Simulator

The SIS Simulator is capable of modeling a complete real world environment, including sensor simulation, and vessel simulators, for both USVs and target craft

The Sensor Simulator can model a variety of sensors, including radar, sonar, and AIS. Development during the ACTUV project allowed the Sensor Simulator to follow virtual submarines using two different sonar systems and radar.

The USV simulator has gone through multiple generations and is constantly improving. Generation 1 simply calculated a latitude and logitude from a given speed and heading. Generation 2 was developed under the ACTUV anti-submarine warfare project. This version added in wave motions into the environment and could simulate the IMU of the craft. The third and current generation of the USV simulator uses complex wave algorithms and graphics engines to provide a more realistic model, complete with towed bodies.

The simulator connects to the CARACaS autonomy software to simulate autonomous behaviors using only a simulated environment.

Complete Simulation

A complete simulation. The USV is following a submarine who is trying to evade capture. A decoy and surface vessels are used to throw the simulated USV off track.

The red circle is a confirmed submarine, the yellow squares are unknown surface contacts.
