doing the study this summer under a contract from the
state government's Department of Environmental Management.
Each well's latitude and longitude will be entered in a
computer database for use by state agencies in studies of water
resource planning and protection.
The project leaders hope eventually to include every water
well in Indiana.
To take advantage of the satellite capability, an IGS
geologist carries the positioning device to a water well and mounts
its antenna on a tripod over the well.
The device, measuring about 2 inches by 2 inches by 9 inches,
receives radio signals from at least four orbiting satellites.
Typically the unit must gather satellite signals for about 10
minutes to produce accurate results. By recording each signal's time
of arrival, the unit can calculate the distance between its antenna
and the satellite that sent the signal (the signal travels at the
speed of light, and the time it was sent and the satellite's location
are provided by the military).
Combining all this information from four satellites allows the
geologists to determine precisely where the well is on Earth's
surface. The calculated position is accurate to within 6-16 feet.

RELEASE: 93-165
Flight tests with a NASA research aircraft last week demonstrated the first
precision, automatic approaches and landings using Differential Global
Positioning System (DGPS) navigation satellite signals without relying on
complex processing techniques.
Wilcox Electric, Kansas City, Mo., and NASAUs Langley Research Center,
Hampton, Va., performed the tests using DGPS and a simple "code tracking"
signal-processing technique. The aircraft position accuracies achieved appear
to satisfy tough Federal Aviation Administration (FAA) requirements for
landings in low-visibility conditions, called "Category IIIB."
"We've picked up where other recent flight tests have left off," said Wayne
Dohlman, Wilcox Electric's Business Development Director. "This is the first
time a DGPS autoland has been achieved without the use of special equipment
or processing techniques such as pseudolites or carrier phase tracking."
Seventeen "hands off" approaches and landings were completed on Sept.
15 using Wilcox DGPS avionics installed in NASA's Boeing 737 research
aircraft. The flight tests at NASA's Wallops Flight Facility, Wallops Island, V
a., were conducted under an agreement to test new flight technologies.
Ground instrument data to confirm that the tests achieved Category IIIB
accuracies will be analyzed next month, but observations based on flight
performance look encouraging.
"The system performed exceptionally well and consistently, especially for a
first flight test. I'm looking forward to analyzing the data," said Richard M.
Hueschen, NASA flight test project engineer.
The aircraft guidance information was unaided by the flight management
system or other avionics. The landings used raw, differential GPS guidance
supplied to the autopilot in the Boeing 737. A laser tracker, placed at a known
geographical reference point near the runways, served as an independent
reference system for aircraft-based measurements.
The code tracking technique used for the tests is a simpler way to
determine aircraft position that is expected to lead to more economical DGPS
ground systems and avionics. That could make satellite guidance of precision
approaches and landings practical for commercial aircraft.
The aviation industry now is doing tests with the Global Positioning System
to see if the satellite technology is feasible for widespread private and
commercial airline use in precision approach landings. The technology could
provide an inexpensive, worldwide, all-weather landing system. Differential
techniques are used to augment or correct raw signals beamed through space
from the GPS satellites.
FAA is evaluating DGPS readiness for precision approach and landing. FAA
and other international civil aviation authorities will meet in 1995 to examine
the results of these evaluations and agree on a worldwide policy for the use of
DGPS for navigation and landing.

o GPStech
The GPStech Mailing List
Operated by Jeff Freymueller, Stanford University
Jeff Freymueler has begun an unmoderated mailing list for the discussion of
GPS technical and other issues. The intention is to provide a forum for the
exchange of information, for discussion of the finer technical points that
always seem to trip us up, and for questions about particular GPS analysis
software.
GPStech is intended to be primarily for discussions and
question-and-answer. Hopefully there will soon be several list members who
are experienced with each of the commonly-used software systems, so that
questions can be answered. Any message sent to the list account is
immediately sent out to all members of the list. All messages willbe
automatically archived in daily files.

