Abstract: Systems, methods, apparatuses and computer-readable storage mediums are disclosed for device state estimation under periodic motion. In some implementations, a method comprises: detecting, by a device, periodic motion from a sensor signal generated by a sensor of the device; generating, by the device, a trigger signal or schedule based on the detecting; generating, by the device, a periodic motion constraint update in response to the detecting; and updating, by the device and in response to the trigger signal or schedule, an estimated state of the device using the periodic motion constraint update.

Abstract: Systems, methods, and computer program products for determining a location from non-line-of-sight (NLOS) signals are described. A processor can determine that multipath interferences of a signal reaching a receiver through different paths that are close in lengths may be mistakenly interpreted as additional time shift, (e.g., additional time delay or, in some cases, time advance) of the signal in calculating a timing of the signal. The processor can determine the possible differences between path lengths and then determine an amount of the additional time shift. The processor can determine a shift correction to remove effects caused by the additional time delay from the timing calculation.

Abstract: Systems, methods, and computer program products for determining a location from non-line-of-sight (NLOS) signals are described. An RF receiver can receive signals of an RF transmitter (e.g., a GNSS satellite) reflected by one or more building surfaces. A processor embedded in or coupled to the RF receiver can reduce the effects of multipath interference caused by the reflections using data on reflective characteristics of buildings located close to the RF receiver. The data can include information on which surfaces of the buildings are visible to the RF receiver. The processor can then estimate, from the visible surfaces and known satellite locations, feasible signal paths for a signal from a satellite to the RF receiver. The processor can then correct a location estimation by taking into account the multipath effects of the signal traveling along the feasible signal paths.

Abstract: Systems, methods and computer program products for determining extended coherent integration intervals based on information about user activity, dynamics and clock stability. Dynamically extending the coherent integration interval increases the signal-to-noise ratio during signal acquisition and tracking, thereby providing a benefit when antenna gain is poor, in weak signal conditions, and when being jammed, or when power needs to be conserved, compared to extending the coherent integration interval for a fixed amount of time.

Abstract: Embodiments described herein provide for a system, a non-transitory machine-readable medium, and methods to provide location services. In an embodiment, a method provides receiving at least one indication that an electronic device is in transit to at least one defined location, establishing a first fence boundary for the at least one defined location, receiving an indication that the electronic device has crossed the first fence boundary and is in transit to a defined location, and establishing a second fence for the defined location, where the second fence provides a finer granularity fence for the defined location than the first fence.
