Abstract

The invention provides a satellite image navigation and registering full-physical testing device and testing method. The satellite image navigation and registering full-physical testing device comprises a three-shaft air floating table (1), an optical axis measuring system (2), an adjusting mechanism (3), a wireless communication device (4), a photoelectric autocollimator (5), a camera mounting plate (6) and on-board testing equipment such as an imaging camera (7) (including a scanning mechanism), a solar panel driving simulation mechanism (8), a gyro assembly (9), a flywheel assembly (10) and the like. The working state on orbit of a satellite is simulated, and system-level tests are carried out. According to the invention, image navigation and registering air floating table full-physical test verification and performance testing can be carried out on different loads such as a small area array and two-dimensional scanning imaging camera or a large-aperture long-linear-array big area array imaging camera, and on-board image navigation and registering technical schemes and system indexes are enabled to meet on-board requirements.

Description

technical field [0001] The invention relates to the field of navigation and registration, in particular to a satellite image navigation and registration full physical test device and testing method. Background technique [0002] Image navigation and registration is a key technology to compensate for the influence of factors such as spaceborne camera scanning mirror motion interference, satellite attitude changes, orbital drift, and structural thermal deformation on the geometric application of remote sensing satellite images. The US three-axis stable geostationary orbit meteorological satellite, GOES-8 launched in 1994, began to solve the problem of image navigation and registration. It took 11 years to optimize the design of 5 satellites, and the GOES-13 satellite was launched in 2006, and the image navigation and registration performance was significantly improved. [0003] Image navigation and registration technology involves multiple systems such as satellite overall, a...
