Flex power on GPS Block IIR-M and IIF
TL;DR: In this paper, the impact of flex power on the tracking and measurements of geodetic receivers is investigated with a 30m high-gain antenna, showing an increase of P(Y)-code power by 5 and 6 dB for L1 and L2, respectively, due to deactivation of the military M-code on both frequencies.

A New Online Service for the Validation of Multi-GNSS Orbits Using SLR
TL;DR: The goal of the paper and GOVUS itself is to determine what is the current quality of multi-GNSS orbits validated using SLR results; what kinds of systematic errors can affect GNSS orbits and SLR observations; and how to provide the online analysis tools to the broadest possible multi- GNSS community.

Railway irregularity measuring using Rauch–Tung–Striebel smoothed multi-sensors fusion system: quad-GNSS PPP, IMU, odometer, and track gauge
TL;DR: A multi-sensors fusion system consisting of multi-constellation global navigation satellite systems (GNSS)-based precise point positioning, inertial navigation system, odometer, and track gauge is proposed and is further enhanced by using the Rauch–Tung–Striebel smoother.
Journal ArticleDOI
An efficient solution of real-time data processing for multi-GNSS network
TL;DR: The blocked QR factorization of the simulated matrix can greatly improve processing efficiency with a magnitude of nearly two orders on a personal computer with four 3.30 GHz cores.
Journal ArticleDOI
Five-frequency Galileo long-baseline ambiguity resolution with multipath mitigation
TL;DR: In this article, the authors make use of real Galileo observations on five frequencies with a sampling interval of 1 s to study the formal and empirical ambiguity success rates in case of full ambiguity resolution (FAR), where the multipath effects are mitigated using the measurements of another day when the constellation repeats.
