Underwater Glider Reliability and Implications for Survey Design
It has been 20 years since the concept of the Autonomous Ocean Sampling Network (AOSN) was first introduced. This vision has been brought closer to reality with the introduction of underwater gliders.While in terms of functionality the underwater glider has shown to be capable of meeting the AOSN vision, in terms of reliability there is no communitywide hard evidence on whether persistent prese...
متن کاملDesign of an underwater glider platform for shallow-water applications
Underwater gliders are type of autonomous underwater vehicle that glide by controlling their buoyancy and attitude using internal actuators. By changing the vehicle’s buoyancy intermittently, vertical motion can be achieved. Characteristic of glider motions include upward and downward in a saw tooth pattern, turning and gliding in a vertical spiral motion glides without using thrusters or prope...
متن کاملUnderwater Glider Dynamics and Control
In this work, we build on our earlier results and accomplishments in understanding, modeling and controlling underwater glider dynamics (YIP Grant # N00014-98-1-0649). The focus is on dedicated gliding vehicles that have the ability to change mass (or volume) for buoyancy control and to redistribute mass (and possibly control a rudder) for attitude control. The framework consists of a dynamical...
متن کاملUnderwater Glider Networks for Adaptive Ocean Sampling
The long-term goal of this research is to enable a cooperating group of underwater gliders to perform efficiently and robustly as an autonomous, adaptive sampling network in a three-dimensional, dynamic ocean environment. This will involve developing the mathematical infrastructure and design tools for effecting feedback-controlled, schooling-like network behavior in an unsteady flow field whil...
متن کاملTerrain-aided Navigation for an Underwater Glider
A terrain-aided navigation method for an underwater glider is proposed that is suitable for use in ice-covered regions or areas with heavy ship traffic where the glider may not be able to surface for GPS location updates. The algorithm is based on a jittered bootstrap algorithm, which is a type of particle filter that makes use of the vehicle’s dead-reckoned navigation solution, onboard altimet...
