IRS-1B
1991-061A
The IRS-1B satellite was launched with the 8A92M rocket (Vostok-2M) from Baikonur, with NPO Lavochkin providing launch preparation services and Glavkosmos providing the interface. Control was from Bangalore. In 2001 the IRS-1B cameras were still operating well and the spacecraft was being used for systems tests.

Hexagon 17
1982-041A
The 1982 launch, mission 1217, was the first of a revised series which did not include the MCS. Instead, two SSS (S-cubed, Solid State Stellar) cameras mounted on the Two Camera Assembly and looking out the side of the main spacecraft section were used to provide attitude measurement for the main stereo pan cameras used in mapping mode. The Doppler Beacon system was retained and fixed directly on the forward bulkhead in the former location of the MCS, while the NAVPAC system was attached to the pallet. In addition, a new film looper reduced the amount of film wasted during typical operations.
The mission `provided an excellent data base of broad area search coverage on Communist countries and Third World areas of major concern to the Intelligence Community', according to a memo from the CIA director.
