In ocean bathymetry, the instantaneous depth measured by survey ships or by unmanned surface vehicles (USVs) cannot be directly taken as the chart depth because of the effect of waves and the tide. A novel ocean bathymetry technology is proposed based on the USV, the aim is to evaluate the potential of the USV using a real-time kinematic (RTK) and a single beam echo sounder for ocean bathymetry. First,...
Collision avoidance (CA) for an Unmanned Surface Vehicle (USV) is a key technology for autonomy especially in a complex environment. To decide a suitable steering occasion to maneuver for the CA of an USV may be very helpful in some applications such as the long-term monitoring task in the environment with various obstacles. In this paper, a steering occasion strategy is designed. Firstly, a feasible...
Unmanned Surface Vehicle (USV) is a novel kind of oceanic platforms, which is potential to be an effective platform for acoustic applications. Active and passive underwater acoustic experiments using our USV called USBV at Ji-hong-tan reservoir in Qingdao on July 15–17, 2015 and at Wu-zhi-zhou Island in the South China Sea on January 3–6, 2016 are presented to quantify this potential. The acoustic...
