-ArduSub maintains the same [GPS module drivers](https://ardupilot.org/copter/docs/common-positioning-landing-page.html) as the rest of the ArduPilot family of firmwares, so a compatible GPS module may be directly connected to the GPS port on the autopilot. Positioning information will only be available when the vehicle is on the surface and the module is out of the water. The module will not be able to obtain a fix if it is underwater due to high frequency radio waves being unable to penetrate the water medium.

 Multibeam imaging sonars are similar to mechanically scanning sonars in that they acoustically image targets in a top-down 2-dimensional representation. However, with multiple sonar beams the refresh rate is much higher presenting a real-time image of what is in front of the vehicle.
