A New Ambiguity Resolution Method for PPP Using CORS Network and its Real-time Realization modeling the code UD observation residual. Thus rover could obtain more accurate approximate coordinate by code Single Point Positioning (SPP), and then, speeding up the ambiguity convergence time. In addition, based on the improved URTK method, a three-step method for single-differenced (SD) ambig

Ionosphere-Free Combinations for Triple-Frequency GNSS with Application in Rapid Ambiguity Resolutioe-frequency ionosphere-free combinations in ambiguity resolution and precise positioning is analyzed. The analytical expression of linear coefficients of them is deduced, and the influences of various errors on ambiguity resolution and precise positioning are evaluated. Considering that the waveleng

Preliminary Analysis of Real-Time Orbit and Clock Error Based on BNCoadcast ephemeris and orbit/clock corrections was retrieved real time, and real-time orbit and clock product with high precision was obtained. Preliminary analysis was conducted among results with different broadcasters, which prepare for real-time PPP.

Martin Torriani,Daniel I. Rosenthald of code is suitable for channel coding scheme of navigation data of COMPASS. This paper analyzes the cycle structure of QC-IRA-B codes based on circulant permutation matrices. The analysis of this paper shows that some special cycle structures result in lots of low-weight code words which worsen t
