Supplementary notes:

(1) Possibly an ocean survey type reconnaissance satellite. Previous flights of this type of vehicle were Cosmos 1094 (1979-33A) and Cosmos 1096 (1979-36A). Orbital data are at 1980 Mar 14.5 and Mar 14.7.

(2) Probably a navigation satellite.

(3) Interception test radar calibration target. See note 6 below.

(4) Unmanned supply vehicle carrying replacement parts and materials to Salyut 6 prior to the Soyuz 35 visit. The first two orbits are based on estimated data and are at 1980 Mar 27 and 1980 Mar 28. The third orbit, after docking at 1980 Mar 29.8, is at 1980 Apr 7.8. This orbit was achieved by an upward manoeuvre of the Salyut/Progress complex on 1980 Apr 3, using the Progress 8 engine.

(5) Orbital data are at 1980 Apr 1.7, Apr 2.1 and Apr 6.1.

(6) Target for Cosmos 1174 satellite interception test.

(7) Ferry vehicle which carried Leonid Popov and Valery Ryumin to Salyut 6. Launched at 1338 UT on Apr 9,

docking took place at 1516 UT on Apr 10. Orbital data are at 1980 Apr 9.8, Apr 10.3 and Apr 13.2.

(8) Cosmos 1172 may be an early warning satellite. Orbital data are at 1980 Apr 13.9 and Apr 18.9.

(9) Orbital data are at 1980 Apr 17.5 and Apr 18.1.

(10) Satellite interception test using Cosmos 1171 as its primary target. Orbital data are at 1980 Apr 18.1 and Apr 18.6.

(11) Probably a failed Molniya-3 satellite.
