User equipment receives a GNSS signal that includes a GNSS signal from a satellite. The user equipment also receives a first data input from a motion sensor of the user equipment that is indicative of a motion of the user equipment, receives a second data input from the temperature sensor of the user equipment that is indicative of a temperature of the user equipment, and performs a coherent operation based on the pilot channel of the GNSS signal over a coherent period of time based on the first data input and the second data input to generate a resulting signal. The user equipment performs a non-coherent operation based on the resulting signal to amplify the resulting signal, and outputs a position of the user equipment based on the resulting signal.

Dynamic adjustment of coherent signal integration for processing global navigation signals

User equipment (UE) may determine a probability that a cellular network may allocate a resource block to the UE having a frequency that, when a cellular transmitter of the UE transmits a radio frequency (RF) signal using the resource block, a harmonic signal may be generated that interferes with a global navigation satellite systems (GNSS) signal received by a GNSS receiver of the UE. The probability may be determined based on a number of factors that may impact resource block allocation, including a location of the UE, a current date and/or time, a historical allocation of resource blocks (which may be crowdsourced), a client type associated with a signal to be transmitted, a signal environment at the UE, real world conditions, and so on. Based on the probability, the UE may selectively perform a mitigation procedure or transmit an RF signal without performing the mitigation procedure.

Selective cellular interference mitigation for GNSS

Described herein are techniques to enable a mobile device to perform multi-source estimation of an altitude for a location. A baseline altitude may be determined at ground level for a location and used to calibrate a barometric pressure sensor on the mobile device. The calibrated barometric pressure sensor can then estimate changes in altitude relative to ground level based on detected pressure differentials, allowing a relative altitude to ground to be determined. Baseline calibration for the barometric sensor calibration can be performed to determine an ambient ground-level barometric pressure.
