SICH-1M Spacecraft (removed from service). / July 1, 2008 /

Tasks to be Fulfilled
According to the instrument payload installed on the SICH-1M, the researches of both water surface (ice, hummock, iceberg thickness measurement, river flood data acquisition), and land surface (assessment of crop maturation, soil erosion, drought-affected region area, ecological and man-made disaster scope and extent) may be undertaken.

Special features
The spacecraft’s instrument package offers improved characteristics of the onboard scanners and side-looking radar, and the availability of the MTVZA-OK multi-spectral scanner and the VARIANT science equipment complex as parts of remote sensing facilities.

The SICH-1M instrument payload will allow observation of the Earth from space in optical, IR, and microwave regions. The RLSBO microwave side-looking radar and the RM-08 scanning radiometer extend the capabilities of observations under cloudiness and in the nighttime. The optical-microwave scanner provides the Earth’s temperature and humidity sounding and the VARIANT science equipment complex measures the parameters of the Earth’ electric and magnetic fields.
