Abstract

The invention discloses an on-orbit closed loop verification system for a satellite control system. The on-orbit closed loop verification system is suitable for on-orbit verification on new technology and products of the satellite control system. Close loop work conditions for the new technology or products to be applied to the satellite control system are established by running a satellite dynamics and kinematics calculation module, an executing mechanism control force or torque calculation module and a sensor measured value calculation module in a control computer. By the adoption of the on-orbit closed loop verification system, under the condition of lack of an executing mechanism, a sensor and even a controlled object, on-orbit real-time closed loop verification on new technology and products of the satellite control system can be achieved, and the authenticity of on-orbit verification on the new technology and the new products is remarkably improved.

Description

technical field [0001] The invention relates to an on-orbit closed-loop verification system of a satellite control system, in particular to an on-orbit closed-loop verification system of an incomplete satellite control system, which is suitable for on-orbit test verification of new technologies and products of the satellite control system. Background technique [0002] For a long time, the on-orbit test of new products (real sensors) of the satellite control system has adopted an open-loop verification system, such as figure 1 , that is, the verification and assessment of product performance and functions is carried out by transmitting the working information and status of the product in orbit through telemetry, and there is a lack of closed-loop verification and assessment. This is mainly due to the high cost of satellites and the high requirements for reliability. New products generally adopt the method of carrying for the first on-orbit verification. That is to say, the...
