Description
A complete positioning system!
The G2 Topside is connected to the G2 Antenna, which must be mounted in the water with a direct line of sight to the Locator. A Wi-Fi signal emitted by the internal Web server of the G2 Topside allows the user to track the Locator using the Water Linked Web-based GUI.
With the benefit of an integrated GPS and Inertial Measurement Unit (IMU), the GPS G2 provides the absolute GPS position of the Locator, removing the need to integrate additional third-party sensors for accurate navigation.
The G2 system is custom configured at the time of order to fit best the specific needs of the user and the target being tracked, as well as whether a 100m or 300m operating range is required.
The standard G2 system is supplied with a battery-powered U1 Locator, allowing the G2 system to track any target (i.e. ROV or Diver) and does not require the Locator to be integrated, just physically attached to the target.
