Locator-S1
Description
The Locator-S1 carries an internal GPS based time sync module. Because of this, the S1 does not require tether integration for top-side communication. It only requires external power 10-18V to be provided from the underwater device.
Some Locator-S1 attributes can be configured using an integrated UART (3V3) 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. Once the Locator-S1 has lock it can operate for approximately 6 hours befor needing resync with GPS.
Note
The default channel for Locator-S1 is 17 on boot.
Locator-S1 supports channel 16,17 and 18.
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.
LED Signals
-
No green light: Power is off and the unit is not ready for diving.
-
Flashing green light (once a second): Searching for GPS lock. The unit is not ready to dive.
-
Fixed green light: GPS lock is achieved. The unit is ready to dive.
-
Flashing green light (slow): GPS lock has been acheived but lost. The unit is ready to dive.
