Resurs-O1 Chronology


03 October 1985 Cosmos 1689 Program: Resurs. Launch Site: Baikonur . Launch Vehicle: Vostok 8A92M. Mass: 1,500 kg. Perigee: 496 km. Apogee: 545 km. Inclination: 97.6 deg.

First flight of Resurs-O1. Acquisition of operational information on the natural resources of the earth in the interests of various branches of the national economy of the USSR; continued trials of new types of informational and measurement apparatus and methods of remote sensing o f the earth's surface and atmosphere. Operated for one year, two months.


20 April 1988 Cosmos 1939 Program: Resurs. Launch Site: Baikonur . Launch Vehicle: Vostok 8A92M. Mass: 2,000 kg. Perigee: 570 km. Apogee: 602 km. Inclination: 97.7 deg.

Investigation of the natural resources of the earth in the interests of various branches of the national economy of the USSR and international cooperation. Stayed in operation for six years, six months, far beyond its rated life of 3 to 5 years.


04 November 1994 Resurs-O1 No. 3 Program: Resurs. Launch Site: Baikonur . Launch Vehicle: Zenit-2. Mass: 1,900 kg. Perigee: 660 km. Apogee: 663 km. Inclination: 98.0 deg.

Studied natural resources. It carried the German Safir-R1 communications experiment as a secondary attached payload. Expected life 3 to 5 years.


10 July 1998 Resurs-O1 No. 4 Program: Resurs. Launch Site: Baikonur . Launch Vehicle: Zenit-2. Perigee: 815 km. Apogee: 818 km. Inclination: 98.8 deg.

In addition to its remote sensing equipment, the satellite carried the Belgian LLMS (Little LEO Messaging System) communications payload for the IRIS system. The launch was critical in restoring confidence in the Zenit vehicle prior to planned commercial launches of Globalstar satellites from Baikonur and the first Sea Launch flights using a three-stage Zenit from a California-based floating launch platform. Expected life 3 to 5 years.
