Abstract: A mobile device may be configured to improve measurement of carrier phase (CP) in received satellite signals for satellite positioning system (SPS) operations. For example, this may enable an SPS receiver to measure CP of at least a first positioning signal of a first frequency band and a second positioning signal of a second frequency band each received from the same satellite vehicle. A corrected CP of the first positioning signal may be estimated based on the measured CP of the first positioning signal and on the measured CP of the second positioning signal.

Abstract: An apparatus includes: a transceiver configured to receive a satellite signal and to transmit one or more outbound signals; a memory; and a processor, communicatively coupled to the transceiver and the memory, configured to: transmit, via the transceiver, the one or more outbound signals; blank 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 by the transceiver; and process a second portion of the satellite signal spanning a second frequency set that includes no frequencies of the interference signal; wherein the first frequency set and the second frequency set are different frequency portions of a same time portion of the satellite signal.

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: 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.

Abstract: Techniques are provided for utilizing notch filters to overcome narrowband jamming. An example method for determining a range to a satellite vehicle with a receiver includes receiving a signal from the satellite vehicle, determining one or more notch filter configurations, determining a pseudorandom noise code and a doppler frequency associated with the signal, determining a codephase correction value based at least on the one or more notch filter configurations, the pseudorandom noise code and the doppler frequency, and computing the range to the satellite vehicle based at least in part on the signal and the codephase correction value.
