Towards PPP-RTK: Ambiguity resolution in real-time precise point positioning [PDF]
Advances in Space Research, 2010 Abstract Integer ambiguity resolution at a single station can be achieved by introducing predetermined uncalibrated phase delays (UPDs) into the float ambiguity estimates of precise point positioning (PPP). This integer resolution technique has the potential of leading to a PPP-RTK (real-time kinematic) model where PPP provides rapid convergence to a

A-PPP: Array-Aided Precise Point Positioning With Global Navigation Satellite Systems
IEEE Transactions on Signal Processing, 2012 In this paper, the global navigation satellite system (GNSS) precise point positioning (PPP) concept is generalized to array-aided PPP (A-PPP). A-PPP is a measurement concept that uses GNSS data, from multiple antennas in an array of known geometry, to realize improved GNSS parameter estimation (position, attitude, time and atmospheric delays).
