On December 16, 1972 VPK Military Industrial Commission ordered the development of third generation meteorological system. This uses the Planeta-S sensor package in the system of non-co-3-plus system of geostationary orbital Meteor Electrical, which is to begin testing in 1982. The project design for the Planeta-S finished in 1979, followed by detailed design in May 1980. Resolution 1981 called for an integrated system of meteorological Planeta. It is developed by NN Sheremtyevskiy VNIIEM MEP and Yu V Trifonov. Electrical components development ran into major obstacles in the period 1983-1987, with a mock-up does not start over until 1989. Only then is a picture to complete the flight article. Electro many delays were due to both equipment and software problems, and the project went through two head development (Andronik Iosifiyan and Vladimir Adasko). Finally, there is only a single launch of Electrical, in 1994. Troubled spacecraft could not be put into use. The whole project eventually canceled, the official reason became head of development at VNIIEM competent.
In the west of Electrical Geostasionar designated Operational Meteorological Satellite (GOMS) system. Originally published for its maiden flight in 1978-1979, GOMS is known to suffer from both technical and budget problems. The purpose of the program, as stated in 1991, are as follows:
* To obtain, in real time, television images of Earth surface and clouds within a radius of 60 degrees centered on the sub-satellite point in the visible and IR spectrum;
* To measure the temperature profile of the Earth's surface (land and sea) and cloud;
* To measure the state of radiation and magnetic field environment of space at an altitude of geostationary orbits;
* To send a picture via digital radio channels, temperature and radiation and magnetometric information on main and regional data receiving and processing centers;
* To obtain information from Soviet and International data collection platforms (DCPs), located in the radio visibility GOMS, and to transmit the information obtained for the main and regional data and process-center;
* To transmit meteorological data is processed in the form of facsimile or alphanumeric information from the receiving stations and processing centers to the independent receiving stations via satellite;
* To provide high-speed exchange of digital data (retransmissions via the satellite) between Main and regional centers of the USSR State Committee for hydrometeorology;
* To call for `the data collection platform to send information to satellites.
GOMS Network is composed of three planes is 90 degrees apart in the geostationary ring: at 14 degrees W, 76 degrees E, and 166 degrees E. Each spacecraft's 2.6-metric-ton payload would have a capacity of 650-900 kg with an operational period is estimated at least three years.
The spacecraft is 3-axis-stabilized and receive a maximum of 1.5 kW (900 W for the payload) that is produced by two rectangular solar arrays. Twelve-related communication channels spacecraft to the centers of reception and processing, receives independent data centers, and data collection platforms. The main data receiving and processing centers located in Moscow region while the two regional centers located in Tashkent and Khabarovsk.
Satellite Electrical equipment suites for the first mission did not include 6 to 7 micrometers planned scanning Radiometer. telephotometer was limited to a total of 24 frames per day (each session lasts 30 minutes framing the imaging time 15-20 minutes), and only 4-5 frames can also be taken in 30 minutes per-frame rate imaging. This high frame rate will usually be employed around 0000 and 1200 GMT, in part, to allow the calculation of wind speed and direction data. DCP information should be collected and transmitted at intervals of three hours each day, ie, 0300 GMT, 0600 GMT, dl
