THE CURRENT TASKS CONCERNING WITH CREATION AND DEORBITING OF THE FORMATION FLYING GROUPS FROM NANO- AND PICO- SATELLITES
Abstract
The purpose of the present paper is the analysis of current tasks concerning with creation and deorbiting of the formation flying groups consist of nano- and picosatellites and the consideration of the possibility of using permanent magnet devices for the deorbiting of these groups. During research was determined that it is most expedient to use small standardized spacecraft and use them during the development of distributed satellite systems. It can be both formations, and groups of satellites spaced a long distance. The analysis of the current possibilities for the removal of nano- and pico- spacecraft into orbit is carried out. According to the characteristics and properties of super-small spacecraft because of their super-small size and saving of the rocket fuel, it was determined that these spacecrafts proposed to be launch as a passing payload when large, expensive spacecraft is launched into orbit. To facilitate the integration of spacecrafts such as CubeSats with a carrier rocket, special multi-purpose dispensers were developed. The problems of controlling the configuration of the nano- and pico- satellites formations are shown. The analysis of deorbiting technologies of spacecrafts of the nano- and pico- satellites is carried out. The overview of modern well-known propulsion technologies of nano- and pico- satellites is carried out. The new method of creation and deorbiting of the formation flying groups from nano- and pico- satellites with using new constructive scheme “spherical dispensers” was proposed. The main axes of P-PODs are located along the radiuses of “spherical dispenser”. The technology of deploying and “clotting “of the formation flying groups from nano- and pico- satellites with using tether connection and hoist devices was proposed. The analysis of the possibility of implementation of devices with permanent magnets for nano- and pico- satellites is carried out. The low boundaries of effective work of the magnetic devices were determined. An alternative method for deorbiting nano- and pico- spacecrafts with the help of devices with permanent magnets using “clotting “technology is proposed
