GPS Multipath Analysis Using Fresnel Zones

Florian Zimmermann, +3 more
- 21 Dec 2018 - 
TL;DR: The comparison of simulated and real signal-to-noise (SNR) observations reveals a relationship between the percentage of the overlap of the Fresnel zone and reflector and the occurrence of multipath.

Undifferenced Cycle Slip Estimation of Triple-Frequency BeiDou Signals with Ionosphere Prediction

Bofeng Li, +3 more
- 30 Jun 2016 - 
TL;DR: In this article, a cycle slip detection method for undifferenced BeiDou satellite navigation system (BDS) triple-frequency observations in kinematic scenario is discussed, where two geometry-free extra-wide-lane combinations and one geometry free narrow-lane (NL) combinations are employed.

Performance Analysis of Joint Multi-Antenna Spoofing Detection and Attitude Estimation

Andriy Konovaltsev, +3 more
TL;DR: In this paper, the authors present the results of field tests of a technique for detection of spoofing signals using the direction-of-arrival (DOA) measurements obtained by processing signals of an adaptive antenna array.

Bayesian nonlinear filters for Direct Position Estimation

Pau Closas, +1 more
TL;DR: The core idea is to merge a motion model based on the observations of an Inertial Measurement Unit with a signal model parameterized by the position of the receiver, to be estimated.

Foundation and performance evaluation of real-time GNSS high-precision one-way timing system

Wenfei Guo, +7 more
- 01 Jan 2019 - 
TL;DR: This work establishes a one-way timing system based on a ground-based augmentation system, including the time reference, the PPP algorithm, and the timing receiver technologies, and presents the precision and stability evaluation of the whole system.
