The program of scientific research on the micro-satellite "Chibis" - "Basic research of the methods of the space monitoring of potentially dangerous and catastrophic phenomena with the use of micro-satellite technologies" - is a subprogram in the Program of basic research of the Presidium of Russian Academy of Sciences "Changes in the environment and climate, natural catastrophes". Space monitoring offers great possibilities for the detection and estimations of potentially dangerous and catastrophic phenomena on the Earth's surface, in the atmosphere, traced to the ionosphere and to the magnetosphere. Some problems, such as, for example, detection of forest fires are already successfully solved with the aid of the space means. On the basis of tasks named above the model composition of the useful scientific payload of the developed "Chibis" spacecraft is determined in the Space Research Institute of RAS, which includes: 1. Magnetic-wave complex (MWC). 2. Complex of atmospheric studies (CAS). 3. Complex of photometric equipment (CPE). The details of the micro-satellite "Chibis" are presented.
