Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as Figure 1-2 As shown, the remote sensing microsatellite configuration of the present invention includes a base plate 1, side plates 2-5, and a top plate 6. The six structural plates are connected to each other through structural protrusions and connection holes on the edge of the plate to form a cuboid closed structure (platform metal frame plate structure), the bracket 7 (load bracket integrated structure) is installed on the upper surface of the top plate 6. The two camera loads 8 given in this embodiment are installed on the same metal base 9, and the metal base is connected to the top plate 6 through fasteners. The solar wing 10 is connected to the threaded hole on the fixed wing through the through hole of the structural side plate 4 and the through hole of the bracket. The structure is connected (plate-type solar wing dep...

Abstract

The invention provides a low-orbit load platform separated remote sensing microsatellite configuration including a platform metal frame plate structure, a load bracket integrated structure, a frame separation mechanism, a plate type solar wing deployment mechanism and various devices. In a frame plate type structure, similar to a conventional base plate, side plate and top plate type structure, all structural plates adopt a thin metal plate + rib + lightening design; the whole structure adopts the base plate as the design and assembly standard, and a main force transferring route is from the base plate, to the side plate, to the top plate and then to the load. The load bracket integrated structure is mounted on a satellite top plate. A bracket can be connected to the top plate, the bracketcan be provided with a partial air-oriented device and can also be connected to a solar wing, the solar wing includes a one-fold fixing and two-folding unfolding type solar wing, and the solar wing is connected to the satellite side plate and the top plate bracket mainly through a fixing type solar wing. The microsatellite configuration has high space utilization, compact structure and small size, the final assembly process is good in openness, the test is convenient, and the configuration is not adjusted under the conditions of replacing the load of the same magnitude.

Description

technical field [0001] The invention relates to the technical field of spacecraft, in particular to a load platform-separated remote sensing micro-satellite configuration and an assembly method thereof. Background technique [0002] In recent years, with the improvement of payload resolution and the increase of spectral bands, high-resolution commercial remote sensing satellites are developing more and more rapidly. In order to meet the high installation, pointing, accuracy requirements and fast maneuvering of payload equipment, currently, the configurations surrounding commercial remote sensing satellites are mainly divided into two types, one is the configuration form of platform load integration, and the other is Platform and load separation configuration. [0003] The platform load integration configuration is mostly used in the occasions where the load is large and the satellite is heavy. In order to ensure the accuracy of the load and good mechanical conditions, the i...
