Abstract
A Global Navigation Satellite System (GNSS) and method for switching between Phase Locked Loop (PLL) and Automatic Frequency Control (AFC) tracking loops inside the GNSS receiver is provided. The GNSS receiver acquires a signal from a satellite of a GNSS satellite constellation and receives information associated with external conditions that impact a decoding performance, or a phase or frequency tracking performance, of the GNSS receiver. The GNSS receiver updates a value of a switching threshold based on the received information and compares a strength of the signal with the updated value. The GNSS receiver selects a tracking loop as one of AFC or PLL, based on the comparison. Thereafter, the GNSS receiver generates, by the selected tracking loop, measurements associated with parameters of a carrier component of the signal and decodes satellite data of the signal based on the measurements.
