Autonomous Surface Craft
A small autonomous surface craft was developed to monitor sub-surface activity as part of a Defense Advanced Research Agency (DARPA) program. Our responsibility was the communications and control systems. A five-processor board was developed with each processor responsible for a key subsystem of the craft. The craft is required to motor to it’s specified deployment location and maintain it’s position using thrusters and an inertial navigation system with GPS. A sub-surface microphone monitors underwater activity while a satellite data connection relays the information to a land-based station. The unit is powered by lithium-ion batteries which are recharged by a solar power system and a wave driven generator.
