Real-time GNSS precise point positioning using improved robust adaptive Kalman filter
TL;DR: A real-time GPS/Galileo PPP system, which employs a modified version of CAKF called the Improved Robust adaptive Kalman Filter (IRKF), which indicates that when the IRKF approach is utilised, the positioning accuracy is significantly improved and the convergence behaviour is enhanced compared with results from EKF, conventional RKF

GNSS-R Snow Depth Inversion Based on Variational Mode Decomposition With Multi-GNSS Constellations
TL;DR: In this article , a variational mode decomposition (VMD) algorithm with the characteristics of an adaptive high-pass filter was proposed to detrend the SNR data. And the experimental results of KIRU station and P351 station showed that VMD algorithm is suitable for different constellations and has better signal separation effect.

Assessment of L5 frequency on real-time GPS orbit and clock estimation
TL;DR: The triple-frequency model for real-time GPS satellite orbit and clock estimation is derived and the influence of L5 frequency observations on real- time GPS satellite orbits and clock are analyzed.
Journal ArticleDOI
Impact of sample correlation on SISRE overbound for ARAIM
TL;DR: Results show that the time between effective independent samples is highly dependent on the constellation and onboard clock type, and the so-called uncertainty factor by which the Gaussian distribution needs to be inflated in order to account for the observation data independence.

Broadcast Ephemeris with Centimetric Accuracy: Test Results for GPS, Galileo, Beidou and Glonass
Alessandro Caporali,J. Zurutuza +1 more
TL;DR: In this article, the capability of the broadcast ephemeris message in both GPS-like (Keplerian ellipse with secular and periodic perturbations) and Glonass-like formats, to reproduce a corresponding precise ECEF was evaluated.
