Abstract
AbstractHigh-precision (centimeter-level) real-time kinematic precise point positioning (PPP-RTK) becomes feasible when using precise corrections, as received from a regional Continuously Operating Reference Station network. These network corrections comprise (biased) satellite clocks, (biased) satellite phase biases, and ionospheric delays, where the latter ones are interpolated to the approximate location of the PPP-RTK receiver. Thus far, very fast PPP-RTK integer ambiguity resolution performance has been reported based on dual-frequency Global Positioning System (GPS) data. The availability of ionospheric corrections enables one to carry out PPP-RTK using a single-frequency receiver. Despite that single-frequency integer ambiguity resolution based on a single epoch of data cannot often be successful, fast integer ambiguity resolution is possible when accumulating a short time span of data, assuming that the ambiguities are time constant. In this paper, results of the performance of single-frequency PP...
