Abstract: Method, computer program product, and apparatus for signal tracking and decoding in GNSS are disclosed. In one exemplary implementation, a satellite receiver may be configured to receive a first sub-frame of a satellite signal. It defers a determination of validity of the first sub-frame until a preamble of a second sub-frame is received. The satellite receiver receives the preamble of the second sub-frame, and then determines whether there is a data decoding error of the first sub-frame using the first sub-frame and the preamble of the second sub-frame.

Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a receiver and/or other like device to determine an SPS time using SPS signals based on a correlation process. A verification process may be performed, for example, that verifies a maximum peak in comparison with other peak information resulting from the correlation process, for example, by considering a ratio of a maximum peak to a next maximum peak. A time-setting algorithm may be selected, for example, based, at least in part, on a time uncertainty and/or on a type of demodulation performed on the SPS signal. The time-setting algorithm may operatively control one or both of the correlation and/verification processes in a desired manner given the time uncertainty and/or type/mode of demodulation performed.

Abstract: Various techniques are provided which may be implemented in a mobile device to acquire a first positioning signal transmitted by a first transmitter of a first satellite in geostationary orbit, associate the first positioning signal with a coverage region to determine a rough position of the mobile device, and affect a positioning signal search strategy based, at least in part, on the rough position of the mobile device. The search strategy may identify at least one transmitter of at least one satellite in non- geostationary orbit that is estimated to be located in a position to transmit a second positioning signal within at least a portion of the coverage region, and which may be searched for by the mobile device. Such techniques may, for example, reduce a first time to a position fix in certain instances.

Abstract: A multipath detector includes an RF module receiving multiple signals, and a correlator module receiving the signals from the RF module. The correlator module correlates the signals to create a composite ACF, and produces samples of the composite autocorrelation function (ACF). The samples are time delayed relative to each other. The multipath detector also includes a carrier phase processor that receives the samples and estimates carrier phases associated with each of the samples. The carrier phase processor employs the estimated carrier phases to determine if one of the signals is subject to a multipath delay.
