Improving DGNSS Performance through the Use of Network RTK Corrections

The differential global navigation satellite system (DGNSS) is an enhancement that widely used to improve the accuracy of single-frequency receivers. However, distance-dependent errors are not considered in conventional DGNSS, and DGNSS decreases when baseline length increases. In network real-time kinematic (RTK) positioning, accurately modelled enable ambiguity resolution on user side, standard Radio Technical Commission for Maritime Services (RTCM) formats have also been developed describe spatial characteristics errors. RTK service was mainly carrier-phase measurements professional purpose this study modify local-area through use corrections. Distance-dependent can be reduced, a longer improved. results low-latitude areas showed modified could improved by more than 50% 17.9 km during solar active years. method paper extends available corrections with high normal applications.
