Abstract

The invention relates to a geostationary orbit real-aperture microwave detection satellite configuration in the field of overall satellite technology, including a satellite platform, a microwave detector, a microwave detector quasi-light system, a locking / release device, a solar wing, a data transmission antenna, and a light shielding Mechanism; the main reflector and sub-reflector of the microwave detector are pressed tightly on the satellite platform, and the main reflector and the sub-reflector are unlocked and unfolded in place after the satellite and rocket are separated; the quasi-optical system of the microwave detector is installed and embedded through a micro-deformation frame into the satellite platform; the solar wing is installed on the heat dissipation surface of the satellite platform; the data transmission antenna is installed on the top of the satellite platform through a bracket; the satellite platform and the microwave detector are inclined, that is, the earth observation axis and the satellite Z axis (ie + Z 地面 ) There is a certain angle between them; after the orbit is fixed, the over-constrained connection between the microwave detector and the satellite platform is unlocked, and the light blocking mechanism is deployed. The invention makes full use of the space resources in the carrying fairing, adapts to the mechanical environment and high-precision installation requirements of the active launch section, and realizes the high-precision deployment of the main reflection surface and the secondary reflection surface of the microwave detector.

Description

technical field

[0001] The invention relates to the general technical field of satellites, in particular to a configuration of a geostationary orbit real-aperture microwave detection satellite. Background technique

[0002] At present, geostationary orbit remote sensing satellites are mainly optical remote sensing satellites represented by Fengyun-4 and Gaofen-4. The observation spectrum ranges from visible light to infrared bands. The size of remote sensing instruments is generally smaller than or equivalent to satellite platforms. This type of remote sensing instrument is directly installed on the ground (that is, the earth observation axis is parallel to the Z-axis of the satellite), and the interface with the satellite platform is clear (usually several installation points are set on a plane), and they are generally thermally isolated , and there is no need to unfold the remote sensor. There are no strict requirements on the deployment sequence of the installed solar wi...