5. GPS BIBLIOGRAPHY
-------------------
A GPS Bibliographic Subscription Service is offered by Canadian GPS
Associates, publishers of the Guide to GPS Positioning. This service provides
twice-yearly updated editions, listing GPS-related publications from journals,
newsletters, reports, and proceedings of GPS-related conferences.
The Premier Edition, issued in late 1992, contained 4,358 entries. This grew
from a 1,000-entry bibliography prepared in 1989 at the University of New
Brunswick for the U.S. Army Corps of Engineers (Dredging Research Program
Technical Report DRP-92-2, available in electronic form as message #5296 on
the U.S. Coast Guard's GPS Information Center Bulletin Board). At 8,802
entries, the July 1993 Edition has doubled in size.
The GPS Bibliography is available in both hard-copy and computer-readable form
on PC or Macintosh diskettes. The PC diskette version is available in either
the standard CSV (comma-separated-variables) text format, or dBase III format.
For Macintosh users, the format is tab-separated field text format.

NASA TRACKS LAND-SURFACE MOVEMENT IN JAN. 17 EARTHQUAKE
Oat Mountain in the Santa Susana range, just north of the San Fernando
Valley, jumped several inches during the 6.6 earthquake that struck Los
Angeles on Jan. 17, said a scientist at NASA's Jet Propulsion Laboratory
(JPL), Pasadena, Calif.
Other locations, including some communities, also were jerked into new
positions, said Dr. Andrea Donnellan, a JPL geophysicist.
The 3,618-foot-high (1,103 meters) mountain, jumped up 14.8 inches (38
centimeters). It also moved north 6.2 inches (16 centimeters) and west
5.5 inches (14 centimeters).
JPL has continuously operated stations at Oat Mountain and at Cal State
University, Northridge, since the earthquake. The data suggest that Oat
Mountain has risen about one more inch (2 to 3 centimeters) since the
quake. The site also moved slightly more than an inch (3 centimeters)
back to the south after the 5.0 aftershock Jan. 29.
"This is mountain building in progress," said Donnellan. Donnellan and
her colleagues measured the movements of the mountain and several other
Southern California locations following the devastating earthquake using
Global Positioning System (GPS) instruments -- ground receivers that
track orbiting navigation satellites.
The Defense Department's GPS network includes 24 Earth-orbiting
satellites at 12,400 miles (20,000 kilometers) that send microwave
transmissions to ground receivers worldwide.
NASA collects data from a global network of 45 stations. The data tells
scientists how far the Earth's surface has moved in any given period of
time. In addition, portable instruments are deployed at other locations
around the world.
Donnellan said the 6.6 quake occurred on a fault at the southern and
eastern edge of the Ventura Basin, a 62-mile (100-kilometer) by 6-mile
(10 kilometer) sub-surface feature that stretches from the Pacific Ocean
to the San Fernando Valley. At 9.3 miles (15 kilometers) deep, the basin
is one of the deepest sedimentary basins on Earth, she said.
Donnellan had been studying the basin since 1987 and came to the
conclusion its deep faults were capable of causing a serious earthquake.
In a paper she published in the science journal Nature last November,
she predicted the basin could suffer an approximately 6.4-magnitude
earthquake.
Her studies, using the GPS instruments, indicated the basin was being
squeezed from north and south about 0.3 inches (7 millimeters) a year by
the movement of the Santa Susana and Santa Ynez ranges.
"It's a north-south closure of the valley," she said. The figures came
from analysis of data recorded in the GPS receivers at several locations
around the basin.
She said she and her colleagues used computer modeling to look at the
faults beneath the basin from a considerable depth up to the surface and
saw they were locked, that is, not slipping to relieve strain. From that
model they calculated the potential magnitude of a quake that could
strike the region. Although the scientists predicted the locale and size
of the earthquake, they could not predict when such a quake might occur.
The Oat Mountain receiver was the location closest to the quake's
epicenter and over the highest density of aftershocks. The epicenter was
in the valley community of Reseda. The fault, however, is not a single
point, but affects a large section of surface ground. The hardest hit
area was the community of Northridge, immediately adjacent to Reseda.
Most of Northridge overlies the ruptured fault plane.
Several other communities along the basin also were jerked into new
positions. GPS data indicated that the community of Fillmore in Ventura
County, which lost much of its downtown section, moved west 2 inches (5
centimeters). The region near Castaic moved southwest 4.3 inches (11
centimeters) and down 3.5 inches (9 centimeters). Santa Paula and
Moorpark also were moved westward 1 to 2 inches (approximately 2.5 to 5
centimeters) and the Point Dune area moved due north 1.5 inches (4
centimeters).
In addition to analyzing scientific data from the earthquake, NASA's
Airborne Science and Applications program has been conducting surveys of
the damage in the area. Data from instruments aboard NASA's C-130 and
ER-2 aircraft has been provided to the Federal Emergency Management
Administration and local governments to help them assess the damage.
Both JPL's GPS studies and the aircraft surveys, managed by NASA's Ames
Research Center, Mountain View, Calif., are funded by NASA's Office of
Mission to Planet Earth, Washington, D.C. Mission to Planet Earth (MTPE)
is studying how Earth's global environment is changing. Using the unique
perspective available from space, NASA is observing, monitoring and
assessing large-scale environmental processes, focussing on climate change.
MTPE satellite data, complemented by aircraft and ground data, is
allowing scientists to better understand environmental changes and to
distinguish human-induced changes from natural changes. MTPE data, which
NASA is distributing to researchers worldwide, is essential to humans
making informed decisions about protecting their environment.

