features
Multi-Constellation & Multi-Band Support
Model 1 supports mainstream satellite navigation systems, including GPS L1/L2, BeiDou B1/B2, and GLONASS G1, fully meeting standard verification and production testing requirements.
Model 2 extends support to Galileo (E1/E5a) and additional frequency bands such as GPS L5 and BeiDou B3, eliminating the need for multiple single-system simulators. This significantly reduces overall testing costs for users working with diverse GNSS receiver platforms.
High-Precision Signal Reproduction
Model 2 delivers ultra-fine signal power adjustment with a 0.1 dBm step size, covering a wide dynamic range from -150 dBm to -80 dBm, and achieves time synchronization accuracy of ±10 ns. It accurately simulates weak-signal environments such as urban canyons and high-altitude scenarios, ensuring reliable validation of receiver sensitivity and positioning accuracy.
Model 1 supports stable 0.5 dBm step adjustment, making it well suited for standard production-line and routine performance testing.
Flexible Dynamic & Interference Simulation
Both models feature built-in dynamic scenarios (30+ for Model 1, 60+ for Model 2), covering constant-speed motion, acceleration, turning, and other typical navigation conditions.
Model 2 additionally supports interference simulation, including narrowband and broadband jamming, enabling comprehensive evaluation of receiver anti-interference performance. Users can import custom trajectories via CSV or KML formats to recreate industry-specific environments such as aircraft takeoff profiles or maritime navigation routes.
Intuitive Operation & Data Analysis
