An East-West Network of Twelve Global Navigation Satellite System (GNSS) Stations in the Summit Region of Greenland: RINEX Data, 2022-2025

In 2022, twelve experimental, low-cost, low-power Global Navigation Satellite System (GNSS/GLONASS) stations were deployed in vicinity of Summit Station, Greenland to measure ice velocity, validate Ice, Cloud, and land Elevation Satellite 2 (ICESat-2) altimetry, and study surface processes. Eleven stations logged data once or twice monthly for 24 hours to correspond to the overflight of the ICESat-2 satellite, while the twelfth station logged data once weekly for a 24 hour period. In 2023, an additional station was installed and logged data daily for 3 hours. Nine stations were decommissioned in June 2024, while the remaining four were serviced and raised. Here, we provide minimally-processed RINEX files for each of these GNSS stations. The GNSS instruments are built on the u-blox ZED family of receivers, and therefore we convert the raw .ubx data into RINEX for ease of use here. More information on the open source instrument can be found here: https://github.com/glaciology/OGRE. (On Ice GNSS Research Equipment). The file naming convention is as follows: XXXXDDD0.YYo, where XXXX is the four letter station identifier (see OGRENet_Map_2.png for map of four letter stations), DDD is the nth day of year, and YY is the two digit year identifier. Stations with multiple names (XXXX) indicate the instrument was repositioned horizontally during the summer of 2024.
