Calibrating receiver-type-dependent wide-lane uncalibrated phase delay biases for PPP integer ambiguity resolution
(Journal of Geodesy, 2021-06-29)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 ... -
GNSS mobile road dam surveying for TanDEM-X correction to improve the database for floodwater modeling in northern Namibia
(Environmental Earth Sciences, 2020-06-28)The aim of this study is the improvement of the TanDEM-X elevation model for future floodwater modeling by implementing surveyed road dams and the use of filter algorithms. Modern satellite systems like TanDEM-X deliver ... -
GPS + Galileo + BeiDou precise point positioning with triple-frequency ambiguity resolution
(GPS Solutions, 2020-05-27)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 ... -
Precise point positioning with GPS and Galileo broadcast ephemerides
(GPS Solutions, 2021-03-27)For more than 20 years, precise point positioning (PPP) has been a well-established technique for carrier phase-based navigation. Traditionally, it relies on precise orbit and clock products to achieve accuracies in the ...
