We report the results of position ties for short baselines at eight geodetic sites based on phase delays that are extracted from global geodetic very‐long‐baseline interferometry (VLBI) observations rather than dedicated ... -
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 ... -
GLONASS FDMA data for RTK positioning: a five-system analysis
The use of the GLONASS legacy signals for real-time kinematic positioning is considered. Due to the FDMA multiplexing scheme, the conventional CDMA observation model has to be modified to restore the integer estimability ... -
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

; 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 ... -
Two methods to determine scale-independent GPS PCOs and GNSS-based terrestrial scale: comparison and cross-check
The GPS satellite transmitter antenna phase center offsets (PCOs) can be estimated in a global adjustment by constraining the ground station coordinates to the current International Terrestrial Reference Frame (ITRF). ...
