Monitor-E is the first Russian satellite of a fleet of newly designed, small Earth observing satellites. It was launched 26 August 2005 at 18:34 UTC from Plesetsk Cosmodrome, and placed in a Sun-synchronous orbit of 524 by 544 km (326 by 338 mi).

Design

Monitor-E has a set of remote sensing devices. They are intended to make maps of the Earth's surface to be used for ecological monitoring and charting geological features. It was built by the Khrunichev State Research and Production Space Center.

Specifications

Sensors

  • 8 m panchromatic (0.51-0.85 µm), swath width of not less 90 km
  • 20–40 m multispectral (0.54-0.59/0.63-0.68/0.79-0.90 µm), swath width of not less than 160 km

Onboard storage

  • 2 × 200 gigabit capacity

Data communications

  • Transmission speeds of 15.36/61.44/122.88 Mbit/s

Orbit

  • Altitude: 524 × 544 km (326 × 338 mi) - 97.6 degree Sun-synchronous inclination

Spacecraft

  • Active life: 5 years
  • Orientation precision: 0.1 degrees
  • Stabilization precision: 0.001 degrees/s
  • Average daily power consumption: 450 W
  • Mass: 750 kg (1,650 lb)

Communications problems

After launch, communications with Monitor-E was initially difficult to establish, but a few hours later it was successfully contacted and control was established.[5] On 19 October 2005 new problems developed and no communication was possible since then. Later on communications were restored and photographs from both cameras were published on 30 November 2005.
