Experience with the GNSS-based tide gauge at the Onsala Space Observatory

Several experiments have been carried out with the GNSS-based tide gauge at the Onsala Space Observatory (OSO) since the end of 2008. GNSS signal reflections from both seawater and sea-ice have been recorded. During one of the campains it was shown that the root-mean-square agreement between the GNS...

Description
Summary:Several experiments have been carried out with the GNSS-based tide gauge at the Onsala Space Observatory (OSO) since the end of 2008. GNSS signal reflections from both seawater and sea-ice have been recorded. During one of the campains it was shown that the root-mean-square agreement between the GNSS-based tide gauge and two stilling well gauges (about 18 km and 33 km away from OSO) were better than 4 cm. Here we present our experiences with the GNSS-based tide gauge from our campains together with new results.
