Analysis of GPS-DCM Clock Corrections in Support of 1Hz PPP-AR Applications

The International Technical Meeting of the The Institute of Navigation, 2019
Decoupled-Clock Model (DCM) improves the accuracy of Precise Point Positioning (PPP) by enabling Ambiguity Resolution (AR). Clock and bias corrections are typically estimated at 30-seconds rate to reduce the computation time. However, high rate PPP-AR applications, typically use 1 Hz tracking data, and ideally require 1-s clock corrections. The quality

Improved multi-GNSS PPP-AR performance through refined tropospheric and multipath models

Tropospheric delay and multipath effect are two key errors that are difficult to be accurately corrected in Global Navigation Satellite System (GNSS) Precise Point Positioning Ambiguity Resolution (PPP-AR). The tropospheric residuals due to imperfect modeling can be significant in harsh environments, like in regions with complex terrain and during ...

Multi-GNSS double/triple-frequency PPP-AR/RTK performance evaluation in the European region

With the continuous development and updates of GNSS systems, an increasing number of satellites now emit triple-frequency signals. Currently, research on triple-frequency positioning is predominantly focused on the Asian region, with limited attention given to the multi-frequency positioning performance in Europe.
