Greensea Systems, Inc. products

An integrated SOF system that supports complex tasks in hostile conditions. With the RNAV2, combat divers can offload navigation and vehicle operation to the supervised autonomy of STIDD Diver Propulsion Device (DPD), providing a safer and more productive mobility system. Add the OM2 (optionally manned) accessory to allow unmanned transit to or from predetermined locations for INFIL/EXFIL. Missions can be pre-planned and updated on the fly. Thumb knobs and finger triggers are used to control the vehicle and operate the interface. The diver’s hands never have to leave the handgrips to monitor progress to a destination, system status, alarms, or even reroute the vehicle.

Modifiable commercial inertial navigation systems optimized for specific applications. The INSpect GS Inertial Navigation Systems (INS) can be modified to optimize performance for diverse, complex operational scenarios where there are size, weight, power, and cost (SWaP-C) constraints. A product of over a decade of development and testing, the INSpect GS line features Greensea’s proprietary Kalman estimation algorithms, which fuse data from available navigation aiding sensors and filter out noise and outliers to deliver stable and accurate navigation estimates. Meanwhile, Greensea’s patent-pending autonomous heading alignment algorithms ensure the best navigation performance for any operational scenario.

Modifiable ROV control systems deliver highly-stable, fully-integrated systems for work-class and inspection-class vehicles. From controlling complex deep ocean work-class ROVs to providing precise navigation and stability for miniature ROVs used in explosive ordnance disposal, Greensea’s integrated control systems are designed for work. By leveraging the proven, modular, OPENSEA platform, Greensea’s ROV systems can be designed and deployed quickly and robustly. Control packages are available at basic and professional levels.

Safe C2 extends Greensea’s current navigation, command, and control systems installed in thousands of ROVs around the globe including the current US Navy EOD SeaBotix vLBV ROV, the Next Generation EOD Underwater Response Vehicle, and workclass ROVs. Supporting a wide range of COTS data links, Safe C2 is technically viable for the expeditionary maritime EOD CONOPS, and operationally viable for conducting advanced intervention tasks with ROVs. The technology hurdle addressed in Safe C2, which makes the long range control of a ROV practical, is handling of the data stream back and forth between operator and vehicle. Safe C2 manages the data stream by transmitting the least amount of data necessary and sychronizing data so that even with slight delays, the sonar and video will remain in synch when the operator sees them.