An Air Force Delta 2 rocket was successfully launched from Cape
Canaveral Aifr force Station tonight. The Delta was carrying the last
in a series of Global Positioning Satellites.
The Delta was scheduled to launch at 10:32 p.m. but was a few minutes
late. The wait was worth it because I got a great view from my front
yard -- as usual. The rocket climbed into a starry sky, streaking
southeasterward.
As it climbed, the low roar rumbled south from the pad and mingled
with the sound of a prop plane revinning on the runway at nearby
Melbourne International Airport.
As the rocket continued to rise like a star, the prop plane took off
and joined it in the evening sky.
I was joined on the lawn by my son who said he "just had to see a
rocket take off."
The cat wasn't interested.
My wife was asleep.

CAPE CANAVERAL, Fla (Reuter) - An Air Force Delta 2 rocket
blasted into orbit Wednesday carrying the 24th and final advanced
satellite in the U.S. military's Global Positioning System (GPS), a
$10 billion constellation of navigation satellites ringing the globe.
Blazing engines bathed the Florida coast in artificial
daylight as the 13-story booster rose from a seaside pad at 10:40 p.m.
EST with the $65 million Navstar.
The launch was delayed eight minutes while rocket engineers
investigated a guidance glitch.
The Navstar broke away from the $45 million Delta 2 rocket
about 25 minutes after launch and settled into an oval orbit with a
low point of 115 miles. Onboard engines will reshape the satellite's
path into a 11,500-mile-high circle.
The Delta 2 also carried a $10 million National Aeronautics
and Space Administration experiment to test a tether. About an hour
after launch, the rocket was to eject a small instrument package at
the end of a 12-mile-long cord.
The experiment is designed to test a concept -- originated as
science fiction in the 1800s -- that tethers could be used to generate
electricity for satellites or to change the orbits of spacecraft.
NASA flew an identical experiment on an Air Force Delta 2 in
1993 and declared it a success. The experiments are similar -- but on
a much smaller and simpler scale -- to the Italian Tethered Satellite
test that failed aboard a space shuttle in 1992.
The Navstar network satellites transmit radio signals that
can be picked up by pocket-sized receivers on the ground. The receivers
translate the signals into extremely precise navigation information.
Although designed for military use, the Navstar network has
spawned a $6 billion private industry. GPS receivers have found their
way into airplanes, cruise ships and rental cars.
A coded signal allows jets in the air, ships at sea and
troops on foot to pinpoint their locations within 50 feet .. Slightly
less accurate latitude, longitude and altitude data are available to
civilian users.
