A kind of satellite automatic accuracy detection method

Abstract

The invention relates to a satellite automatic precision detection method, comprising the steps of placing the measuring theodolite on the lifting support and leveling it, and the reference theodolite being placed on the fixed base and leveling it; using two theodolites to build a station, and establishing the coordinates of the reference theodolite under the measurement coordinate system The relationship between the satellite coordinate system and the measurement theodolite coordinate system; the satellite is placed on the one-dimensional turntable, and the reference cube mirror on the satellite is measured by the theodolite, and the satellite coordinate system is solved to obtain the satellite coordinate system, the measurement theodolite coordinate system and the reference theodolite coordinate system. Interrelationship; Combined with the design value of the cube mirror on the satellite, calculate the driving value of the equipment; according to the calculated driving amount, drive the one-dimensional turntable, lifting bracket and measure the movement of the theodolite; after roughly collimating, rely on the visual guidance function of the CCD eyepiece to achieve precise collimation; Read the values ​​of the turntable, support and measuring theodolite under the precise alignment state, solve the angle of the cube mirror on the satellite, and complete the precision inspection work.

Description

technical field [0001] The invention relates to a method for satellite automatic precision detection, which belongs to the field of satellite testing and is suitable for satellite precision detection. Background technique [0002] Various complex structure sensors are often involved in the production of satellites. The attitude accuracy of these sensors is high, but it is not convenient for direct measurement. In the production inspection process, a cube mirror is often installed on the sensor, and the attitude information of the sensor is replaced by the collimation measurement cube mirror. [0003] At present, in satellite production, the accuracy detection of the cube mirror is mainly completed by manually operating theodolite collimation. This technology has many limitations and deficiencies: [0004] 1. The operation and control of the instrument in manual collimation measurement requires 3 to 4 people to complete the work, and the labor cost is very high; [0005] 2....

AI Technical Summary

Problems solved by technology

[0004] 1. The operation and control of the instrument in manual collimation measurement requires 3 to 4 people to complete the work, and the labor cost is very high;

[0005] 2. The alignment measurement of the cube mirror by theodolite relies on human eye observation. For more skilled operators, this link takes an average of 40 minutes to work. The measurement efficiency is low and the alignment accuracy is easily affected by human factors;

[0006] 3. Manual alignment measurement cannot use the existing measurement data, the measurement is difficult, the repetitive workload is heavy, the time is long, and the degree of automation is low;

[0007] With the continuous development of satellite products, the complexity of satellite structure has changed greatly, and technicians have higher and higher requirements for improving the automation level and production efficiency of cube mirror precision detection. Currently, manual theodolite measurement Technology can no longer meet the needs of reality
