Embodiment Construction

[0024] Such as figure 1 As shown, it is a schematic composition diagram of the autonomous navigation test system based on the earth-sun-moon integrated sensor of the present invention. The system mainly includes an integrated earth-sun-moon sensor, an earth simulator, a solar simulator, a moon simulator, the first single-axis turntable, the second single-axis turntable, an attitude-orbit simulator, a control computer and a navigation computer. The integrated sensor is installed on the second single-axis turntable, and the first single-axis turntable drives the integrated sensor, the second single-axis turntable and the earth simulator to rotate at the angular velocity of the satellite orbit. The attitude orbit simulator uses the satellite orbit dynamics model to calculate the satellite attitude orbit, and the calculation results control the rotation of the first single-axis turntable and the second single-axis turntable and the change of the chord width of the earth simulator....

Abstract

The invention provides an autonomous navigation simulation test system based on an earth-sun-moon integrated sensor. The earth-sun-moon integrated sensor is installed on a second single-axle rotary table to acquire measuring signals of the earth, the sun and the moon and send the signals to a navigation computer; a first single-axle rotary table drives an earth simulator, the second single-axle rotary table and the earth-sun-moon integrated sensor to rotate at a satellite track speed so as to simulate the self-rotation movement of a satellite; the second single-axle rotary table drives the earth-sun-moon integrated sensor to rotate so as to simulate the star rolling gesture; a gesture track simulator calculates the satellite gesture track and sends satellite reference track gesture data to a control computer; the control computer generates a track angular speed instruction according to the reference gesture track data to drive the first single-axle rotary table, generates a string width instruction to control the string width of the earth simulator and generates a rolling angle instruction to drive the second single-axle rotary table top rotate; and the navigation computer carries out navigation filter calculation according to the measuring signals, acquires the satellite position estimated value and the speed estimated value, and acquires the navigation precision by comparing the values with the reference data.

Description

technical field [0001] The invention belongs to the field of autonomous navigation and relates to an autonomous navigation simulation test system. Background technique [0002] The MANS (Microcosm Autonomous Navigation System) autonomous navigation system developed by Microcosm Corporation of the United States is one of the main contents of the TAOS (Autonomous Operation Survival Technology) flight test conducted by the US Air Force on March 13, 1994. The integrated autonomous navigation sensor used in the MANS autonomous navigation system is a pair of fan-shaped scanning sun and moon sensors added to the dual-cone scanning earth sensor. The navigation sensor uses a motor-driven optical scanning probe capable of multi-field sensitivity to Earth's thermal radiation as well as solar and lunar visible light. [0003] The report number is 92-1710, and the AIAA report titled "Autonomous Space Navigation Experiment" introduces the content of the TAOS flight test, which introduces...
