Japan Coast Guard has been operating Autonomous Ocean Vehicle (AOV), which is Wave Glider made by Liquid Robotics and equipped with a GNSS antenna, an ADCP, a weather station, a wave sensor and a CTD, since 2016. We operate the AOV for one year in five square kilometer area for continuous meteorological and oceanographic observation and provide the observed data via our web site. The AOV moves forward by converting wave energy to propulsion and utilizes solar energy as a power source for sensors. In this presentation, we report the problems and improvements of the continuous long-term observation involved with the limited propulsion force and power source. In addition, we present GNSS observation for precisely determining the chart datum and observation of a typhoon.
