The satellite is part of a space navigational system created with the aim of determining the location of naval and fishing vessels. Initial orbital parameters: period 104.9 min, apogee 1019 km, perigee 981 km, inclination 82.9 deg. 1991-006A INFORMATOR-1 was launched on January 29, 1991, by the U.S.S.R. using a COSMOS rocket booster. The satellite carries experimental equipment designed to collect and transmit information in the interest of the Soviet Ministry of Geology. Initial orbital parameters: period 104.8 min, distance from earth's surface 1,000 km, inclination 83 deg. C.
