Abstract: In some implementations, the disclosed techniques may include tuning a first antenna element to a first tuning state during an acquisition mode for establishing communication channels with satellites. The first tuning state can configure the first antenna element to receive signals in a first frequency range. The techniques may include establishing the communication channels using the first antenna element in the first tuning state during the acquisition mode. The techniques may include transitioning from the acquisition mode to a tracking mode. The techniques may include changing the tuning state of the first antenna element. The techniques may include determining a location of the mobile device during the tracking mode: (1) using the first antenna element and a second antenna element of the mobile device or (2) not using the first antenna element and using the second antenna element that is configured to receive signals in a second frequency range.

Abstract: User equipment detects interference with a global navigation satellite system (GNSS), as well as a time of when the interference occurs. The user equipment also receives a transmission time offset associated with the interference. In some embodiments, the user equipment determines a boundary of a frame based on the transmission time offset and the time of when the interference occurs. The user equipment then communicates with a non-terrestrial network based on the frame. Additionally or alternatively, the user equipment determines whether the time of when the interference occurs aligns with a frame cycle of the frame. If so, then the user equipment provides an indication of the interference or guidance to reduce or avoid the interference.

Abstract: Methods, non-transitory machine-readable mediums, and system to provide location services are described. In an embodiment, a method provides receiving at least two position fixes for a trajectory of an electronic device, where the at least two position fixes are obtained intermittently, matching the at least two position fixes to points on a path indicated in map data, and computing a distance for the trajectory using distance information using the map data.
