Built-in Battery Module

1. Rechargeable lithium battery 24V*3.5A; external charger 1pc, full 90% power time <3 hours;

2. Continuous receiving and transmitting endurance time > 12 hours;Standby endurance > 3 months.

Sensor Access Module

1. Up to 2 external instruments can be supplied with power to support the reading;

2.Data from instruments , forwarded to the water surface unit.

Long Baseline Positioning

Supports receiving PPS signal input , calibrates the internal clock , can be used as a primitive for LBL.

External Release Unit Interface

Provide external interface can be connected with external release device, as the communication and power components in the releaser, after adding the release device can be composed of the releaser.

Hydro-acoustic Positioning Beacon

With a high-precision depth sensor, the communication signal can be used for hydro-acoustic positioning at the same time, and can be used as a hydro-acoustic positioning beacon.
