UnICorn: Unlocking the InSAR 3D velocity field with extra GNSS measurements north of the Corinth Rift

The UnICorn project established a continuous Global Navigation Satellite System (GNSS) network in the Thessaly and Epirus regions of northern Greece to improve the integration of GNSS with Interferometric Synthetic Aperture Radar (InSAR) observations. Six continuous GNSS stations were installed on publicly owned buildings using low-cost instrumentation consisting of u-blox ANN-MB2-00 multi-band patch antennas and maRam UG tinyBlack receivers equipped with Swift Navigation Piksi Multi GNSS modules. One station (P033) was later removed following a hardware failure; the remaining five stations continue to operate. Observations are recorded continuously at a 30-second sampling interval and converted from the native binary format to standard RINEX files. The dataset includes observations from the GPS and GLONASS constellations. Detailed station metadata are provided in the accompanying site log files. The data are hosted on a dedicated FTP server (ftp://ogl.geo.ruhr-uni-bochum.de). Access is available upon request. To obtain access, please complete the data request form and submit it to the email address given on the form. After approval, users will receive the FTP connection details and access credentials.
