Navigation, Localization, and Pose Estimation
The OPENSEA platform includes a flexible navigation and localization engine with multiple navigating modes for different conditions, environments, and tasks. All Greensea navigation systems are optimized for size, weight, power, and cost (SWaP-C) restrictions while providing extremely accurate navigation that absolutely georeferences and locates the vehicle. Designed to be customizable by application, the technology supports manual navigation sensor fusion to enhance the ability to make the decisions that are right for any given situation.
Greensea’s navigation achieves optimal results by using a cascaded navigation estimation methodology. The estimation algorithm identifies compromised sensor data and chooses the best combination of sensors to optimize the solution. It also supports manual sensor fusion for situational decision making. Greensea navigation products are currently used in challenging environments such as highly dynamic diver mobility platforms, and tank inspection and hull inspection which require alternative navigation coordinate frames.
