Abstract
Abstract. We have developed a new high-precision GNSS receiver specifically designed for long-term unattended deployments in remote areas. The receiver reports its status, and can be reprogrammed remotely, through an integrated satellite data link. It uses less power than commercially available alternatives while being equally, if not more, accurate. Data are saved locally on dual SD card slots for increased reliability. Deployments of a number of those receivers in several different locations on the Antarctic ice sheet have shown them to be robust and able to operate flawlessly at low temperatures down to −40 °C.
Highlights
Long-term monitoring using permanently installed GNSS receivers is a powerful tool for geophysics research, and this technique is commonly used in various different settings
We describe the design and performance of a new GNSS unit that fits all those criteria
We believe our new GNSS receiver to be of general use for the wider geophysical sciences community, we will focus on its application to remote polar areas
Summary
Long-term monitoring using permanently installed GNSS receivers is a powerful tool for geophysics research, and this technique is commonly used in various different settings. Applications are too numerous to list but include measurements of glacier flow, tectonic movements, ground subsidence and isostatic uplift, to name a few In such applications the reliability of the system is of utmost concern as the GNSS units are often left unattended for prolonged periods of times. We believe our new GNSS receiver to be of general use for the wider geophysical sciences community, we will focus on its application to remote polar areas. This is because our own primary application of GNSS receivers is to monitor the temporal variation in glacier flow in Antarctica. We do not include the antenna or field installation hardware
