Integer Ambiguity Resolution Analysis of Multi-GNSS Precise Point Positioning
Abstract Compared to the single satellite system, the multi-GNSS could improve the visible satellites’ geometry distribution outstandingly, and further enhance the reliability of ambiguity resolution. This article analysis the products and methods used in PPP ambiguity resolution (PPP-AR) which provided by analytic centers. Then corresponding experiments are conducted to verify the performance of multi-GNSS PPP-AR. It turns out that satellites orbit products provided by analytic centers are highly consistent, and these could provide a better precision datum for PPP. This could accelerate the process of PPP-AR, and also enhance the positioning accuracy when the initial fixed of PPP-AR.
