Time Synchronization Maintenance Strategy for VLEO Satellites Operating Under GNSS Outage in the Intersatellite Data Relay System
Very Low Earth Orbit (VLEO) satellites, leveraging orbital advantages, have found extensive applications in direct-to-cell (D2C) communication, high-resolution optical and radar remote sensing. The intersatellite data relay system (IDRS) can offer wide-area coverage and flexible service, promising to provide round-the-...
