Abstract: Ionospheric scintillation can degrade the global navigation satellite system (GNSS) measurement quality and even result in loss of signal lock, thus degrading the accuracy and reliability of GNSS precise point positioning (PPP). To reduce the… read more here.

DOI: 10.1109/taes.2024.3360380
Abstract: The global navigation satellite system (GNSS) PPP-RTK technique, which integrates the superiorities of precise point positioning (PPP) and real-time kinematic (RTK), is increasingly attracting people's attention in recent years. This article proposes a factor graph… read more here.
