Abstract
In order to meet the increasing demand for high-speed data uplink of spacecraft, more and more spacecraft have added high-speed TT&C (telemetry, track and command) channels besides retaining the traditional low-speed TT&C channels. This paper proposes a telecommand scheme under the existing spacecraft electronic equipment architecture and uplink data protocol framework, which combines the data processing of high-speed and low-speed TT&C channels, optimizes the data flow design, and gives an efficient and reasonable uplink Space data link protocol, the data fusion of high-speed and low-speed TT&C links is realized, which improves the reliability of the spacecraft and the flexibility of uplink data transmission.
