Simulator for RNAV2

Simulator for RNAV2 Prepares Operators in a Virtual Underwater Environment

RNAV2 provides navigation, control, communications, and autonomy for the Diver Propulsion Device (DPD) sold and manufactured by STIDD and is in use by SOF programs around the world. RNAV2 runs Greensea’s SOF Workspace and open architecture navigation, mission planning, and vehicle control software platform developed for SOF combat swimmers based on OPENSEA┬«.

The RNAV2 Simulator provides a powerful training tool to develop and maintain proficiency with RNAV2 without utilizing actual RNAV2 hardware or requiring in-water activities. With controls that closely mimic RNAV2 and the same software as RNAV2 running on a laptop, users experience realistic navigation, sonar, mission planning, and DPD simulation.

Practicing and training on missions within the simulator replicates actual CONOPS with the mission planning software. Trainers can specify starting coordinates, environmental conditions such as time of day, surface conditions, current, and turbidity. Each scene is typically 2km x 2km and includes seeded mine targets to facilitate operators developing sonar proficiency and object detection.


Based on a high-fidelity physics engine with an accurate hydrodynamic model of the DPD and using real world bathymetry and satellite data, simulated raw sensor data is provided to RNAV2 as operators maneuver in the virtual world. Simulation happens at the raw sensor level to fully utilize the software platform of RNAV2. Operators can accurately exercise all functions of RNAV2 including pre-dive checks, mission planning, initialization, alignment, sonar, and autopilots.

The RNAV2 Simulator provides a powerful and comprehensive means for operators to maintain proficiency, train, and evaluate operational scenarios on their own laptops without going into the water. The simulator uses the exact software as RNAV2 and the identical embedded processor creating a convenient means to evaluate new software releases, demonstrate the functions of RNAV2, and even practice failure scenarios.

The RNAV2 Simulator software with user-license dongle, high quality gaming computer tested to provide the best simulator experience, and a. computer carry case.
