The Russian Earth observation program RESURS actually includes two distinct components: RESURS-F, which originates from the military reconnaissance satellites system, and RESURS-01, inherited from the METEOR-PRIRODA program, more oriented toward the study of the environment.

The RESURS-F program started in 1979 with the launch of the first satellite, initially listed as COSMOS. These reconnaissance satellites, designed for ecological studies and natural resource analysis, have operated for more than 40 years.

Orbiting at low altitude (170-275km), these satellites with short mission lifetimes were equipped with high resolution cameras (KFA-100 camera on board RESURS-F1 had a resolution of 4 to 7m, the panchromatic camera on board RESURS- F3 had a resolution of 2m) which were released after a few weeks for return to Earth.

In the continuity of the RESURS-F program, the satellite RESURS-DK1 was launched in 2006, with on board a sensor designed to collect digital data with a resolution of 1 meter in panchromatic mode and 2-3 m in multispectral mode. The images are transmitted by radio signal to ground stations, which greatly reduces the time needed for data availability. Satellites RESURS-P1 and P2 should ensure the continuity of the program, with the first launch scheduled for 2010..

Earth Surface Imager (ESI) Sensor

ESI is a pushbroom imaging instrument providing high-resolution imagery in the visible and near infrared spectral range, useful for commercial and research applications.

The instrument provides panchromatic and multispectral imagery in a total of 4 bands. A survey observation mode provides image scenes of up to 2100 km (along-track). The instrument can be tilted in the cross-track direction for an improved FOR (Field of Regard), this is done by spacecraft body-pointing (± 30º).

The Russian Resurs-01 satellites were developed to monitor the environment and map the location of natural raw materialsresources (forests, crops, snow and ice cover, coastal areas...).

These satellites were equipped with MSU-E (3 bands in VNIR with a resolution of about 30 m) and MSU-SK sensors (5 spectral bands at an average resolution of 170-210m), ideally suited for bridging the gap between Landsat images on the one hand and SPOT images on the other, and for bringing out regional emphases in a global study.

The program, which began in 1985, was completed in 2002, with the satellite Resurs-01 4.
