Journal ArticleDOI
Multifrequency, Multisatellite Vector Phase-Locked Loop for Robust Carrier Tracking
TL;DR: A new vector phase-locked loop for joint tracking of carrier phase from all satellites on multiple frequencies is presented, which increases the robustness to ionospheric scintillations, carrier phase multipath and interference from jammer.
Journal ArticleDOI
Reliable Integer Ambiguity Resolution: Multi‐Frequency Code Carrier Linear Combinations and Statistical A Priori Knowledge of Attitude
Patrick Henkel,Christoph Günther +1 more
TL;DR: In this paper, a group of multi-frequency linear combinations that include both code and carrier phase measurements were proposed to improve the reliability of integer ambiguity resolution. But the accuracy of the float solution was not improved.
Journal ArticleDOI
Snow Water Equivalent of Dry Snow Derived From GNSS Carrier Phases
Patrick Henkel,Franziska Koch,Florian Appel,Heike Bach,Monika Prasch,Lino Schmid,Jürg Schweizer,Wolfram Mauser +7 more
TL;DR: The SWE derived solely by the GNSS shows very high correlation with conventionally measured snow pillow and manual snow pit data and can be applied to dense low-cost GNSS receiver networks to improve the spatial and temporal information on snow.
Journal ArticleDOI
Retrieval of Snow Water Equivalent, Liquid Water Content, and Snow Height of Dry and Wet Snow by Combining GPS Signal Attenuation and Time Delay
Franziska Koch,Franziska Koch,Patrick Henkel,Florian Appel,Lino Schmid,Heike Bach,Markus Lamm,Monika Prasch,Jürg Schweizer,Wolfram Mauser +9 more
TL;DR: In this paper, a non-destructive approach based on Global Positioning System (GPS) signals was developed to derive SWE, snow height (HS), and snow liquid water content (LWC) simultaneously using one sensor setup only.
Journal ArticleDOI
Partial integer decorrelation: optimum trade-off between variance reduction and bias amplification
Patrick Henkel,Christoph Günther +1 more
TL;DR: In this article, a linear combination of E1 and E5 code and carrier phase measurements with a wavelength of 3.285 m and a noise level of a few centimeters is derived.
