Abstract: An attenuated satellite positioning system (SPS) signal is acquired using long integration over multiple navigation data bits. To produce a stable internal clock signal to perform the long integration, an external clock signal is received from a highly stable source, such as a wireless communication base station or a nearby femtocell. An internal oscillator is driven at a desired frequency that is aligned with the scaled frequency of the external clock signal to produce the stable internal clock signal. The SPS signal is received and integrated for an extended period using the internal clock signal. Predicted SPS data may be received from an external source and used to perform coherent integration. Alternatively, non-coherent integration may be performed. Additionally, a motion sensor may be used to determine if there is motion relative to the external clock source or to compensate for Doppler errors in the external clock signal due to motion.

Abstract: Systems, apparatus and methods for a mobile device and a base station almanac server to throttle crowdsourcing information are presented. The crowdsourcing information is used to improve a location of a base station in a base station almanac. A portion of the base station almanac is provided to a mobile device. For example, the mobile device may identify its current cell and request the base station almanac. The mobile device records crowdsourcing information to identify, for each particular base station of at least one base station, a cellular identifier for the particular base station, optional ranging information between the particular base station and the mobile device, and an independent position of the mobile device. The independent position of the mobile device may be formed from global navigation satellite system (GNSS) or station signals independent of the at least one base station.

Abstract: Disclosed are methods, systems and/or devices to calibrate a network time by acquisition of satellite positioning system (SPS) signals and different instances of time, and time-tagging SPS times according to the network time. In particular, the network time may be calibrated based, at least in part, on a first difference between first and second SPS times obtained at two SPS position fixes and a second difference between corresponding first and second time stamps.

Abstract: A method for maintaining timing accuracy in a mobile device includes: obtaining a range estimate using a signal received from a timing information source via a communication unit of the mobile device; obtaining position and velocity estimate information for the mobile device from a source of position and velocity information separate from the timing information source, the position and velocity estimate information being obtained from at least one sensor of the mobile device, or via a communication unit of the mobile device using a Vehicle-to-Everything wireless communication protocol, or a combination thereof; determining estimated clock parameters based on the position and velocity estimate information and the range estimate; and adjusting a clock of the mobile device based on the estimated clock parameters in response to a position-and-velocity-assisted timing uncertainty corresponding to the estimated clock parameters being below a timing uncertainty threshold.

Abstract: A multipath (MP) carrier phase detector is disclosed that uses phase differences in the output of Early/Prompt/Late (EPL) correlation for MP detection. Embodiments may take coherent integrations of EPL correlator outputs and determine the respective carrier phase of each output. Phase differences can then be computed, and integer cycles and biases can be removed. MP can then be identified if a maximum phase difference of the EPL correlator outputs are determined to be above a certain threshold. According to some embodiments, false positives may be reduced by averaging phases and/or phase differences over a plurality of samples, and/or if a threshold number of consecutive MP detections have been made.
