The RINEX Dataset to the IGS Receiver Antenna Ring Calibration Campaign 2022-2024 (IGS RingCalVal)

Dataset Information The Institut für Erdmessung at Leibniz University Hannover participated in the IGS ring receiver antenna calibration and validation campaign. During this campaign, raw data were collected on the laboratory roof of the institute. An external Rubidium clock, specifically a Stanford FS725 Benchmark known for its precision with an aging rate of 2×10^(−11), was used. The data also included information for a short baseline relative to the MSD8, using a similar type of receiver. For the antenna calibration, a JAVAD Delta TRE_S3S model was employed alongside a common clock ensemble to ensure accuracy. The offset from the mounting point to the antenna reference point (ARP) was carefully measured with a slide caliper and found to be precise as 0.2 mm. Additionally, reference coordinates for the setup were available to aid in the validation process.

Please check data, e.g. signal strength over days, by analysing data to ensure that there are no problems with the measurement data!
