LOCSS and its implementation on the basis of a small satellite cluster

A problem of providing users with the necessary remote sensing data in the visible and near IR spectral bands has been considered. The solution of the problem plans increase of spatial and spectral resolution for imaging from space, high periodicity of surveying the same sites on the Earth's surface and spaceborne data delivery to users in real time.

This problem solution proposed is to use a cluster of small satellites and to implement the Local Space Service (LOCSS) program. The main aspects of this concept are as follows:

• • optimization of remote sensing instrumentation parameters;

• • image data compression onboard a small spacecraft;

• • compressed data downlinking via the low rate radio channel;

• • direct reception of the image data by users at small cheap receiving stations; and

• • image data decompression and processing using personal computers and special processors.
