Abstract: A method implemented by an assisted Global Navigation Satellite System (GNSS) server determines a position of a GNSS receiver. The method includes sending a request for measurement information to the GNSS receiver at a first time and receiving the measurement information from the GNSS receiver in response to the request at a second time, where the measurement information includes position measurement data and a corresponding measured time based on satellite signals received by the GNSS receiver. The measured time is determined to be erroneous when it is outside an accurate time range determined based on at least one of the first time and the second time. A substitute time is identified and the position of the GNSS receiver is determined based on the substitute time when the measured time is erroneous.

Abstract: A system and method for determining a location of a wireless device in a communications network. A request for satellite assistance data may be received from a requesting entity, and a reference location determined as a function of the request. One or more characterizing attributes may be identified as a function of the reference location, and a set of satellites determined as a function of the reference location. It may also be determined whether more than one set of signal measurements should be acquired from one or more satellites in the set of satellites as a function of the identified one or more characterizing attributes. The one or more sets of signal measurements may be acquired, and a location of the wireless device determined from the acquired measurements.
