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 jamming signal detection control method includes: receiving, at a satellite positioning signal receiver, one or more satellite positioning signals; determining, at the satellite positioning signal receiver, one or more quality metric values based on the one or more satellite positioning signals; determining, at the satellite positioning signal receiver, whether the one or more quality metric values are indicative of jamming; and activating, at the satellite positioning signal receiver and in response to the one or more quality metric values being indicative of jamming, a jammer detection technique to determine whether a jamming signal is received by the satellite positioning signal receiver.

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: Techniques for managing power consumption of a Global Navigation Satellite System (GNSS) receiver of a mobile device are provided. These techniques include a method that includes deriving a GNSS search window for the GNSS receiver based on a position uncertainty (PUNC) and a time uncertainty (TUNC), selecting a GNSS search mode based on the GNSS search window and resources available for searching for signals from GNSS satellite vehicles (SVs), wherein an estimated power consumption associated with execution of a GNSS search associated with the GNSS search mode does not exceed a power consumption limit specified for the GNSS receiver conducting the GNSS search using the GNSS search mode, and estimating a position of the mobile device.

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.

Abstract: In some aspects, a mobile device is configured to obtain a set of satellite signal measurements through measuring, for each satellite in a first plurality of satellites, a first signal from the satellite in a first frequency band and a second signal from the satellite in a second frequency band. The first plurality of satellites can include at least a first satellite, a second satellite, and a third satellite. The mobile device can determine that at least one measurement in the set of satellite signal measurements is impaired, based on a difference between a measurement of the first signal from a particular satellite (e.g., the first satellite, the second satellite, or the third satellite) and a measurement of the second signal from the particular satellite. A position of the mobile device can then be determined based on non-impaired measurements in the set of satellite signal measurements.
