Characterization of Crustal Deformation During the May 2021 Nyiragongo Eruption Using InSAR and GNSS Data

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract We analyze Interferometric Synthetic Aperture Radar (InSAR) and Global Navigation Satellite System (GNSS) data to characterize ground deformation and dike opening associated with the May 2021 Nyiragongo eruption. Despite documented eruptions in 1977 and 2002, Nyiragongo's magmatic system and its interaction with regional rifting remain poorly ...

Robust Positioning in the Presence of Multipath and NLOS GNSS Signals [PDF]

GNSS signals can be blocked and reflected by nearby objects, such as buildings, walls, and vehicles. They can also be reflected by the ground and by water.
