RESURS
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.
RESURS-F
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).

RESURS-01
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.
