Journal ArticleDOI
Review of the state of the art and future prospects of the ground-based GNSS meteorology in Europe
Guergana Guerova,Jonathan Jones,Jan Dousa,Galina Dick,Siebren de Haan,Eric Pottiaux,Olivier Bock,Rosa Pacione,Gunnar Elgered,Henrik Vedel,Michael Bender +10 more
TL;DR: In this paper, a review of the state of the art in Global Navigation Satellite System (GNSS) meteorology in Europe is presented, which covers the advances in GNSS processing for derivation of tropospheric products.
Journal ArticleDOI
A computationally efficient approach for estimating high-rate satellite clock corrections in realtime
TL;DR: Estimation of high-rate satellite clocks from a large reference network and tracking satellites of multi-GNSS constellations becomes achievable because the computation time is reduced to one-tenth.
Journal ArticleDOI
Real-time zenith tropospheric delays in support of numerical weather prediction applications
Jan Dousa,Pavel Václavovic +1 more
TL;DR: In this paper, a real-time solution for numerical weather prediction (NWP) nowcasting and severe weather event monitoring based on real time global orbits and clocks from the International GNSS Service (IGS) and Precise Point Positioning (PPP) processing strategy is presented.
Journal ArticleDOI
Real-time precise point positioning regional augmentation for large GPS reference networks
TL;DR: A multi-layer processing scheme for precise point positioning (PPP) regional augmentation to avoid processing large networks and results indicate that a reliable fixing is possible after 5 s on average, and the augmentation corrections from the regional network are investigated.
Journal ArticleDOI
An improved model for calculating tropospheric wet delay
Jan Dousa,Michal Elias +1 more
TL;DR: In this article, a new concept is described for calculating the tropospheric zenith wet delay and its vertical approximation derived from the original profile of meteorological data, and a new parameter of ZWD exponential decay is introduced which, together with a reference value, represents ZWD corrections accurately up to 10 km altitude.
