The ROV Locator Mk II brings the cost-effectiveness of underwater positioning solutions to a new level. With a 300m depth rating and no need to calibrate crystal oscillators or manually sync the distance between units (select auto sync) at mission start-up, you can get up and running in no time.
The ROV Locator Mark II includes a transmitter mounted on the ROV and a receiver module located on the surface. The bundle also comes with a mounting ring and adapter. Simply power up, start the dive and track the ROV location in real-time on the QGroundControl map display. Serial communication and API are available.
Autosync works by exposing the Receiver and Transmitter to GPS or GNSS signals at the start of the mission and optionally at intervals during the mission. Satellite acquisition occurs typically within 30 seconds of power-up. In the canonical case of a ROVL receiver sited near the ROV operator and a ROVL transmitter on the ROV, the satellite acquisition will typically occur in the background, and at the time the ROV is being readied for launch and while the ROVL Receiver IMU calibration is being done.
