On-orbit separable satellite propulsion service system

Abstract

The invention discloses an on-orbit separable satellite propulsion service system. The on-orbit separable satellite propulsion service system comprises a satellite platform and a propulsion service system; the satellite platform comprises an energy module and a control module; the propulsion service system comprises a structure module, a propulsion module, a driving unit, a power supply interfacemodule passive end and a data interaction module passive end; and a first docking frame, a power supply interface module active end and a data interaction module active end are arranged at the bottomof the satellite platform. Compared with the upper stage, the on-orbit separable satellite propulsion service system has the advantages that a propulsion service cabin and a satellite are designed inan integrated manner and modules such as a control module, an energy module, a navigation module and a measuring module are multiplexed with the satellite, the dry weight of the propulsion service cabin is greatly reduced, the carrier-to-interference ratio is increased, and efficient utilization of spacecraft resources is realized.

Description

technical field [0001] The invention relates to an on-orbit separable satellite propulsion service system, which belongs to the field of space control actuators. Background technique [0002] The upper stage that can stay in orbit for a long time can at least meet the needs of on-orbit work tasks for more than half a year. Its working characteristics are closer to those of space vehicles such as satellites, and the technology used is similar to that of satellites. In addition to the traditional upper stage In addition to the orbit transfer capability it should have, it should also have the capability of autonomous flight control, continuous energy supply capability, long-term on-orbit residence with service load, and autonomous multi-task execution capabilities. Under the full management of the propellant, this has exceeded the business scope of the delivery field, and it is essentially a typical space vehicle. [0003] Space powers such as Russia, the United States, and Eu...

AI Technical Summary

Problems solved by technology

[0005] There are currently two satellite orbit transfer schemes. One is to use the satellite’s own propulsion system to carry out orbit transfer. It needs to be equipped with a large-scale propulsion system in the satellite, resulting in a large weight of the satellite after entering orbit, which affects the performance of the satellite; the other One is to use the upper stage to complete the orbit transfer of the satellite. Since the upper stage is an independent aircraft, it needs to be equipped with a complete electronic system, and its dry weight is relatively large, which affects the effective quality of the satellite into orbit.
