Abstract

Abstract:

When the base of network RTK is too long, ionospheric delay in the region will weaken. A model of ionospheric delay correction in RTK region is proposed. Firstly, ionospheric delay is calculated based on the known carrier value and the determined non-difference reference ambiguity, and then send rover, finally ionospheric delay is interpolated, get ionospheric delay correction. Through measured CORS data, the results are shown that the algorithm make wide range RTK achieve the cm level results.
