Embodiment Construction

[0034] The present invention is an electric propulsion position maintenance method based on satellite time drive. Aiming at the characteristics of multi-track and multi-arc sections of the electric propulsion position maintenance task, the traditional electric propulsion position maintenance completely relies on the ground measurement and control network to start and shut down the thruster. The present invention adopts In the way of satellite time drive, the satellite performs the initialization work before the ignition of each orbit of the electric thruster, the steering adjustment of the vector adjustment mechanism, the parameter configuration of the electric thruster, and the processing of the start-up arc in chronological order. The invention realizes the electric propulsion multi-orbit and multi-arc automatic ignition task, improves the satellite's autonomous operation capability, the number of ignition orbits and the number of arcs can be flexibly configured on the ground,...

Abstract

The invention relates to an electric propulsion position keeping method based on star-time driving. The method comprises the following steps of: preprocessing electric propulsion ignition task parameters, and dividing the parameters into strategy parameters and attribute parameters according to whether the parameters are changed according to the characteristics of a task; and through star-time driving, sequentially carrying out initialization work before ignition of each rail of an electric thruster, steering adjustment of a vector adjusting mechanism, parameter configuration of the electric thruster and startup arc section processing according to a time sequence. The electric propulsion multi-orbit and multi-arc-section automatic ignition task is achieved, the autonomous operation capacity of a satellite is improved, the number of ignition orbits and the number of arc sections can be flexibly configured on the ground, and better flexibility and expandability are achieved.

Description

technical field [0001] The invention relates to an electric propulsion position maintenance method based on satellite time drive, which is mainly used for the software design and realization of the position maintenance of satellite electric thrusters, and belongs to the field of spacecraft embedded software design. Background technique [0002] Electric propulsion is a spacecraft propulsion technology that uses electric energy to accelerate the propulsion medium to achieve high specific impulse. The low propellant consumption brought about by high specific impulse can greatly reduce the amount of propellant carried. Compared with chemical propulsion, the use of electric propulsion system can prolong satellite life, improve on-orbit performance and increase load ratio. The application of electric propulsion to satellite orbit elevation and position maintenance has become a development trend. However, due to the small thrust of electric propulsion, the position of the electr...
