Fast convergence of Trimble CenterPoint RTX by regional
a regional ionosphere modeling and rapid convergence approach to improve SF PPP (SFPPP) accuracy and accelerate DF PPP (DFPPP) convergence speed. Instead of area model, ionospheric delay is modeled for each satellite to be used as a priori correction.... A Powerful Technique with a Promising Future Precise Point Positioning more than 10 years ago in an Innovation column, I wrote, “Although RTK is the latest word, or should we say acronym, in GPS positioning, it will not be the last. Scientists and engineers will continue to invent faster, more accurate, more convenient, and more reliable ways to use GPS in navigation, surveying, and a host

Innovation Examining precise point positioning now and in
Toggle Toolbox... Finally, the atmospheric corrections are introduced in PPP-RTK as a priori values to allow improvements in ambiguity fixing and to reduce its convergence time. The discussion emphasizes the positive and the negative points of each solution or even the associated use of them.

A Powerful Technique with a Promising Future UNB
Real-time single frequency precise point positioning (PPP) is a promising technique for high-precision navigation with sub-meter or even centimeter-level accuracy because of its convenience and low cost. The navigation performance of single frequency PPP …...

• Use of Global and Regional Ionosphere Maps 761 model mapping function is used. For the computation of the ionospheric pierce points, a spherical layer
• The PPP convergence time and positioning accuracy using the RTS products is estimated and compared with dual frequency PPP and single-frequency PPP obtained through the combined rapid IGS Global Ionospheric Maps (IGS-GIM) over three consecutive days under high solar activity and one of them under active geomagnetic activity. The results show that the proposed model improves PPP …

• In this paper, the impact of the quality of ionospheric models on the convergence of IC-PPP is evaluated using the IGS global ionospheric map (GIM) updated every two hours and a regional satellite-specific correction model. Furthermore, the effect of the receiver differential code bias (DCB) is investigated by comparing the convergence time for IC-PPP with and without estimation of the DCB
