Remote Sensing and Internet Data Sources Unit 3: Module 12, Lecture 3 – Remote Autonomous Vehicles/On-line data resources

Developed by: Host Updated: U3-m12-s2 Subsurface vehicles and sensors  In large water bodies, towed or autonomous vehicles can be used to record data over large areas  Towed systems  Remotely operated vehicles  Autonomous vehicles  These use a combination of remote sensors (Sonar, hydroacoustics) and probes (on-board sensors)
