Description

technical field

[0001] The invention relates to the field of chip design, in particular to a method for designing a satellite control processor chip. Background technique

[0002] Compared with traditional satellites weighing several tons, commercial satellites have the characteristics of small size, light weight, and low launch cost. In recent years, with the continuous growth of people's demand for navigation enhancement, satellite-ground communication, disaster monitoring and other fields, the launch mission of commercial satellites has shown the characteristics of blowout growth.

[0003] The control computer is the control center of commercial satellites, and it is a very important on-board product to ensure the success of the launch and the completion of tasks in orbit.

[0004] It is generally composed of transponder, processor board (active and standby redundant configuration), signal conditioning board, GPS receiving module, payload data receiving and processing mo...
