Embodiment

[0039] (1) According to (1) in the method step of the present invention, collimation measurement is carried out to the reference cubic mirror on the ranging sensor, to establish the body coordinate system of the electronic theodolite measuring coordinate system and the ranging sensor. In the example, the industrial measurement system developed by Zhengzhou Chenwei Technology Co., Ltd. is used to measure the alignment of the reference cube mirror of the range sensor to establish the body coordinate system of the range sensor. Afterwards, the angle intersection constructs the electronic theodolite industrial survey coordinate system. In this step, the industrial measurement system includes a set of SMN measurement software developed by Zhengzhou Chenwei Technology Co., Ltd., three TM5005 electronic theodolites (T3000 electronic theodolites) produced by Swiss Leica Company, a calibrated 1096 mm carbon fiber or indium steel ruler.

Abstract

The invention discloses a ground measurement method for accuracy of a distance measurement sensor for rendezvous and docking of airships. The coordinate system of a distance measurement sensor body is visibly derived by using an electronic theodolite measurement system, and a plurality of kinds of the coordinate systems are converted by combining a controlling field method. The coordinate system of the distance measurement sensor body and the coordinate system of the controlling field are unified by using a high-precision ground measurement control network. Distance measurement is performed on a reflection target of the distance measurement sensor by using a high-precision total station. The data of the plurality of kinds of the coordinate systems is integrated according to existing measurement data so as to deduce the relative distance between the distance sensor and a target marker; and the relative distance is compared with the actual measurement result of the distance measurement sensor so as to obtain the measurement accuracy of the distance measurement sensor finally.

Description

technical field [0001] The invention belongs to the field of electronic measurement, and relates to a ground measurement method for the accuracy of a range-finding sensor. Background technique [0002] Spaceship rendezvous and docking is a key technology of space technology. The ranging sensor is used to measure the distance between the two spacecraft in space from 30km apart to the final docking process, and to measure the relative motion speed between the tracking aircraft and the target aircraft in the final stage of approaching . The ranging accuracy of the ranging sensor at this stage is the key to the success of rendezvous and docking. [0003] In the ground experiment of spacecraft rendezvous and docking, it is necessary to verify the distance measurement accuracy of the ranging sensor. Considering the impact of ground conditions on the ranging sensor, the ground experiment verifies the range of 10km. At present, there is no verification method for the long-distan...
