Automatic satellite precision detection method

Abstract

The invention discloses an automatic satellite precision detection method. The method comprises the steps that a measuring theodolite is arranged on a lifting support and is leveled, and a reference theodolite is arranged on a fixed base and is leveled; the two theodolites are used for building a station, and a relation between a reference theodolite coordinate system and a measuring theodolite coordinate system under a given measuring coordinate system is established; a satellite is arranged on a one-dimensional rotary table, a reference cube mirror on the satellite is measured through the theodolite, a satellite coordinate system is calculated, and a mutual relation among the satellite coordinate system, the measuring theodolite coordinate system and the reference theodolite coordinate system is obtained; a device drive value is calculated in combination with a design value of the cube mirror on the satellite; according to the calculated drive value, the one-dimensional rotary table,the lifting support and the measuring theodolite are driven to move; after rough collimation, accurate collimation is achieved through a visual guidance function of a CCD ocular lens; and values of the rotary table, the support and the measuring theodolite in an accurate collimation state are read, and an angle of the cube mirror on the satellite is calculated, so that the precision detection work is completed.

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
