Description

technical field [0001] The invention relates to the fields of control, monitoring and testing of pico-satellites, in particular to an integrated detection device for pico-satellites. Background technique [0002] Picosatellites refer to satellites with a weight between 1-10Kg. They widely use high-tech technologies such as MNT (Micro-Nano Technology) and MEMS (Micro Electronic Mechanical System) with high functional density and technical performance. Strong, more flexible launch mode, short development cycle, low development cost, simplified design, small size, low cost, and reduced risk of failure. [0003] Pico-satellite’s integrated detection equipment is an essential part of pico-satellite testing and application systems. It can be used in various tests of pico-satellites in different research and development stages, and can complete the communication tasks between satellites in orbit and the ground. , used to receive the downlink telemetry data of the pico-satellite fo...

AI Technical Summary

Problems solved by technology

[0006] 1. The function is single, and it is impossible to complete all the test work independently during the pico-satellite ground test, and it must be tested in conjunction with other test equipment during the test process

[0007] 2. The PC console uses UART to send instructions and receive data. Due to the limitation of UART communication rate, it cannot meet the ever-growing pico-satellite communication bandwidth.

[0008] 3. The structure of two-level up-conversion and down-conversion is adopted in the wireless communication link. Compared with the first-level up-conversion and down-conversion, the structure is more complicated, and the loss of signal quality is greater.
