Integration simulation test method of space optical remote sensor

Abstract

An integration simulation test method of space optical remote sensor belongs to integration simulation test technology. A comprehensive simulation test system composed of a comprehensive analyzing and processing device, a special simulation test device, an auxiliary simulation test device and a synchronous clock device is connected on a tested space optical remote sensor to realize real-time parallel integration closed loop simulation test. Under the reference of unitary time provided by the synchronous clock device, first the special simulation test device simulates the work of a space aircraft, or key parts, units or special functions of the space optical remote sensor, collects state, data and signals of the space optical remote sensor, and transmits to the comprehensive analyzing and processing device; then the comprehensive analyzing and processing device transmits the analyzing result to the auxiliary simulation test device in real time to be displayed, printed and transmitted to the special simulation test device in real time so as to form a closed loop simulation test, thus achieving the aims of predicting, judging and appraising the space optical remote sensor rapidly on the ground.

Description

technical field [0001] The invention belongs to the field of industrial automation and relates to an integrated simulation test technology for space optical remote sensors. Background technique [0002] The space optical remote sensor is the core equipment of the space vehicle. The control system of the space vehicle issues commands and control parameters to the space optical remote sensor, and controls the optical imaging system to complete the imaging task of the ground scene, such as figure 2 shown. Usually, space optical remote sensors have to go through many comprehensive tests such as desktop joint test, electrical test, various environmental test and electromagnetic compatibility test from the development of the initial sample to the launch of the real sample. Generally, it needs to go through five stages: program demonstration, design, initial sample development, positive sample development and flight test. In addition to the program demonstration, it is necessary ...

Problems solved by technology

With the rapid development of space optical remote sensor technology, these devices have fewer coverage test functions, which are limited to some subsystem tests, and there are still shortcomings such as incomplete functions, poor performance, low precision, and no comprehensive analysis and judgment capabilities. It has been far from meeting the requirements of space optical remote sensor testing, and cannot undertake the task of automatic ground comprehensive testing of space optical remote sensors, which has brought difficulties to the development of space optical remote sensors
