An Improved Clock Jump Detection Method in Real - Time PPP
2020In view of the fact that most current cycle clip detection methods do not take into account the clock jump of receivers, which results in the reduction of PPP data processing accuracy and efficiency, this paper introduce the GNSS receiver clock jump theory systematically, to analyze its impact on the observed data and the cycle clip detection principle

Precise Real-Time Multi-GNSS PPP
2015Global Navigation Satellite System (GNSS) technology has undergone enormous developments over the last three decades. The majority of PNT (Positioning, Navigation and Timing) applications are now based on GNSS. This increasing dependence on GNSS technology is acknowledged by several nations, some of which are even developing their own regional or ...

Airborne Pseudolite Distributed Positioning based on Real-time GNSS PPP
Journal of Navigation, 2019Airborne-Pseudolite (A-PL) systems have been proposed to augment Global Navigation Satellite Systems (GNSSs) in difficult areas where GNSS-only navigation cannot be guaranteed due to signal blockages, signal jamming, etc. One of the challenges in realising such a system is to determine the coordinates of the A-PLs to a high accuracy.

Performance assessment of multi-GNSS real-time PPP over Iran
Advances in Space Research, 2017Abstract With the advent of multi-GNSS constellations and thanks to providing the real-time precise products by IGS, multi-GNSS Real-Time PPP has been of special interest to the geodetic community. These products stream in the form of RTCM-SSR through NTRIP broadcaster.

PPP augmentation and real-time precise orbit determination for LEO satellites
2017 36th Chinese Control Conference (CCC), 2017It is valuable for ground users to realize centimeter-level positioning based on PPP. However, the initialization of PPP algorithm costs a long time, which limits its application. In order to achieve the near-real-time PPP positioning for users, an augmentation scheme by utilizing LEO satellite is proposed so as to improve the initialization speed of ...
