Rapid and random temporal fluctuations in amplitude and phase of signal caused when GNSS signals are propagating through irregularities in electron density of the ionosphere are called amplitude and phase scintillation. Ionospheric scintillation can degrade receiver tracking performance, and in extreme cases, out of lock entirely. The elfect of amplitude scintillation on the signal is similar to that...
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,...
