Inter-Satellite Links (ISLs) network is being deployed in the Global Navigation Satellite Systems (GNSSs) Constellation for auto-navigation, precise orbit determination and on-board clock parameters estimation purposes. It significantly reduces the need for ground stations and provides telemetry, telecommand, and ranging information in near real-time. We consider the elevation angles of all ISLs as system parameter for ISL scheduling strategy. We cluster the ISLs having similar signature and accordingly assign the time slots. The link scheduling strategy minimizes Position Dilution of Precision (PDOP) while optimizing ISL scheduling. The proposed methodology has low complexity and suitable for all GNSS satellite constellation.
