To improve channel utilization, a multi-channel source packet downlink mode is designed for the multi-spacecraft combined configuration in deep space exploration. Concurrently, a multi-channel periodic multiplexing scheme for telemetry is implemented, adapting to different flight stages and telemetry mode switches. Multiple ground tracking stations receive spacecraft downlink data simultaneously. Addressing diverse user requirements, it is essential to investigate collaborative fusion processing methods for multi-channel, multi-source telemetry data with-in multi-spacecraft configurations. This approach is crucial for enhancing data utilization while ensuring reliability and validity. Telemetry data optimization criteria are established, a multi-source data optimization model is developed, and optimal data is selected for user deliver .
