Abstract

The invention discloses a truss type supporting structure of a space wide camera. The truss type supporting structure comprises a camera frame, a truss assembly and a fixed frame, wherein the camera frame is connected with the fixed frame through the truss assembly; the fixed frame is provided with a threaded hole fixedly connected with a satellite platform; the truss assembly comprises 12 truss rods, 5 upper connectors and 4 lower connectors; the 5 upper connectors are 4 circumferentially uniformly distributed two-way connectors and 1 four-way connector arranged at the circumferential center;the 4 lower connectors are 4 circumferentially uniformly distributed three-way connectors; the four-way connector is connected with the 4 three-way connectors through the truss rods; the two-way connectors are connected with the two adjacent three-way connectors through the truss rods; the 12 truss rods are manufactured from a carbon fiber composite; and the upper connectors and the lower connectors are manufactured from a titanium alloy material. According to the truss type supporting structure, 4 high-resolution optical cameras can be mounted according to a certain angle, the large-mass cameras can be effectively supported, the detect that rigidity and heat stability of a conventional space camera supporting structure are relatively low is overcome, and optical imaging requirements of large-view field large-ground width space cameras are achieved.

Description

technical field [0001] The invention relates to a space remote sensing device, in particular to a truss type support structure of a space wide camera. Background technique [0002] As the main equipment for space observation of the earth, space cameras not only require high spatial resolution, but also require the satellite revisit cycle to be shorter and shorter, so as to obtain as much ground information as possible. However, due to the orbital height of the satellite itself and the high cost, it is often unrealistic for commercial spaceflight to realize the networking of multiple high-resolution satellites to shorten the revisit cycle, so the high-resolution, large-width space camera has become the only Solution. [0003] The support structure of the space camera is the main component of the space camera. It needs to provide reliable support and installation interfaces for each optical component, and at the same time resist the influence of the space environment on the o...
