534.0. "Soviet ABM test Satellite ??" by PARITY::BIRO () Wed May 10 1989 14:46
1988 113A Cosmos 1985 Launch 23 Dec 1988
ABM calibration mission launch from Plestsk Dec 23 on board a Cyclone
booster. The satellite was place into a 340x330 mile orbit inclined
73.6 deg. Shortly after achieving orbit, the spacecraft released two
object. Later it ejected two additional objects. It is possible that
the objects are not involved in ABM tracking tests. But U.S. analysts
said it is most likely that the four subsatellites are device's that
can simulate the midcourse phase of U.S. ballistic missile reentry
vehicles to allow Soviet ABM radars to practice tracking such objects.
The Soviets have performed such missions before, but this is the first
time they have matched a satellite that releases such objects with a
Cyclone booster launch into a 73.6 deg inclinations.
I just got my two line orbital elements set and it looks like
Cosmos 1985 is releasing more objects or is breaking up into
space junk, BUT they are still being released in pairs
(ie obj 19943/43 and 19958/59) so it is most likely ABM tracking test.
obj 19912 88-113L ( I dont have with me any older data)
obj 19943 88-113M released on 1989 day 116
obj 19944 88-113N released on 1989 day 116
obj 19958 88-113P released on 1989 day 119
obj 19959 88-113Q released on 1989 day 119
It may be intersting to do a visual sighting of this bird
to see if one can see the releasing of these objects
