Overview

Last updated 3 months ago

The ROV Locator is designed for low-cost, medium accuracy localization of underwater objects.

  • The system can be used to guide an ROV to an area of interest, either manually or autonomously

  • The system can be used to locate an ROV or AUV

  • Other applications, such as swarming, are also possible

This system is designed and priced for use by people who need to know generally where their ROV is located. It is not intended to be a survey-grade instrument, and it has few features not directly required for the primary function.

A minimum complete system requires both a transmitter or transponder and a receiver or transceiver.
