Estimation of phase and code biases on multiple frequencies with a Kalman filter
TL;DR: In this paper, a method for bias estimation on multiple frequencies with a Kalman filter is proposed, which consists of four steps: first, a least-squares estimation of ranges, ionospheric delays, ambiguities, receiver phase biases and satellite phase biases is performed.

GNSS signal-based snow water equivalent determination for different snowpack conditions along a steep elevation gradient
Achille Capelli,Franziska Koch,Patrick Henkel,Markus Lamm,Florian Appel,Christoph Marty,Jürg Schweizer +6 more
TL;DR: In this article, the authors evaluated the applicability of the GNSS-based SWE measurement at four stations along a steep elevation gradient (820, 1185, 1510 and 2540m) in the eastern Swiss Alps during two winter seasons (2018-2020).

Real-time kinematic positioning for unmanned air vehicles
Patrick Henkel,Andreas Sperl +1 more
TL;DR: An RTK method which estimates a code multipath parameter for each double difference to fully exploit the temporal correlation of multipath and to prevent a mapping of the multipath into the baseline and ambiguities was applied to real measurements and enabled a millimeterlevel positioning accuracy.

Method, network of reference stations and mobile navigation device for determining at least one real valued parameter of a receiver, in particular an absolute or relative position of the receiver, by means of a satellite navigation system
Andreas Brack,Patrick Henkel +1 more
TL;DR: In this paper, a method for determining at least one real-valued parameter, in particular an absolute or relative position of a receiver, was proposed, which uses a satellite navigation system comprising a plurality of satellites, which emit navigation signals on carrier signals.
Journal ArticleDOI
Estimation of satellite position, clock and phase bias corrections
TL;DR: The method processes uncombined and undifferenced measurements of an arbitrary number of frequencies such that the obtained satellite position, clock and bias corrections can be used for any type of differenced and/or combined measurements.
