Abstract
Service modes of single access and multiple access for data relay satellite system (DRSS) are presented in this paper. According to independent link resource scheduling for two types of access, rapid response service mode with single access link and multiple access link satellite co-processing is proposed, which using data relay satellite (DRS) multiple access return links panoramic beams as application channel. Users’ access applications could be processed with digital beamforming at the ground center station (GCS) without changing the status of DRS and GCS. Access application can be rapidly responded by scheduling available single access and multiple access link resources with single or several satellites from GCS after request accepted. Users in orbit could achieve real-time or quasi-real-time access by applying online with both random access and rapid access. Rapid response service extends the normal service mode of data relay satellite system. Simulation results show the capability improved by optimization of system resource allocation. And these improve the efficiency and flexibility of service capabilities of DRSS.
