Example of time-series data from one of our GNSS pairs monitoring coastal landslides at Whitby, NE England

Since the autumn we’ve been running a successful field test to demonstrate the utility of our low-cost GNSS units to monitor ground movement cause by local landslides on the coast near Whitby (NE England). This was part of the “Mostly Coastal” project funded by ESA Business Applications (European Space Agency) and the UK Satellite Applications Catapult to look at wider uses of satellite data.

The snapshot above is an example of our digital dashboard. The lower time-series shows data from one pair of GNSS units (from a total of eight stations), with two clear slip events each around 1.5 cm in magnitude, and a third slip of less than a cm. Each of these events correlates temporally with precipitation rate (upper graph).

High spatial and temporal precision and resolution from low-cost hardware!
