SPACECRAFT OPTICAL-MECHANICAL UNIT ASSEMBLING METHOD Russian patent published in 2017 - IPC B64G4/00 G01M11/00 B64G7/00 

FIELD: machine building.

SUBSTANCE: spacecraft optical-mechanical unit assembling method relates to space optical instrument-making and can be used in assembly, alignment and calibration of large-size optical-mechanical units, intended for operation in space. Method involves following operations: connection of optical and mechanical parts into single structure and alignment with subsequent monitoring of its optical-mechanical parameters under ground conditions before and after launch simulation, which is performed on test bench, at temperature corresponding to working orbit operating temperature, besides, additionally performing calibration under conditions imitating working orbit environment parameters, by results of which alignment quality is determined.

EFFECT: technical result of disclosed invention consists in fact, that optical elements alignment is stored not only after effects of overloads, vibration and impacts at launch, but at temperature effects during operation on orbit.
