Problems solved by technology

Due to the more stringent requirements on the inclination angle and rigid body displacement index, the traditional integral casting frame structure has been difficult to meet the design requirements, and because the length of the main structure of the remote sensor is increased, the traditional integral casting frame structure is difficult to realize in the manufacturing process, and it is also difficult Difficult to meet the design requirements of high stability, high rigidity and high light weight of large size

Abstract

The present invention discloses discloses a supporting device for a space optical remote sensor. The supporting device comprises two external frames disposed oppositely, and an internal frame disposed between the two external frames. The internal frame is connected to the two external frames by means of a plurality of truss rods, respectively. The external frames are connected to the plurality of truss rods by means of a plurality of external joint assemblies. The internal frame is connected to the plurality of truss rods by means of a plurality of internal joint assemblies. By means of the split frames and the truss rods and using the joint assemblies for connection, the rigidity and strength of the supporting device are effectively improved with good structural stability, thereby meeting the requirements of large aperture and long focal length. The present invention also discloses a space optical remote sensor comprising the supporting device.

Description

technical field [0001] The invention relates to the field of space remote sensing, in particular to a support device for a space optical remote sensor. In addition, the present invention also relates to a space optical remote sensor comprising the above supporting device. Background technique [0002] With the rapid development of space remote sensing technology, higher requirements are put forward for the ground resolution of space remote sensors, and large-scale space optical remote sensors with large aperture and long focal length are increasingly being studied by people. However, as the optical aperture increases, factors such as gravity, thermal deformation, and the environment have more prominent effects on the optical quality of the remote sensor, and the difficulty of designing the supporting device also increases. The longer focal length means that the distance between the primary reflector and the secondary reflector of the optical remote sensor becomes longer, wh...
