Description

The Locator-S1 is a digital hydro acoustic locator device with an internal GPS based time sync module.

The Locator-S1 does not require tether integration for top-side communication. It only requires external power 10-18V to be provided
from the underwater vehicle. Time-sync with the top-side is achieved using its internal GPS. That makes it perfect for integration with ROVs that don’t have an extra twisted pair in their tethers, such as a BlueROV2 with the Fathom Slim tether, or for fiber optic tethers.

As the Locator-S1 does not carry its own depth sensor, the depth needs to be provided from the underwater vehicle (ROV etc.) to the topside Master-D1 using the software API. Example of how to perform this can be found here.

This integration is already done if using an ArduSub vehicle (like the BlueROV2).

Some Locator-S1 attributes can be configured using an integrated I2C interface. This configuration is optional and not required for
normal operation.

Before deployment in water, the Locator-S1 needs to achieve a GPS lock. The integrated status-LED shows the condition of the GPS lock.

It comes standard with a 1 meter cable (with preinstalled cable penetrator) for easy integration with ROVs like the BlueROV2.

Benefits:

• GPS based sync removes all tether requirements enabling very easy integration with any ROV.
• Extremely small size making it perfect for even the smallest underwater vehicles.
• Highly robust operation in areas with reflections (shallow water, around installations etc.)
