    Abstract: A method of determining a location of a measurement device includes determining, at a server: measurement times of first positioning signal measurements, of first positioning signals from first positioning signal sources and/or a subset of positioning signal sources of second positioning signal sources. The method includes sending at least one measurement command from the server to the measurement device to cause the measurement device to obtain the first positioning signal measurements in accordance with the measurement times and/or obtain second positioning signal measurements of second positioning signals sent from the subset of positioning signal sources. The method includes: receiving, at the server from the measurement device, measurement data corresponding to the first positioning signal measurements and/or the second positioning signal measurements; and determining, at the server, the location of the measurement device based on the measurement data.

    Abstract: Techniques described herein leverage multi-constellation, multi-frequency (MCMF) functionality to provide a local Real-Time Kinematic (RTK) solution for a mobile device in which an initial highly-accurate location determination for the mobile device can be leveraged to generate RTK correction information that can be used to make subsequent, highly-accurate location determinations without the need for measurement information from an RTK base station. This RTK correction information can be applied to Global Navigation Satellite System (GNSS) measurements taken by the mobile device over a long period of time while retaining the ability to produce highly-accurate location determinations for the mobile device. And additional correction information may be obtained and applied to the RTK correction information to extend this period of time even longer.

    Abstract: Methods for mobility indication of wireless Access Points (APs) are disclosed. An AP may determine mobility indication information, based, in part, on at least one of: configuration information on the AP pertaining to mobility; and/or wireless signal measurements associated with the AP, and/or captured images associated with the AP, and/or sensor measurements associated with the AP. The AP may transmit the mobility indication information for the AP. The mobility indication information may indicate that the AP is mobile and/or characterize the mobility. The mobility indication information may further include a request to remove information associated with the AP from location determination databases, location assistance databases, and/or base station almanacs. Disclosed methods also pertain to a User Equipments (UE), which may receive wireless signals with mobility indication information associated with an AP; and determine a suitability of the AP for determining the UEs location based on the received mobility indication information.

    Abstract: Disclosed are methods, systems and devices for providing location based services in a venue. To estimate its location, in a particular implementation, a mobile device may obtain a measurement of a range to a transponder device positioned at a known location based on measurements of a signal round-trip time (RTT) in a message exchange with the transponder device. Positioning assistance data from a server may enable the mobile device to measure a delay at the transponder device in providing a response to a probe message to thereby more accurately measure the signal RTT.
