| Abstract | : A linear combination functional model, formed from the single-differenced functional equation for baselines from a roving GPS receiver to three or more reference receivers, is proposed. In this model, the orbit bias and ionospheric delay can be eliminated, and the tropospheric delay, multipath, and observation noise can be significantly reduced. As a result, the ambiguity resolution technique that can be employed for medium-range GPS kinematic positioning is similar to that used for the short-range case. Kinematic tests have been carried out in Sydney, Australia, with distances from the nearest GPS reference stations of more than 30 km. The carrier-phase ambiguities could be resolved for every epoch with just a single epoch of data, and the success rate (correct identification of the integer ambiguities) was 100 percent. This technique is well suited to real-time precise GPS kinematic positioning. |
