摘要:AbstractThe subject of the present research is a group of autonomously controlled small satellites, the mutual location of which must be maintained during the flight. The first step in solving this problem is to develop a measurement system and the most accurate estimation of the relative distances. It is believed that the group is accompanied by one or two relatively large satellites, the size and power capacity of which allows one to determine their exact coordinates using GPS or GLONASS systems. Objects that make up the group only have radio equipment for exchanging relatively simple navigation messages and a micromechanical inertial unit.
