Working Principle
The GNSS signal simulator can be configured for dual-user simulation. Based on simulation time, user trajectory data, and satellite trajectory data, it generates navigation signals and outputs them to the receiver. The receiver subsequently outputs test data. By comparing the simulator’s theoretical data with the receiver’s test data, the performance evaluation of the receiver can be achieved.
