recommendations! Published in 2018 at "GPS Solutions"

DOI: 10.1007/s10291-018-0799-6

Abstract: Since carrier phase multipath cannot be easily captured or mitigated, especially in real-time and kinematic applications, it is necessary to assess the multipath significance. We propose a real-time multipath detection method using dual-frequency carrier-to-noise-power-density ratio… read more here.

recommendations! Published in 2020 at "GPS Solutions"

DOI: 10.1007/s10291-020-01006-w

Abstract: Urban environments present significant challenges to global navigation satellite system (GNSS) positioning. GNSS signals are often obstructed by buildings and other obstacles, leading to reflection and diffraction, which cause major line-of-sight (LOS) and non-line-of-sight (NLOS)… read more here.
