Abstract: Apparatuses and methods of manufacturing same, systems, and methods are described for combining received and correlated Global Navigation Satellite System (GNSS) signals and using the combined signal for improving GNSS reception in, inter alia, challenging environments. In one aspect, a first correlated GNSS signal and a second correlated GNSS signal are stored and then combined, and the combined signal is used to adjust reception of the first GNSS signal and/or the second GNSS signal. If the first and second correlated GNSS signals are stored by unequal time periods, time periods of one or both are added together until the total added first correlated GNSS signal is the same length of time as the total added second correlated GNSS signal. In order to properly combine the GNSS signals, gain/balancing factor(s) may be applied, the polarity of one or both may be flipped, etc.

Abstract: A Global Navigation Satellite System (GNSS) receiver includes a wideband signal correlator and a multipath mitigator. The wideband signal correlator generates wideband correlation signals of at least one of a plurality of GNSS signals with respect to corresponding locally generated code replica signals in which a bandwidth of the wideband signal correlation module is at least about 20 MHz. The multipath mitigator determines a Line of Sight (LOS) signal from the wideband correlation signals. The GNNS receiver may include a narrowband signal correlator to generate narrowband correlation signals of the at least one GNSS signal with respect to corresponding locally generated code replica signals in which a bandwidth of the narrowband signal correlation module is less than about 6 MHz. The multipath mitigator further corrects a range and range-rate measurement generated from the narrowband correlation signals based on a code phase and a carrier estimated based on the LOS signal.

Abstract: Methods, systems, and portable devices which reduce the power used by a portable device to receive/process satellite navigational system signals and/or to compute the portable device's position using satellite navigational system signals are described. One portable device retrieves power usage information corresponding to its current location, where the power usage information is based on aggregate data from portable devices which have traversed and/or are traversing the current location. The portable device then selects a power saving mode from a plurality of power saving modes based on the retrieved power usage information, where each power saving mode reduces power usage in one or more of receiving and/or processing satellite navigational system signals, and/or computing the portable device's position using the satellite navigational system signals.

Abstract: A method, receiver, and mobile terminal for simultaneously receiving and processing signals of multiple satellites from a plurality of navigational satellite system constellations are described. In the method, satellite signals from a plurality of navigational satellite systems are translated into an intermediate frequency and converted from analog to digital together, but then are separated out according to each navigational satellite system in the digital domain.

Abstract: A method and an apparatus are provided for improving a carrier to noise density ratio (CNO) of a matched filter. A signal is received at a signal register of the matched filter. A local code is received at a local code register and a nulling register of the matched filter. An adder tree of the matched filter correlates the signal register and the local code register with respect to the nulling register to obtain a correlation result. The nulling register prevents high frequency samples of the signal register from affecting the correlation result.

Abstract: Systems, methods and apparatuses for generating long coherent integrations of received global navigation satellite system (GNSS) signals are described. One method includes generating coherent 1 second I/Q correlations by at least two stages of summation starting with 1 millisecond correlated I/Q signal samples. Intermediate stage coherent I/Q correlations may be modified based on, for example, lack of carrier phase lock and/or the carrier signal-to-noise density (C/No). Such modifications include phase rotation. Energy/power amplitudes calculated from the coherent 1 second I/Q correlations may be used for improving multipath mitigation, the signal-to-noise ratio (SNR), and other GNSS receiver operations and functions.

Abstract: Systems, methods and apparatuses for multipath mitigation of received global navigation satellite system (GNSS) signals by using pattern recognition are described. One method includes summing correlations of received GNSS signals over time to generate a correlation window. The present system/method recognizes a pattern of a stored correlation window which matches the generated correlation window. The stored correlation window is one of a plurality of stored correlation windows, and each of the plurality of stored correlation window is stored with a corresponding range error. The stored range error corresponding to the matching stored correlation window is used to improve GNSS range measurement.

Abstract: Apparatuses, systems, and methods for mitigating the effects of null zones on the measurements of Global Navigation Satellite System (GNSS) receivers are described. In one aspect, a GNSS receiver calculates both a filtered value of an integrated and summed value for a punctual correlator of a satellite signal (“the calculated filtered punctual correlator value”) and an average of integrated and summed correlator values for a plurality of noise/offset correlators of the satellite signal (“the calculated average noise/offset correlator value”). The GNSS receiver then calculates a signal energy loss parameter ESL of the satellite signal using the calculated filtered punctual correlator value and the calculated average noise/offset correlator value and processes the satellite signal measurement based at least on the signal energy loss parameter ESL and a predetermined threshold ThSL presently corresponding to the punctual and noise/offset correlators of the satellite signal.
