Our customer was looking for a low cost solution for glacier dynamic measurements with decimeter accuracy and low or no probability of recovering the GPS system – the GPS setup was likely to fall in the sea as the glacier would melt. The Hemisphere Crescent OEM board single channel (725-1247-00) was recommended along with Hemisphere A20 antenna (804-3032-000). We believe that the customer data was collected at 1 Hz on a CF card and/or transmitted on a short distance to a data logger for storage. Data was extracted with RINEX Hemisphere utility and post processed where DGPS corrections were applied.
