- Statement
- Data were collected with two Leica VIVA GS10 GNSS receivers: one as a stationary base station and one roving station carried by the operator walking around the snow patch. Data recorded in the field were processed in Post-Processed Kinematic mode, which means that the accurate positions of the points on the perimeter were not calculated in real time, but raw Global Navigation Satellite System logs were processed afterwards. Standard deviations give calculated accuracy of post-processed points. Sudden increases in standard deviation to ~0.01 m horizontal and ~0.04 m vertical show points that were recorded during failures of the base station power. Differential accuracy was achieved for these points by tying them to the British Isles continuous GNSS Facility (BIGF) station at Braemar, 19 km away, instead.
