A desirable feature in gliders is the ability to be both mobile and bottom-resting as gliders today must remain in constant motion. A mobile to stationary conversion will allow a traditional, bottom mounted sensor platform to be deployed from over the horizon, covertly move into position, and then become a bottom fixture. Webb Research is currently developing a mobile, ellipsoidal glider with bottom-resting capabilities. A vehicle of lenticular shape (see figure), having low drag in the horizontal bottom current, can have a rugged exterior to resist buffeting due to bottom currents.
An article on this vehicle entitled "Design of a mobile and bottom-resting autonomous underwater gliding vehicle" can be found in the Proceedings of the Unmanned
Underwater Submersibles Technology 2003 conference .
