MSTID Detection, Characterization and Modelling: A Key Point to Improve the Precise GNSS Navigation
2008
The main focus of this paper is to show how the better knowledge of the behaviour of the more common ionospheric perturbations (the so called Medium Scale Travelling Ionospheric Disturbances, MSTIDs) can significantly improve the precise GNSS real-time positioning. In order to do this, three main studies has been carried out: 1) To develop a simple but accurate MSTID detection and characterization algorithm. 2) To apply this technique to extract the MSTID worldwide behaviour, in terms of occurrence, velocity, azimuth and period. 3) To form a simple blind MSTID model, summarizing these results (the main point detailed in this manuscript). This model is applied to real-time positioning scenarios, to show the significant reduction of positioning error. This increase of performance is achieved in both “classical ” short baselines of few tens of kilometres (those covered by RTK and VRS techniques), as well as in very long baselines of hundreds of kilometres (by using the Wide Area RTK te...

Validation results on the latest version of TaD model (TaDv2) show realistic reconstruction of the electron density profiles (EDPs) with an average error of 3 TECU, similar to the error obtained from GNSS-TEC calculated paremeters. The work presented here has the aim to further improve the accuracy of the TaD topside reconstruction, adjusting the TEC parameter calculated from TaD model with the TEC parameter calculated by GNSS transmitting RINEX files provided by receivers co-located with the Digisondes. The performance of the new version is tested during a storm period demonstrating further improvements in respect to the previous version. Statistical comparison of modeled and observed TEC confirms the validity of the proposed adjustment. A significant benefit of the proposed upgrade is that it facilitates the real-time implementation of TaD. The model needs a reliable measure of the scale height at the peak height, which is supposed to be provided by Digisondes. Oftenly, the automatic scaling software fails to correctly calculate the scale height at the peak, H m , due to interferences in the receiving signal. Consequently the model estimated topside scale height is wrongly calculated leading to unrealistic results for the modeled EDP. The proposed TEC adjustment forces the model to correctly reproduce the topside scale height, despite the inaccurate values of H m . This adjustment is very important for the application of TaD in an operational environment.

Advanced GNSS Tropospheric Products for Monitoring Severe Weather Events and Climate, 2019
Over the last decade, near real-time analysis of GPS data has become a well-established atmospheric observing tool, primarily coordinated by the EIG EUMETNET GPS Water Vapour Programme (E-GVAP) in Europe. In the near future, four operational GNSS will be available for commercial and scientific applications with atmospheric science benefiting from new signals from up to 60 satellites observed at any one place and time, however, many challenges remain regarding their optimal combined utilization. Besides raw data streaming, recent availability of precise real-time orbit and clock corrections enable wide utilization of autonomous Precise Point Positioning (PPP), which is particularly efficient for highrate, real-time and multi-GNSS analyses. New GNSS constellation signals, products and processing methods suggest the development of advanced GNSS tropospheric products, in support of weather

The ACES GNSS subsystem and its applications
The ESA mission Atomic Clock Ensemble in Space (ACES) will operate a new generation of atomic clocks on board the International Space Station (ISS) in 2013-2015 timeframe. The ACES payload will be attached externally to the European Columbus module. The ACES clock signal will reach fractional frequency stability and accuracy of 1 part in 10-16. A GNSS receiver will be connected to the ACES clock signal. Primarily, the GNSS receiver will ensure orbit determination of the ACES clocks using GPS, GALILEO/GIOVE, and possibly GLONASS satellite signals in the L1, L2, and L5/E5a bands. Orbit determination is important for the correct evaluation of relativistic corrections in the space-to-ground comparison of clocks. Secondarily, the receiver offers the potential to support additional functionality for remote sensing applications in the field of GNSS radio-occultation and GNSS reflectometry, exploiting opportunities arising from the new GPS and GALILEO/GIOVE signals. The ACES GNSS instrument...
