Inventory of natural processes with nautical charts, real-time kinematic global navigation satellite systems (RTK-GNSS), and unmanned aerial vehicle (UAV), Trindade Island, Brazil

Brazilian Journal of Geology, 2022
Abstract The volcanic Trindade Island is a remote Brazilian offshore territory in the South Atlantic, located ca. 1.140 kilometers east of the southeast coast of Brazil. The island’s permanent exposure to geological hazards requires assessment. However, the lack of erosion and landslides temporal data impedes predictive geohazard analyses.

Internal Structure, Kinematics, and Prehistory of Frozen Debris Lobe‐A (FDL‐A), Brooks Range, Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Frozen Debris Lobe‐A (FDL‐A)—one of hundreds of FDLs in the Brooks Range of northern Alaska—is a slow‐moving landslide in permafrost that has been the subject of research since 2008 due to its close proximity to the Dalton Highway. Here, we synthesize more than a decade's worth of climate and surface measurements of monitored FDLs, and the ...

Research of real-time kinematic satellite positioning technology (RTK) for monitoring landslide deformations

Sustainable Development of Mountain Territories
Introduction. The article deals with the issues of geodetic control of displacements of the observation station’s working benchmarks on landslide slopes. The authors assume that by using Real-Time Kinematic (RTK) satellite positioning technology to determine the displacements of the observation station’s working benchmarks fixed in the landslide body ...

A reference station-based GNSS computing mode to support unified precise point positioning and real-time kinematic services [PDF]

, 2013
Currently, the GNSS computing modes are of two classes: network-based data processing and user receiver-based processing. A GNSS reference receiver station essentially contributes raw measurement data in either the RINEX file format or as real-time data ...
