Precise Point Positioning Using Triple GNSS Constellations in Various Modes
This paper introduces a new dual-frequency precise point positioning (PPP) model, which combines the observations from three different global navigation satellite system (GNSS) constellations, namely GPS, Galileo, and BeiDou. Combining measurements from different GNSS systems introduces additional biases, including inter-system bias and hardware delays, which require rigorous modelling. Our mod...
متن کاملStudy and analysis of Differential GNSS and Precise Point Positioning
The Global Positioning system (GPS) is used for navigation and associated tasks in wide variety of applications. One of the primary modes of GPS operation is differential GPS. Differential GPS allows more accurate positioning than stand-alone GPS. Many new applications are possible because of the increased accuracy obtained through differential GPS. In this paper the techniques and methods of d...
متن کاملWeighting of Multi-GNSS Observations in Real-Time Precise Point Positioning
The combination of Global Navigation Satellite Systems (GNSS) may improve the accuracy and precision of estimated coordinates, as well as the convergence time of Precise Point Positioning (PPP) solutions. The key conditions are the correct functional model and the proper weighting of observations, for which different characteristics of multi-GNSS signals should be taken into account. In post-pr...
متن کاملKinematic Precise Point Positioning Using Multi-Constellation Global Navigation Satellite System (GNSS) Observations
Multi-constellation global navigation satellite systems (GNSSs) are expected to enhance the capability of precise point positioning (PPP) by improving the positioning accuracy and reducing the convergence time because more satellites will be available. This paper discusses the performance of multi-constellation kinematic PPP based on a multi-constellation kinematic PPP model, Kalman filter and ...
متن کاملPrecise Point Positioning: Is the Era of Differential GNSS Positioning Drawing to an End?
SUMMARY For three decades the differential GPS (DGPS), and subsequently DGNSS, technique has been the dominant operational mode for precise positioning for the geoscience, geospatial and navigation communities. All DGNSS techniques perform positioning relative to one or more reference GNSS receivers located at points of known coordinates. Depending upon the type of GNSS measurement, user equipm...
