Abstract:
Unmanned vehicles may provide more time- and cost-effective methods of gathering hydrographic survey data when compared to traditional, manned survey vessels. A remote-controlled unmanned surface vehicle (USV) was outfitted with a depth transducer for the purpose of conducting a depth survey of the Charles River Basin. Two windsurfer fins were added to the stem of the USV kayak for directional stability without significant drag, permitting a maximum vessel speed of 4.4 knots. A total of 1485 latitude-longitude GPS points with corresponding depth measurements were taken. Charles Basin data was plotted with ArcGIS software and used to create depth contours and three-dimensional surface plots of the river bottom. This prototype survey USV displays promise and could become readily feasible with further development and autonomy.
