Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of satellite single machine ground testing, and more specifically to a VPX switching device applied to satellite ground testing. Background Art
[0002] With the advancement of technology, the growth of market demand and the improvement of commercialization, the application fields of satellites are constantly expanding, playing an important role in communications, meteorology, remote sensing, broadcasting, navigation and other fields. It has also driven the growth rate of satellite services and ground equipment manufacturing industries to significantly exceed that of satellite manufacturing and launch services, and their proportion in the entire satellite industry chain continues to rise.
[0003] Satellite constellation systems have the advantages of high stability, low latency, no reliance on ground infrastructure, lightweight terminals and global coverage. Given the strategic importance of orbital spectrum and the relative technological advantages of satellites, the domestic low-orbit satellite industry is currently in its infancy. As satellite Internet is included in the scope of new infrastructure, relative technological upgrades and business model innovations are also being invested in the satellite field, making the satellite industry information-based and mass-produced.
[0004] The ultimate goal of satellite mass production is to solve the problem of simulating the onboard environment to complete ground testing and experiments on a large number of satellites and their individual units, so as to discover problems and eliminate faults in a timely manner to achieve the goal of preventing problems from happening.
[0005] At present, most commercial satellites adopt a stacked design. The integrated electronic motherboard and each stand-alone module are connected by a VPX connector. The pin gap of the VPX connector is 1.8mm, which is not convenient for direct measurement with instruments such as multimeters and oscilloscopes. During the desktop test of satellites, it is often necessary to measure certain power supplies and signals. If measured directly, it is very easy to cause a short circuit and cause irreversible damage to the on-board unit. At present, there is no relevant equipment to solve this problem. Therefore, designing a VPX adapter for satellite ground testing has become a problem that needs to be solved in the industry.
