Embodiment Construction

[0022] The present invention will be further introduced below in conjunction with the accompanying drawings.

[0023] like figure 1 Shown, be flow chart of the present invention, concrete steps are as follows:

[0024] The first step is to determine the working status of the equipment on the satellite that needs to be de-orbited, and at the same time analyze the remaining propellant on the satellite before de-orbiting. Among them, the working status of the on-board equipment includes the working status of the control and propulsion subsystem, the working status of the power supply subsystem, the working status of the payload subsystem, and the working status of the telemetry and remote control subsystem; Whether the agent is sufficient to complete the deorbiting operation of the current satellite.

[0025] The second step is to designate a satellite de-orbiting plan based on the working status of the on-board equipment and the remaining propellant determined above. The deor...

Abstract

The invention discloses a method used for navigating a CEO satellite to disorbit, which comprises the following steps: (1), ensuring the working condition of disorbited satellite equipment, and propellant residual condition of the satellite prior to disorbiting; (2), ensuring the satellite disorbiting scheme according to the working condition of disorbited satellite equipment and the propellant residual condition; (3), specifying the performance of a thruster used for the disorbiting of the satellite according to the satellite disorbiting scheme; and (4), utilizing the satellite disorbiting scheme implemented by the thruster used for the disorbiting of the satellite, and carrying out inactivation operation for the disorbited satellite after the completion of the disorbiting of the satellite. According to the method provided by the invention, the operation and requirements for navigating the CEO satellite to disorbit are given, so as to ensure the CEO satellite to enter an abandoned orbit after the service life of the satellite ends.

Description

technical field [0001] The invention belongs to the field of aerospace vehicle design and relates to an off-orbit method suitable for navigating GEO satellites. Background technique [0002] Satellite navigation has been widely used because of its advantages such as large coverage area, long operating distance, and little damage from natural disasters. With the development of aerospace science and technology, the ability of human beings to use space has been continuously enhanced, and space resources have become increasingly tense. The number of GEO satellites has increased sharply, and some satellites lose control every year and oscillate near the geosynchronous orbit, posing potential dangers to satellites in orbit and GEO satellites launched in the future. In order to reduce the space debris in geostationary orbit and purify the space environment in geostationary orbit, it is suggested that the satellites that are about to die should be sent to the graveyard orbit. Grav...
