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

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 ...

Real-Time landslide monitoring using single-frequency PPP: Proof of concept
2012 6th ESA Workshop on Satellite Navigation Technologies (Navitec 2012) & European Workshop on GNSS Signals and Signal Processing, 2012Strong need for a sophisticated landslide monitoring and alerting system has grown especially in mountainous regions. Traditionally, monitoring is performed using time-domain reflectometry by geodesists. Since a few years the Global Positioning System (GPS) dual-frequency Real-Time Kinematic (RTK) approach is widely used for monitoring landslides ...

Real-Time Precise Point Positioning (RT-PPP) for Positioning and Mapping
2018Real-Time Precise Point Positioning (RT-PPP) has started to develop among Global Positioning System (GPS) community due to some reasons, such as reference stations are required, very economical and easy to operate from everywhere. By using a dual-frequency receiver with the support from GPS precise products, RT-PPP has proven to give centimetre to ...

AbstractThe multibeam echosounding technique is used to provide seafloor mapping at a relatively high-quality level and requires an accurate positioning and orientation system. Integration of a global positioning system (GPS) and an inertial navigation system (INS) is widely used for positioning and orientation control and is performed by using an ...
