AUV | ROV Sensors: AUV | ROV Sensors
Autonomous and remotely operated underwater vehicles are rapidly evolving to fill scientific niches, many with capabilities otherwise unattainable through traditional manned research at a fraction of the operating cost. Sea-Bird Scientific offers a line of sensors uniquely designed for integration with various unmanned underwater vehicles, expanding data potential and opening new doors for unique research opportunities. While Sea-Bird Scientific originally designed most sensors for stand-alone applications, we have redesigned and miniaturized popular product lines meet the specific operational requirements of unmanned research platforms: a 1 kg CTD can now replace a 10 kg CTD while maintaining the same accuracy, and a precision optical sensor can now take up half the space while recording the same data channels.
