recommendations! Published in 2024 at "Journal of Geodesy"

DOI: 10.1007/s00190-024-01829-2

Abstract: Radio signals transmitted by Global Navigation Satellite System (GNSS) satellites experience tropospheric delays. While the hydrostatic part, referred to as zenith hydrostatic delay (ZHD) when mapped to the zenith direction, can be analytically modelled with… read more here.

DOI: 10.1007/s10291-023-01608-0

Abstract: The precise point positioning real-time kinematic (PPP-RTK) is a high-precision global navigation satellite system (GNSS) positioning technique that combines the advantages of wide-area coverage in precise point positioning (PPP) and of rapid convergence in real-time… read more here.

DOI: 10.1109/access.2020.3003580

Abstract: With the development of industrialization, fine particulate matter (PM2.5) severely chills the health of people. Studies have shown that the variation of PM2.5 concentration is related to the Global Navigation Satellite System (GNSS) tropospheric delay.… read more here.

DOI: 10.5194/angeo-36-1507-2018

Abstract: Abstract. Tropospheric delay is an important error source in space geodetic techniques. The temporal and spatial variations of the zenith wet delay (ZWD) are very large and thus limit the accuracy of tropospheric delay modelling.… read more here.
