Abstract

The invention provides a measuring system suitable for direction change of a super-large array plane. The measuring system comprises a multi-beam-point laser transmitter, a two-dimensional PSD sensor assembly, a measuring control unit and the super-large array plane. Wherein the multi-beam point laser emitter is connected with the measurement control unit, and the two-dimensional PSD sensor assembly is connected with the measurement control unit; a light beam output by the multi-beam point laser emitter irradiates the two-dimensional PSD sensor assembly; the two-dimensional PSD sensor assembly is arranged on the ultra-large array plane; the invention relates to an array with a super-large array plane of more than 2K * 2K The invention further provides a measuring method suitable for the direction change of the ultra-large array plane. Based on the multi-beam-point laser transmitter, the in-orbit absolute planeness and normal direction of the super-large array plane can be obtained, and direction change measurement of the super-large array plane can be achieved.

Description

technical field [0001] The invention relates to the technical field of spacecraft measurement, and in particular, to a measurement system and method suitable for pointing change of a super-large array. Background technique [0002] Due to the repeated and alternating changes of the space thermal environment, it is easy to cause the satellite structure to deform on-orbit, especially the on-orbit deformation of the satellite super-large deployable front. It is necessary to measure the on-orbit deformation of the spaceborne super-large front to provide data support for on-orbit deformation suppression and on-orbit correction. [0003] After searching, the patent document CN105444669B discloses a measurement system and measurement method for large-scale plane pointing change, including a linear laser transmitter, a one-dimensional PSD measurement point, a measurement controller and an information processor; the information processor and The measurement controller is connected t...
