SUBLOCUS DVL 带多普勒速度记录仪水下导航系统
Sublocus DVL is an underwater acoustic and inertial navigation system that provides accurate position, velocity and orientation at depths ofSublocusDVL水下导航与多普勒速度记录仪 up to 3000 metres. It features a doppler velocity log, 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, USBLs, SBLs and LBLs.
Sublocus DVL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。 它具有多普勒速度记录仪、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 DVL 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 DVL can provide underwater position accuracy of 0.08% distance travelled.
Sublocus DVL is a fully integrated navigation system and features a doppler velocity log, pressure depth sensor and GPS receiver built in. It is supplied with a 3000 metre depth rated GPS antenna. The GPS receiver provides accurate pre-dive starting position without the time and hassles of surveying and manual entry.
RAPID NORTH SEEKING GYROCOMPASS快速寻北陀螺仪罗盘
Sublocus DVL 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 DVL's north seeking algorithm runs continuously while in operation and is not effected by velocities or angular movements.
Sublocus DVL 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 DVL's enclosure is machined from a single block of high grade titanium and it has only two triple sealed joins. It is polished to make it resistant to biofouling. Sublocus DVL uses FOG technology which means there are no moving parts.
Sublocus DVL has support for a wide range of peripheral inputs including speed logs, propeller speeds, DVLs, USBLs, SBLs and LBLs. If Sublocus DVL 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
Sublocus DVL can save significant money when used on ROVs in the oil and gas industry. Sublocus DVL 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 DVL provides the operator allows for faster and safer operations with a lower risk of collisions.
Sublocus DVL is ideally suited for oceanography and underwater surveying. It provides high accuracy absolute positioning and altitude 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 DVL 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 DVL 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 DVL's solution. Additionally Sublocus DVL provides water current measurements which can be useful for research on ocean life.
