Sensor simulator and satellite closed loop simulation system

Abstract

The invention provides a sensor simulator, which comprises a simulation server and a data interface converter. The sensor simulator can be simultaneously or separately taken as a sensor simulator for various sensors such as a star sensor simulator, a sun sensor simulator, an optic fiber gyroscope simulator, a magnetometer simulator and a GPS (Global Positioning System) simulator, so that the sensor simulator has the advantages of high generality and high expandability; and moreover, the formula of data output by the sensor simulator is the same as that of data output by a practical sensor physical device in a practical satellite control system, so that access to a satellite control closed loop simulation system is available and the simulation reliability can be enhanced effectively.

Description

technical field

[0001] The invention belongs to the technical field of satellite simulation testing, in particular to a sensor simulator and a satellite closed-loop simulation system provided with the sensor simulator. Background technique

[0002] As a key component in the satellite flight control system, the sensor is mainly used to measure the attitude data and orbit data of the satellite. For example, the star sensor is a high-precision space attitude measurement device with stars as the reference system and the starry sky as the working object.

[0003] Because the development of the satellite flight control system is very complicated and costly, it is often necessary to simulate the satellite flight control system in the initial stage of the development of the satellite flight control system. In the satellite flight control simulation system, the simulation equipment for the sensor is called for the sensor simulator.

[0004] The existing sensor simulators have a sing...
