A system and method for providing improved correction information to navigation receivers includes receiving, from a plurality of reference stations at known locations, a plurality of satellite navigation measurements of signals from a plurality of global navigation satellites. A state of the plurality of global navigation satellites is computed based on the received satellite navigation measurements. Baselines, each corresponding to a pair of the reference stations, are identified. For each identified baseline, computing floating and integer values for a double-differenced integer ambiguity. Double-differenced integer ambiguities that satisfy a set of predefined conditions are identified, and the computed state of the plurality of global navigation satellites is adjusted in accordance with an integer value constraint applied to each double-differenced integer ambiguity that satisfies the set of predefined conditions. The correction information is computed from the adjusted computed state of the plurality of global navigation satellites.

A wireless device determines a biased wireless device position and a receiver clock error for a plurality of satellites, the biased wireless device position and the receiver clock error being associated with a biased ambiguity. The wireless device calculates, upon determining the biased wireless device position and the receiver clock error, the biased ambiguity for each of the plurality of satellites. The wireless device applies the biased ambiguity to a carrier phase measurement for each of the plurality of satellites, the carrier phase measurement being associated with the receiver clock error and an absolute location of the wireless device. The wireless device determines, upon applying the biased ambiguity to the carrier phase measurement for each of the plurality of satellites, the absolute location of the wireless device based on the biased ambiguity for all of the plurality of satellites.

A Precise Point Positioning (PPP) system is disclosed in which one or more Global Navigation Satellite System (GNSS) signals are obtained by a mobile device. The mobile device can obtain position information based on one or more position sources, where the position information is indicative of a location of the mobile device. One or more PPP positions of the mobile device can be determined based on the position information and the one or more GNSS signals, where a position uncertainty of the position information meets or is below an uncertainty threshold. A determination of whether at least one PPP position meets or is below one or more convergence thresholds can be made. In response to determining that at least one PPP position meets or is below the one or more convergence thresholds, the at least one PPP position can be provided.

An Real-Time Kinematic (RTK) and/or Differential GNSS (DGNSS) system is disclosed in which correction data from a plurality of reference stations is provided to the mobile device. A selection of reference stations (from which correction data is provided to the mobile device) can be made based on factors such as the approximate location of the mobile device, geometry of the reference stations, and/or other factors. The mobile device can combine the correction data from the plurality of reference stations in different ways to determine an accurate position fix for the mobile device, without interpolating correction data from the plurality of reference stations.

Described are methods, systems, and devices for determining position using Differential Global Navigation Satellite (DGNSS) measurements. Techniques described herein involve taking carrier phase measurements at a reference station or other GNSS receiver at a known location, and combining the carrier phase measurements with pseudorange measurements taken at the reference station to resolve carrier phase ambiguity and to, in combination with pseudorange measurements taken at a mobile device, obtain a differentially corrected measurement that can be used to estimate a position of the mobile device. The differentially corrected measurement can be a double differential measurement based on signals from a pair of GNSS satellites.

Embodiments described herein provide for enabling a mobile device comprising a GNSS receiver to implement a modified PPP technique that utilizes orbit and clock information of a satellite that is broadcast from the satellite. In particular, embodiments may utilize a positioning engine to perform PPP error mitigation with respect to various error sources (e.g., troposphere, ionosphere, phase windup, etc.). With regard to errors stemming from satellite orbit and satellite clock, embodiments may utilize orbit and clock information from broadcast ephemeris data rather than obtaining precise orbit and clock information (e.g., from a third party provider). Further, embodiments may account for errors in this broadcast information by adjusting the ambiguity dynamic and/or ambiguity estimate term used by the positioning engine. This can enable the positioning engine to determine a solution more accurate than traditional GNSS without resetting.

Methods and systems for performing Precise Point Positioning (PPP) ambiguity resolution using Global Navigation Satellite Systems (GNSS) triple frequency signals are described. In an embodiment, the method may include computing, using a processing device, an L1/L2 or L2/L5 wide-lane fractional bias model, in which the bias is split into one direction-independent and three direction-dependent bias components for each satellite. Additionally, the method may include resolving, using the processing device, PPP ambiguity using triple-frequency signals. The method may also include applying, using the processing device, a carrier smooth carrier function to resolve measurement noise. Resolving the PPP ambiguity may include fixing the L2/L5 wide-lane ambiguities in a geometry-free function. Additionally, resolving the PPP ambiguity may include fixing the L1/L2 wide-lane ambiguities in a geometry-based function. Similarly, resolving the PPP ambiguity may also include fixing the L1/L5 wide-lane ambiguities in a geometry-based function.
