Ocean Remote Sensing System
|
|
The Space System Okean-01 has been operating since 1983, starting from
experimental launches of Kosmos-1500 satellites. Spacecrafts Okean-01
provide radar, microwave and optical images of Earth for the purposes of
sea navigation, fishery and coastal shelf usage. One of main tasks of
ocean sensing satellites is coverage of ice situation in Arctic and Antarctic
regions and Northern seas, to provide for shipping in complicated ice conditions.
The most valuable weather-independent information in cloudy conditions
in any time of the day can be obtained from RLS-BO side-looking radar
and information-gathering system from autonomous sea and ice stations.
Spacecrafts Okean-01 operate on near-polar circular orbits with altitude
600-650 km, inclination 82-83 °.
Okean-01 Regular Onboard Equipment
| Instrument | Main parameters |
| Side-looking radar RLS-BO |
Resolution - 1.5-2.0 km Swath - 450 km Wavelength - 3.2 cm |
| UHF-radiometer (RM-08) |
Resolution - 15 km Swath - 550 km Wavelength - 0.8 cm |
| Multichannel average-resolution scanning device (MSU-S) |
Resolution - 370 km Swath - 1100 km Spectral bands - 0.6-0.7 um; 0.8-1.1 um |
| Multichannel low-resolution scanning device (MSU-M) |
Resolution - 2 km Swath - 1900 km 2 channels Spectral bands - 0.5-0.6 um; 0.6-0.7 um; 0.7-0.8 um; 0.8-1.1 um |
| Kondor - system for collection and transmission of data from sea and ice stations | Transmission of data from stations, stations geopositioning |
|
Radio channels 465.0 MHz 137.0 MHz |
Downlinking to ground stations (main centers) Downlinking to network of autonomous stations |
Satellite's information system operates in both direct transmission
mode and recording to on-board recorder mode with later downlink to ground
station. Onboard processing combines in a single frame images of the same
surface region produced by RLS-BO, RM-08 and MSU-M instruments to the same scale
and close ground resolution.
