Optimization of Satellite Onboard Information Flow Based on CANFD Data Bus
Guojun Li, Xiao Li, Da Wei Lv, Junyu Li · 2023
CANFD data bus is introduced in this paper to optimize satellite onboard information flow, including telemetry, telecontrol, time synchronization, high speed upload data distribution and other self-defined in-orbit processing flow. Uniform frame format is defined in this paper to simplify onboard software complexity.
