HONGKE SOLUTIONS] The Effect of Gaussian Noise on Positioning Effect in GNSS Simulation
In Global Navigation Satellite System (GNSS) radio frequency simulation testing, Gaussian white noise (AWGN) is typically regarded as the baseline configuration for replicating real-world electromagnetic environments. However, engineering practice has shown that the impact of noise on a receiver’s positioning performance does not follow a linear, monotonic relationship. Based on actual measurement data from the DST GNSS simulator, this paper analyzes the physical mechanisms of Gaussian noise in Kalman filters, correlator jitter, and phase-locked loops, and provides a scientific testing guide for configuring simulation noise.
