Extra large unmanned underwater vehicle (XLUUV) systems are being developed world-wide in support of submarine operations. This new breed of UUV is intended to run for months at a time, unsupervised and holding much larger payloads than traditional UUVs have been used to. The new missions present a new set of challenges to the UUV designer and their operators. XLUUVs need to compute their navigation solution while remaining submerged for extended period of times. They must also communicate while remaining covert. Instruments usually found across the smaller UUV fleets are not typically ready to meet these set of requirements. We offer a range of COTS instruments which can be readily integrated into these systems in support of their mission requirements.


We are the leading developer of hybrid acoustic-inertial instruments. This new type of instrument brings together a number of sensor technologies to provide best-in-class navigation solutions. SPRINT-Nav has become the product of choice for developers of large and extra-large UUVs the world over. The new SPRINT-Nav X modality offers unprecedented levels of performance in a UUV friendly form-factor (less than 1 nautical mile error for every 12 hours of simply unaided inertial navigation and better than 2 m error for every 10 km travelled with Doppler lock) . This means any XLUUV can navigate for extended durations under dead-reckoning, needing to surface fewer times for a GPS fix.


Close to shore, and in friendly waters, the XLUUV may be required to communicate with a surface asset. Our Ranger 2 and AvTrak 6 are the perfect compliment for this part of the mission. Already deployed across a myriad of UUVs in all continents, Ranger 2 can be used to both track and communicate with the XLUUV at all ocean depths. Since the AvTrak 6 enables the UUV to remain covert should it wish to there is no risk of the XLUUV falling into the wrong hands.


Our Gyro iUSBL is a one of kind inverted USBL that enables a UUV to take a bearing, elevation and range measurement from any 6G (Sonardyne sixth generation) beacon across all ocean depths. It can be used to enable precise homing operations over a number of kilometres. The XLUUV can find its way to a docking station, a forward-deployed outpost or a network of sensors and when in reach it can use free space optical modems like BlueComm 200 to upload large volumes of data (up to 10 Mbps).
