Intermittent tracking technique can be used in the global navigation satellite system (GNSS) receiver to reduce its power consumption. To the pedestrian and vehicle navigation in the urban areas, an open loop with the Kalman filter for the GNSS signal intermittent tracking is proposed and its tracking accuracy relationship with the duty cycle is analyzed. Simulation and experiment results show that,...
Vector tracking loop (VTL) can be regarded as a kind of integration of navigation filter and signal tracking. It has a better performance for weak signal and can recapture signal quickly, but its robustness and computation complexity is worse. This paper mainly studies a tight integration model of navigation filter and tracking filter, which remains the signal tracking filter in local channels and...
