Abstract: Certain aspects of the present disclosure provide techniques reducing wireless interference in wireless communications networks by, for example, enabling a coexistence period during which transmission over a first wireless communication band is deprioritized and reception over a second wireless communication band, different from the first wireless communication band, is prioritized; and receiving positioning data from a positioning system via the second wireless communication band during the coexistence period.

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 method of determining a location of a mobile device in the presence of a spoofing signal includes obtaining current position information associated with the mobile device, determining a Global Navigation Satellite System (GNSS) signal search window for acquiring GNSS signals associated with a satellite based on the current position information, searching a GNSS signal associated with the satellite based on the GNSS signal search window, and determining updated position information of the mobile device based on at least information of the GNSS signal associated with the satellite.

Abstract: A method of detecting an anomalous SPS signal includes determining whether a first SPS signal is anomalous by determining: whether an actual SPS signal measurement difference is consistent with an expected measurement difference; whether a received power of the first SPS signal exceeds a maximum expected power; whether the first SPS signal originated from an SV location consistent with first SV location information; whether a first pseudorange to a first SV differs by more than a first pseudorange threshold from an expected pseudorange; that a first location, based on the first SPS signal measurement corresponds to at least one of an unexpected location or a high likelihood of anomaly location; whether one or more base station signal measurements are consistent with a first SPS signal measurement; and/or whether a measured signal quality of the first SPS signal is consistent with an expected signal quality.

Abstract: A Real-Time Kinematic (RTK) solution is provided to mobile devices having multi-constellation, multi-frequency (MCMF) functionality, in which a single base station may have a baseline much farther than traditional base station. To enable this, embodiments account for differences in atmospheric effects between the rover station and base station when determining a GNSS position fix for a mobile device (rover station), allowing for a separate tropospheric delay error for a base station to be determined. Embodiments may use additional satellite measurements for which no RTK correction is available, and may further use orbital clock correction for these additional satellite measurements.

Abstract: Embodiments herein provide for a Low-Frequency (LF) broadcast system that improves on the LORAN-C system to help optimize the use of available spectrum while modernizing the signal structure of broadcast signals. In particular, embodiments can utilize an Orthogonal Frequency Division Multiplexing (OFDM) signal structure to broadcast timing and data signals in successive symbols of an OFDM resource block. Signals can include, for example, comb-1, comb-2, or comb-3 signal structures. Other signal aspects such as muting schemes, modulation, frequency offsets, and the like may vary, depending on desired functionality

Abstract: Aspects presented herein may improve the positioning accuracy and latency of a positioning engine that receives at least one position constraint for assisting the positioning. A wireless device obtains an indication of at least one position constraint for a positioning engine. The wireless device detects whether the at least one position constraint exceeds an error threshold based on a set of PR residuals between the wireless device and at least one satellite. The wireless device excludes the at least one position constraint from a calculation at the positioning engine if the at least one position constraint exceeds the error threshold, or includes the at least one position constraint in the calculation at the positioning engine if the at least one position constraint is below the error threshold.

Abstract: A wearable device that can receive a plurality of Global Navigation Satellite System (GNSS) timing signals using an antenna, where the antenna is located in an exterior portion of the wearable device such that the antenna receives GNSS signals at the external portion of the wearable device, without the GNSS signals first passing through an air gap within a housing of the wearable device. The wearable device is configured to determine a geographic location of the wearable device based at least in part on the GNSS signals. The wearable device is configurable to perform underwater dead-reckoning procedures, measuring energy levels during dwell periods, measuring efficiency of swim strokes, sharing wearable device information with other electronic devices, calibrating the wearable device, or a combination thereof.

Abstract: Determining a boundary of a spoofing region identifying spoofed satellite signals may comprise determining, based on a first set of Global Navigation Satellite System (GNSS) signals received at a GNSS receiver over a first period of time, at least one GNSS signal corresponding to a GNSS satellite has experienced a first transition, wherein the first transition comprises a transition from a not spoofed state in which the at least one GNSS signal is not determined to be spoofed to a spoofed state in which the at least one GNSS signal is determined to be spoofed, or a transition from the spoofed state to the not spoofed state. Additionally, a first location corresponding to a location at which the GNSS receiver was located during the first transition may be determined.
