Abstract
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.
