The modernized GNSS transmit more signals on various frequencies to suit different application scenarios. However, for a long time, ambiguity resolution has been available to PPP users only on a few signal frequencies specified by the PPP service provider, which prevents other signal frequencies from being used for high-precision positioning ...

Three Carrier Ambiguity Resolution: Distance-Independent Performance Demonstrated Using Semi-Generated Triple Frequency GPS Signals [PDF]
GPS Solutions, 2010 In spite of significant research in the development of efficient algorithms for three carrier ambiguity resolution, full performance potential of the additional frequency signals cannot be demonstrated effectively without actual triple frequency data. In

Instantaneous ambiguity resolution for URTK and its seamless transition with PPP-AR
GPS Solutions, 2014We extend the current Undifferenced network RTK (URTK) approaches by additionally using P1/CA augmentation information from reference stations. P1/CA augmentation information can shorten the convergence time and help to fix the ionosphere-free combination ambiguities in several epochs.
