摘要： Techniques for supporting positioning with differential corrections are described. In an aspect, differential correction for a satellite may include (i) a user differential range error (UDRE) indicating an uncertainty in a pseudo-range correction for the satellite, (ii) a UDRE growth rate, which may be a scaling factor for the UDRE, and (iii) a time of validity for UDRE growth rate, which may be a time unit used to apply the scaling factor. In one design, a terminal may send a request message to ask for differential correction information and may receive a response message. The terminal may obtain differential correction (e.g., a UDRE, a UDRE growth rate, and a time of validity for UDRE growth rate) for each of at least one satellite from the response message. The terminal may derive a location estimate for itself based on the differential correction for each satellite.

摘要： A mobile communications device uses a method for determining position that involves a positioning filter, such as a Kalman filter, which is initialized with measurements from reference stations such as satellite vehicles and/or base stations which may be acquired during different epochs. Accordingly, the positioning filter may be used for position estimation without the need to first acquire at least three different signals during the same measurement epoch.

摘要： Systems, apparatuses, and/or methods are provided for resolving ambiguities associated with signals received from space vehicles (SVs) in a satellite navigation system. For example, certain methods include receiving a first SV signal from a first satellite positioning system (SPS), and reducing a bit edge ambiguity of a data signal modulating a second SV signal received from a second SPS based, at least in part, on information in the received first SV signal.
