About
SatSim is Quadsat’s satellite pass emulation product. Rather than testing a ground station antenna against a geostationary reference, SatSim programs the QS drone to fly the exact trajectory that a LEO or MEO satellite would describe across the sky above the station — at the correct angular rates and elevation profiles — while transmitting RF signals.
This enables ground station operators to validate autotracking performance, Doppler compensation, link budget margins, and scheduling systems under realistic dynamic conditions without requiring an actual satellite pass. SatSim supports both uplink and downlink configurations, and trajectory generation is based on TLE orbital elements or custom defined passes. The system is especially valuable for newly installed LEO ground stations being qualified before entering operational service.
