    Abstract: Techniques are provided which may be implemented using various methods and/or apparatuses in a mobile GNSS device to compensate for arm swing. An example of an method for compensating for arm swing according to the disclosure includes determining an arm swing signal, such that the arm swing signal is approximately sinusoidal with a period of approximately T seconds, determining a position signal measurement period, receiving a plurality of positioning signals at intervals corresponding to the position signal measurement period, and determining current position information based on the plurality of positioning signals.

    Abstract: Methods, systems, computer-readable media, and apparatuses for determining a flight route for a flight of an unmanned aerial vehicle (UAV) are presented. The flight-specific route for the UAV is determined dynamically during the flight or in advance before the flight, using navigation assistance data that includes flight-specific navigation assistance data for a plurality of geographic zones determined based on flight-specific information. The flight-specific navigation assistance data includes flight-specific ranking data for the plurality of geographic zones that can be used by the UAV or a server to determine the flight route.

    Abstract: Disclosed is a method and apparatus for correcting clocks for a plurality of local transmitters. In one embodiment, the functions implemented include: receiving base station time from a plurality of local transmitters; assigning each local transmitter of the plurality of local transmitters to at least one subset of a plurality of subsets, wherein each subset corresponds to a single base station, and wherein each local transmitter in a particular subset receives time from a base station corresponding to the subset; selecting a single subset of local transmitters as a reference subset of local transmitters, the reference subset corresponding to a reference base station, each non-reference subset corresponding to a non-reference base station; determining a time difference between the reference base station and each of the non-reference base stations based on time received from one or more local transmitters that belong in more than one of the subsets; and transmitting the time difference to respective non-reference subsets of local transmitters.
