An onboard optical and radar system

The article considers the problem of GEO satellites defense against space debris like the satellites which have not been relocated to the storage orbit. Ajoint work of several satellite systems is necessary to provide the satellite safety in the space. The onboard optical and radar system is intended for the detection of the space objects and coordinates measurement. The authors consider the advantages of optical and radar equipment combining, operational principle and versions of the structure. The block diagrams for versions of the structure are considered. The authors consider the accuracy characteristics and estimate a system mass and power consumption.
