説明
Multipath from flat reflecting surfaces causes cyclic changes in quantities such as signal-to-noise ratio (SNR) or L4 (difference between the two L-band phases) of microwave signals from Global Positioning System (GPS) satellites. By analyzing their temporal changes, we can infer heights of GPS antennas from such surfaces, e.g. ground or sea surface. In this study we explore the possibility of measuring the sea surface height (SSH) with GPS stations deployed for crustal deformation measurements. We compared results from the “GPS tide gauges” based on multipath observations and conventional tide gauges during the period from 2012/6/1 to 2012/7/31 at 34 coastal GPS stations, and showed that some of these GPS stations could be used for measuring SSH. For example, SSH measured with Satellite 7 at the Okinawa tide gauge station was accurate to ˜27 cm. This is somewhat lower than those reported in previous works possibly reflecting the longer sampling interval.
