A Service Guarantee Mode for the Multi-satellite Collaboration-oriented Data Transmission of TDRS
Year: 2023
Type: conference-paper
Abstract: The tracking and data relay satellite (TDRS) plays a pivotal role in the current and future space-ground integrated network (SGIN). With an increasing number of spacecrafts, the demand for space-based data transmission based on TDRS is also expanding. This article, based on the current situation of multi-satellite collaborative observation by Earth observation satellites, firstly analyzes the main requirements for space-based data transmission. It then proposes a classified transmission strategy to transmit telemetry telecontrol instructions through S-band multiple access (SMA) links and observation data through S-band single access (SSA) /KA-band single access (KSA) links. Finally, a service guarantee mode that combines on-demand allocation and on-time pre-allocation is designed, with the purpose of improving the resource utilization efficiency and satisfaction rate of relay satellite in the context of multi-satellite collaboration.
