More reliable global ionospheric maps combined from ionospheric products of the seven IGS analysis centersIonosphereTotal electron contentGlobal ionospheric mapsCombinationA new method is proposed for the combination of global ionospheric maps provided by the seven IGS centers. Through comparison, the GIMs ...
To pave the way for future provision of high-quality data and products for all constellations, the IGS has initiated the Multi-GNSS Experiment (MGEX) under coordination of its Multi-GNSS Working Group. MGEX serves as a framework for increasing the overall awareness of multi-GNSS within the scie...
for the improvement and extension of the International Terrestrial Reference Frame (ITRF), the monitoring of solid Earth deformations, the monitoring of Earth rotation and variations in the liquid Earth (sea level, ice-sheets, etc.), for scientific satellite orbit determinations, ionosphere monitoring...
GPS/Galileo daily PPP-AR can usually achieve a positioning precision of 2, 2 and 6 mm for the east, north and up components, respectively, for all phase bias products except those based on German Research Centre for Geosciences (GBM) rapid satellite orbits and clocks. Due to the ...
The multi-GNSS RT-PPP undoubtedly can greatly improve the positioning accuracy and shorten the convergence time. However, the RTS is currently offered only for GPS, while multi-GNSS products are still in the stage of developing and testing. Thus, different ACs provide different RTS products, as...
(ground- and satellite-based), DORIS, VLBI, satellite altimetry or the GPS radio occultation missions can provide valuable information on the electron density. The potential for ionospheric sensing using these techniques has improved consid erably over the last few years. The ionosphere session will...
VTEC evolution trend/ A9420Q Ionospheric particle precipitation A9480 Instrumentation and techniques for aeronomy, space physics, and cosmic raysThe International GNSS Service (IGS) Working Group on Ionosphere was created in 1998. Since then, the Scientific community behind IGS, in particular CODE, ...
We show the improvements in stability and accuracy resutling from the use of the IGS products, rather than the standard broadcast Klobuchar model for the ionosphere. when compared to ionospheric corrections from on-site dual-frequency measurements with non-calibrated receivers (the method previously ...
The result showed that the root mean square (RMS) of CNES VTEC products compared with the IGS final GIM is about 1–3 TECU, and the RT-SF-PPP using this ionosphere product can achieve sub-meter-level and meter-level positioning accuracy in horizontal and vertical components, respectively. ...
