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 ecologicalEcology
Ecology is the scientific study of the relations that living organisms have with respect to each other and their natural environment. Variables of interest to ecologists include the composition, distribution, amount , number, and changing states of organisms within and among ecosystems...

Specifications
Sensors- 8 m panchromaticPanchromaticPanchromatic film is a type of black-and-white photographic film that is sensitive to all wavelengths of visible light. A panchromatic film therefore produces a realistic reproduction of a scene as it appears to the human eye. Almost all modern photographic film is panchromatic, but some types are...

Data communications
- Transmission speeds of 15.36/61.44/122.88 Mbit/s
Orbit
- Altitude: 550 km - 97.5 degree sun synchronousSun-synchronous orbitA Sun-synchronous orbit is a geocentric orbit which combines altitude and inclination in such a way that an object on that orbit ascends or descends over any given point of the Earth's surface at the same local mean solar time. The surface illumination angle will be nearly the same every time...

Communications problems
After launch communications with Monitor-E was difficult to establish, initially. But a few hours later it was successfully contacted. On October 19 new problems developed and no communication was possible since then. Later on communications were restored and photographs from both cameras have been published on November 30, 2005.External links
