Precise point positioning with multipath estimation [PDF]

open access: yes2016 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2016
Precise Point Positioning with low-cost GNSS receivers is attractive for numerous applications, as it can provide centimeter-level positioning without the exchange of raw measurements from a reference station. However, pseudorange multipath has to be accurately considered for a reliable ambiguity fixing. In this paper, we derive a precise model for the

The application of Precise Point Positioning in Geosciences [PDF]

open access: yesThe 9th International Conference "Environmental Engineering 2014", 2014
Precise Point Positioning (PPP), an absolute positioning method, is an alternative for conventional relative positioning. Currently the PPP accuracy, is on the level of few-centimetres for static and decimetre for kinematic positioning respectively. However, long convergence time of PPP results is observed.

Precise Point Positioning Technique Versus Relative Positioning [PDF]

open access: yesBaltic Surveying, 2020
Precise point positioning is a GNSS based positioning method that is known to regaining more precise information about major systematical errors in its functional model. This method is seen as an advanced version of the conventional absolute positioning method that is able to offer higher accuracy of the estimate parameter.

PositNN: Training Deep Neural Networks with Mixed Low-Precision Posit [PDF]

open access: yesICASSP 2021 - 2021 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), pp. 7908-7912, 2021
Low-precision formats have proven to be an efficient way to reduce not only the memory footprint but also the hardware resources and power consumption of deep learning computations. Under this premise, the posit numerical format appears to be a highly viable substitute for the IEEE floating-point, but its application to neural networks training still ...

Vulnerabilities and integrity of precise point positioning for intelligent transport systems: overview and analysis

open access: yesSatellite Navigation, 2021
The implementation of Intelligent Transport System (ITS) technology is expected to significantly improve road safety and traffic efficiency. One of the key components of ITS is precise vehicle positioning. Positioning with decimetre to sub-metre accuracy

A Method to Mitigate the Effects of Strong Geomagnetic Storm on GNSS Precise Point Positioning

open access: yesSpace Weather, 2022
Geomagnetic storm can affect the performance of Global Navigation Satellite System (GNSS) precise positioning services. To mitigate the adverse effects of strong geomagnetic storms, we propose to establish the geometry‐free (GF) cycle slip threshold ...

Precise Point Positioning with Kepler [PDF]

open access: yes2019 IEEE 90th Vehicular Technology Conference (VTC2019-Fall), 2019
Precise Point Positioning (PPP) enables an absolute positioning with centimeter-level accuracy without the need of raw measurements from a reference station. However, today's GPS L1/ L2-based PPP solutions typically need more than 30 minutes to converge.
