Modification of a military grade glider for coastal scientific applications

Exocetus Development, LLC of Anchorage Alaska has recently purchased the assets, IP, and manufacturing technology for the ANT Littoral Glider [now called the Coastal Glider] developed with ONR funding during the past 6 years. The glider technology developed under this program is now being modified to be more readily deployed in near coastal scientific applications. The glider is capable of self-ballasting from essentially fresh to full ocean water, and has a variable speed capability to allow it to handle near shore currents up to 2 knots. The glider is currently being modified to include a dedicated science computer and improved communications and survivability. This paper describes the prior and current development of this vehicle, describes the vehicle's capabilities and specifications, discusses initial applications, and describes plans for future development. Additionally, some of the testing conducted during the past two years by GA Tech, NPGS, NUWC-Newport, and KORDI in Korea is presented.
