Abstract: In some implementations, an apparatus may receive a request for the Global Navigation Satellite System (GNSS) position fix information. The request may include an accuracy requirement. The apparatus may determine a set of GNSS bands to use to determine the GNSS position fix information. The set of GNSS bands may comprise one or more bands from a plurality of available GNSS bands, and determining the set of GNSS bands to use may be based at least in part on the accuracy requirement. The apparatus may determine the GNSS position fix information based at least in part on GNSS signals received via the selected set of GNSS bands. The apparatus may provide the GNSS position fix information (e.g., to an application processor). The GNSS position fix information may comprise a GNSS position fix, pseudorange information, or both.

Abstract: A satellite signal method includes: receiving a satellite signal at an apparatus; transmitting, from the apparatus, one or more outbound signals; and inhibiting processing, by the apparatus, of at least a first portion of the satellite signal spanning a first frequency set that includes at least a portion of an interference signal corresponding to transmission of the one or more outbound signals.

Abstract: A mobile device may be configured to perform concurrent Satellite Positioning System (SPS) operation and wireless communications when uplink signals transmitted by the mobile device interferes with the reception of SPS signals in one or more frequency bands. The mobile device may determine if the SPS receiver has already acquired SPS signals and is in a tracking state. If the SPS receiver is not in a tracking state, an SPS acquisition procedure is initiated before the wireless communication session is initiated. The SPS acquisition procedure is performed until the SPS receiver reaches a tracking state, or until a timeout is reached. Once the SPS receiver is in a tracking state, the wireless communication session may be initiated, during which the SPS receiver is controlled, e.g., to perform signal blanking, measurement exclusion, or disable SPS reception, to mitigate interference with SPS signals.

Abstract: Described herein are systems and techniques for mitigating the impact of attenuated satellite signals received at mobile devices. A mobile device receives multiple signals from a single satellite on different carrier frequencies. The mobile device calculates two pseudorange measurements, each pseudorange measurement from a different signal of the multiple signals. The mobile device calculates the difference between the two pseudorange measurements, and if the difference exceeds a first threshold and the first pseudorange measurement is larger than the second pseudorange measurement, the mobile device marks the first pseudorange measurement as impaired. If the difference exceeds a second threshold and the second pseudorange measurement is larger than the first pseudorange measurement, the second pseudorange measurement is marked as impaired. The impaired measurements may be weighted or excluded from use in calculating a position of the mobile device or in another pseudorange measurement based calculation.

Abstract: In conditions in which Global Navigation Satellite System (GNSS) signal spoofing is likely occurring, a GNSS receiver may be operated in a reduced operational state with respect to one or more GNSS bands that are likely being spoofed. According to embodiments, a reduced operational state with regard to a GNSS band may comprise performing one or more of the following functions with respect to that GNSS band: disabling data demodulation and decoding, disabling time setting (e.g., time of week (TOW), week number, etc.) disabling acquisition of unknown/not visible satellites, disabling satellite differences, disabling error recovery, reducing non-coherent integration time, and duty cycling the power for one or more receiver blocks associated with the GNSS band.

Abstract: An apparatus control method includes: controlling a first frequency band receive chain, of an apparatus, to alternate being on and off with a first duty cycle, the first frequency band receive chain being configured to measure satellite signals within a first frequency band; determining one or more performance criteria; and controlling, based on the one or more performance criteria, a second frequency band receive chain, of the apparatus, to alternate being on and off with a second duty cycle, the second frequency band receive chain being configured to measure satellite signals within a second frequency band.

Abstract: A method for inhibiting jammed signal use includes: receiving a desired signal wirelessly at a receiver; receiving an undesired signal wirelessly at the receiver, the undesired signal varying in strength over time; and inhibiting measurement of the desired signal, or use of a measurement of the desired signal, based on a determination that the undesired signal is a jamming signal based on a variation of the undesired signal being indicative of jamming.
