Towards PPP-RTK: Ambiguity resolution in real-time precise point positioning [PDF]
Advances in Space Research, 2011 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
