Initial assessment of precise point positioning with LEO enhanced Global Navigation Satellite Systems (LeGNSS)
TL;DR: Simulation results show that LeGNSS can decrease the PPP convergence to 5 min, and it is expected that the initialization of PPP can be further shortened.

Performance of Galileo-only dual-frequency absolute positioning using the fully serviceable Galileo constellation
TL;DR: The daily static positioning based on the broadcast ephemeris using Galileo pseudoranges is significantly more accurate than the corresponding GPS solutions, obtaining the accuracy of a few decimeters.

Assessing the latest performance of Galileo-only PPP and the contribution of Galileo to Multi-GNSS PPP
TL;DR: Assessment of the latest performance of the Galileo-only precise point positioning (PPP) and the contribution of Galileo to the Multi-GNSS PPP solutions shows that the three-dimensional positioning accuracy of Galileo static and kinematic PPP can reach centimeter level and decimeter level after convergence, respectively.

Triple-frequency multi-GNSS reflectometry snow depth retrieval by using clustering and normalization algorithm to compensate terrain variation
TL;DR: In this paper, a combination of GNSS triple-frequency carrier phase and the topographic feature of the reflecting surface is considered for estimating the snow depth by using the density-based spatial clustering of applications with noise algorithm and normalization method.

Bridge monitoring using multi-GNSS observations with high cutoff elevations: A case study
TL;DR: A multi-GNSS integration processing method is proposed and a case study on bridge monitoring using multi- GNSS observations with high cutoff elevations is presented, showing that, with more satellites available and the strongest satellite geometry, the combined GPS/BDS/GLONASS shows the highest precision.
