AI Technical Summary

Problems solved by technology

The real star sensor, due to the limitation of the star sensor processor and the stand-alone itself, cannot output real-time star sensor data, and all have delay characteristics, while the current digital star sensor simulator does not have delay characteristics or injection functions.

Embodiment Construction

[0013] The implementation process is as follows figure 1 and figure 2 As shown, the specific description is as follows:

[0014] A multifunctional star-sensitive simulator, including a receiving command processing module, a state setting module, a program injection module and a data reply module;

[0015] The instruction processing module is responsible for communicating with the onboard control computer, and receiving and responding to the instructions of the onboard computer. The receiving instruction processing module receives the data instructions sent by the external onboard control computer, divides the data instructions of the onboard control computer into status setting instructions, injection program instructions and data reply instructions according to their types, and sends them to the state respectively. Setting module, program injection module and data reply module; Simultaneously receive instruction processing module to receive the star sensitive time delay pa...

Abstract

The invention discloses a multifunctional satellite-sensitive simulator which comprises a command receiving and processing module, a state setting module, a program insetting module and a data reply module. The command receiving and processing module receives external data commands transmitted by a satellite-borne control computer and classifies the data commands to the state setting module, the program insetting module and the data replay module for processing, and real satellite-sensitive on-track operation is simulated. Aiming to solve the problem that digital satellite-module simulator with time delay and insetting function does not exist in existing satellite system verification, the multifunctional satellite-sensitive simulator with the advantages of insetting and time delay is designed, used for system closed-loop test of satellite control subsystem and a whole satellite and is the engineering test simulation technology which has been not used before.

Description

technical field [0001] This technology belongs to aerospace testing technology, and involves the establishment of star sensor model when ground testing is involved, so as to ensure the consistency between the star sensor model and the real product. Background technique [0002] In recent years, high-precision star sensors have been widely used in the satellite control subsystem. In order to complete the high-precision and high-fidelity system test of the satellite control subsystem, the static star sensor simulator cannot complete the system closed loop, and only the star sensor can be opened. Ring test; the use of dynamic star-sensing simulator can effectively conduct system closed-loop test, but due to the difficulty of installing the dynamic star-sensing simulator and the inability to install the whole star, the dynamic star-sensing simulator is only suitable for a short period of time It is usually used in the internal system test, usually 2-3 days, for the system test a...
