Calibrating receiver-type-dependent wide-lane uncalibrated phase delay biases for PPP integer ambiguity resolution
Wide-lane (WL) uncalibrated phase delay (UPD) is usually derived from Melbourne–Wübbena (MW) linear combination and is a prerequisite in Global Navigation Satellite Systems (GNSS) precise point positioning (PPP) ambiguity ... -
GPS + Galileo + BeiDou precise point positioning with triple-frequency ambiguity resolution
Along with the rapid development of GNSS, not only BeiDou, but also Galileo, and the newly launched GPS satellites can provide signals on three frequencies at present. To fully take advantage of the multi-frequency ... -
Impact of Tropospheric Ties on UT1‐UTC in GNSS and VLBI Integrated Solution of Intensive Sessions
Wang, Jungang; Ge, Maorong; Glaser, Susanne; Balidakis, Kyriakos; Heinkelmann, Robert; Schuh, Harald (Journal of Geophysical Research: Solid Earth, 2022-11-11)Very Long Baseline Interferometry (VLBI) intensive (INT) sessions are critical for the rapid determination and densification of Universal Time 1‐Coordinate Universal Time (UT1‐UTC), which plays an important role in satellite ... -
Improving the Vertical Modeling of Tropospheric Delay
Wang, Jungang; Balidakis, Kyriakos; Zus, Florian; Chang, Xiao; Ge, Maorong; Heinkelmann, Robert; Schuh, Harald (Geophysical Research Letters, 2022-03-08)Accurate tropospheric delays from Numerical Weather Models (NWM) are an important input to space geodetic techniques, especially for precise real‐time Global Navigation Satellite Systems, which are indispensable to earthquake ... -
Integrated processing of ground- and space-based GPS observations: improving GPS satellite orbits observed with sparse ground networks
Huang, Wen; Männel, Benjamin; Sakic, Pierre; Ge, Maorong; Schuh, Harald (Journal of Geodesy, 2020-10-10)The precise orbit determination (POD) of Global Navigation Satellite System (GNSS) satellites and low Earth orbiters (LEOs) are usually performed independently. It is a potential way to improve the GNSS orbits by integrating ...
