Sublocus is an underwater inertial navigation system that provides accurate position, velocity and orientation at depths of up to 3000 metres. It features high accuracy north seeking fibre optic gyroscopes, accelerometers, an internal GPS receiver and a pressure depth sensor. It accepts external aiding from speed logs, propeller speeds, DVLs, USBLs, SBLs and LBLs.
Sublocus是一个水下惯性导航系统，在高达3000米的深度提供准确的位置、速度和方向。 它具有高精度寻北光纤陀螺仪、加速度计、内部GPS接收器和压力深度传感器。 它接受来自速度、螺旋桨速度、DVL多普勒、USBL超短基线、SBL短基线和LBL长基线等外部辅助输入。
Sublocus features very high performance inertial sensors combined with Advanced Navigation's revolutionary fusion algorithms. This allows it to provide highly accurate position, velocity, roll, pitch and heading. Sublocus can provide underwater position accuracy of 0.08% distance travelled.
Sublocus is a fully integrated navigation system and features both a pressure depth sensor and GPS receiver built in. It is supplied with a 6000 metre depth rated GPS antenna. The GPS receiver provides accurate pre-dive starting position without the hassles of surveying and manual entry.
RAPID NORTH SEEKING GYROCOMPASS快速寻北陀螺仪
Sublocus features an extremely fast north seeking algorithm that is able to provide accurate heading in as little as 10 seconds after power on from a hot start and 10 minutes from a cold start. Sublocus's north seeking algorithm runs continuously while in operation and is not effected by velocities or angular movements.
Sublocus has been designed from the ground up for mission critical control applications where reliability is very important. It's software is built on top of a safety oriented real time operating system and it is designed and tested to safety standards with fault tolerance in place. The electronics are isolated and protected from reverse polarity, overvoltage, surges, static and short circuits on all external interfaces.
Sublocus's enclosure is machined from a single block of high grade titanium and it has only one triple sealed join. It is polished to make it resistant to biofouling. Sublocus uses FOG technology which means there are no moving parts.
Sublocus has support for a wide range of peripheral inputs including speed logs, propeller speeds, DVLs, USBLs, SBLs and LBLs. If Sublocus doesn't support the peripheral device you have, we will add support for it free of charge.
OIL AND GAS石油与天然气勘探
Sublocus can save significant money when used on ROVs in the oil and gas industry. Sublocus allows ROV operators to drive directly to underwater structures without having to search for them, saving time and money. Additionally the spatial awareness that Sublocus provides the operator allows for faster and safer operations with a lower risk of collisions.
Sublocus is ideally suited for oceanography and underwater surveying. It provides high accuracy absolute positioning which allows the user to map subsea features. Additionally the high accuracy orientation it provides allows for geotagging of projected camera footage.
AUTONOMOUS UNDERWATER VEHICLES自主水下机器人
Sublocus is an excellent choice for navigation of autonomous underwater vehicles. It's high accuracy and safety conscious design makes it ideal for control use. It provides the ability to perform stationkeeping, obstacle avoidance and fully autonomous waypoint control.
Sublocus is an excellent reference for underwater research vehicles. It's extensive peripheral support and guarantee to add support for any new peripheral means that experimental sensor technologies can be integrated in Sublocus's solution.
