The world of autonomous underwater vehicles (AUV) is seeing a growing trend toward resident vehicles, longer missions, and greater depths. These drivers mean that the need for reliable positioning and robust communications to underpin situational awareness of these vehicles is critical, and operators are becoming increasingly demanding of the functionality required to meet these new challenges. Sonardyne has been a pioneer in developing underwater positioning and communications solutions for the most demanding scenarios, which individually are class leaders, but when combined offer game-changing capabilities for autonomous operations. With the capability for rapid calibration-free mobilization onto a vessel, the Ranger 2 gyro ultra-short baseline (USBL) positioning and telemetry system is already proving its worth on unmanned surface vessels (USV) used for AUV tracking. This is complemented by the SPRINT Inertial Navigation Systems (INS), which when tightly integrated with Syrinx 600kHz Doppler Velocity Log (DVL) in an AUV, provides not only high levels of precision, but also redundancy that minimises the risk of mission abort or vehicle loss. Autonomous operations can be further enhanced by the BlueComm optical communications system, with bandwidths that enable new applications such as rapid data transfer to an AUV during a “fly-by,” and the low power AUV-optimised Solstice sidescan sonar provides high resolution, co-registered imagery and bathymetry.
