Study of high-precision time transfer method enhanced by PPP-AR/PPP-RTK

Measurement Science and Technology
Abstract With the ongoing advancements in the Global Navigation Satellite System (GNSS), the technology for high-precision time transfer facilitated by GNSS has also become increasingly refined. This paper aims to investigate the contribution of information-enhanced GNSS PPP to time transfer performance, with a focus on the comprehensive

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.
