Successor to the Meteor-1 weather satellite. The Meteor-2 had a longer design operational life (one year vs. six months) and the capability to transfer data to automatically to military APPI stations (Autonomous Points of Information Collection). A total of 21 launches of the functional satellite were conducted from 1975 to 1993.

Work began to develop solutions for second generation hydrographic and meteorological observation systems in 1967. Prime contractor was VNIIEM Mineletrotekhprom (A G Yosifiyan). In 1969 the TTZ specification was issued by the Ministry of Defense and the Main Hydro - meteorological Office of the Soviet Ministers. Draft project was completed in 1971. Due to difficulties by NPO Geofizika in development of spectrometer equipment, the first test unit was not completed until 1975. Flight trials under Major General V I Sheulov commenced in July 1975. The original Vostok-2M launch vehicle was replaced by the Tsiklon-3 from the twelfth spacecraft on. Flight trials led to the system being accepted into service on 21 June 1982. A total of 21 launches of the functional satellite were conducted from 1975 to 1993.

The 1,300 kg Meteor-2 had higher tolerance dynamic characteristics and featured numerous sensors, including:

• Three-view optico-mechanical multi-spectral/infrared scanning television, with extended reception by ground stations at any point of each orbit. This consisted of two scanning, single-band (0.5-0.7 micrometer) telephotometers, one with a 2,100-km swath width and one with a swath width of 2,600 km, featured ground resolutions of 2 km and 1 km, respectively. A single band (8-12 micrometer) IR radiometer provided 8-km resolution over a 2,800-km swath.
• Radiometric sensor for uninterrupted observation of electromagnetic fields in space. This included a radiation measurement complex.
• Eight channel infrared radiometer for observation of global vertical temperature profiles. This radiometer covered bands between 11.1 and 18.7 micrometers and provided 37-m resolution over a 1,000-km swath.

The Meteor series served the Ministry of Defense by providing:

• Operational meteorological data for reconnaissance satellite scheduling
• Operational weather data for use by the Armed Forces in local and global operations
• Monitoring of radiation in near-earth space.

Flight trials began reasonable well, but delays were encountered due to the technological base at VNIIEM and Istra. Therefore a resolution of 4 June 1970 ordered VNIIEM to develop a parallel design of another meteosat for the hydrology office alone. This was not put into production. In its place a resolution of 16 December 1972 ordered development of a third generation system. This used the Planeta-S sensor package in the non-co-orbital Meteor-3 system plus the geostationary system Elektro. There were only seven launches of Meteor-3, and a single launch of Elektro, in 1994. Meteor-2 remained in service throughout this period and Meteor-3 was finally cancelled.

Meteor-2 satellites made possible the creation of atmospheric temperature and humidity profiles, penetrating radiation profiles, sea-surface temperature readings, sea-ice condition charts, snow-cover limit charts, cloud and surface images in the visible and infrared, and cloud-top height charts.

Meteors were originally launched by the Vostok booster into nominal orbits of 850 km by 900 km at an inclination of 81.3 degrees. During 1982-1984 the Meteor satellites were transferred to the Tsyklon booster and a new orbital regime of 940 km by 960 km with an inclination of 82.5 degrees.

Design Life: 2 years. Typical orbit: 890 km x 924 km at 82 degrees inclination. Mass: 2,750 kg (6,060 lb).

  Obtaining meteorological data and information on the radiation status of geovicinal outer space. The satellite included the Temisat German small space facility, which was separated from Meteor-2 on the seventh transit of the flight. Western interceptions of Meteor 2-21's transmissions indicated that the spacecraft did not perform as well as earlier vehicles in the series, particularly with regard to image quality and stable signal strength. The spacecraft operated through the end of 1994 on 137.400 MHz and 137.850 MHz, switching when required to avoid interference with other Russian Earth observation spacecraft.
