Unconstrained GNSS Water Vapor Tomography With Real Data and LEO Augmentation

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The availability of four complete GNSS constellations (GPS, GLONASS, BeiDou and Galileo) offers, for the first time, the possibility of performing water vapor tomographic inversions that do not rely on external data. A tomographic model that includes no external constraints and requires no first guess and no virtual observations is described ...

Modelling of GPS tropospheric delay wet Neill mapping function (NMF) [PDF]

, 2014
The modeling of the GPS tropospheric delay mapping function should be revised by modifying or simplify its mathematical model. Some current mapping functions models are separated into hydrostatic and the wet part.

Generation of Meteorological Parameters for Tropospheric Delay on GNSS Signal

, 2008
The GNSS (Global Navigation Satellite System) signal is delayed by the neutral atmosphere at the troposphere, so that the delay is one of major error sources for GNSS precise positioning. The tropospheric delay is an integrated refractive index along the

Impact of different tropospheric delay models on GNSS positioning quality

, 2017
Vpliv troposferske refrakcije na opazovanja GNSS je eden izmed glavnih vplivov, ki znižujejo kakovost položaja, določenega z GNSS. Čim kakovostnejše modeliranje troposferske refrakcije je zato ključno za določitev položaja z visoko točnostjo in ...

Improving GNSS precise point positioning with tropospheric constraints from data-driven numerical weather prediction model

Geo-spatial Information Science
Accurate priori tropospheric knowledge is advantageous for Global Navigation Satellite System (GNSS) precise point positioning (PPP), which significantly influences both convergence time and the accuracy of tropospheric delay estimations.
