Abstract: A system and a method are disclosed for smoothing Global Navigation Satellite System (GNSS) data. In some embodiments, the method includes receiving a first estimate from a navigation engine of a Global Navigation Satellite System (GNSS) receiver, and processing the first estimate with a first Kalman smoother.

Abstract: An apparatus and a method are provided. The apparatus includes a receiver configured to receive a signal over channels, a channel estimator configured to estimate the channels as first channel estimates; and a processor configured to compress the channel estimates to reduce buffer size. The method includes receiving a signal over channels by a receiver, estimating, by a channel estimator, the channels as a first channel estimate; and compressing, by a processor, the channel estimates to reduce buffer size.

Abstract: A system and a method are disclosed for handling outages in a Global Navigation Satellite System receiver. In some embodiments, the method includes: determining that a measure of combined signal level is less than a threshold, the measure of combined signal level being a measure of a signal level on a first channel of a Global Navigation Satellite System receiver and measure of a signal level on a second channel of the Global Navigation Satellite System receiver; and opening a tracking loop on a third channel of the Global Navigation Satellite System receiver.

Abstract: A system and a method are disclosed for detecting a spurious signal in a Global Navigation Satellite System (GNSS) receiver. A detector of the GNSS receiver determines a first sequence of known bits or known-bit transitions of a space vehicle (SV) signal of a target SV. A second sequence is determined based on a coherent sum of the SV signal being tracked by the GNSS receiver. A first reliability sequence may be associated with the first sequence, and a second reliability sequence that may be associated with the second sequence. A correlation statistic of the first sequence is determined based on the second sequence. Whether the first SV signal is a spurious signal is determined based on a comparison of the correlation statistic to a threshold value.
