UNDERWATER GPS G2

Underwater GPS G2

Worlds most robust positioning system!

- 100 or 300 meter range

- Quick deploy antenna

- Unbeatable price/performance

OPERATING PRINCIPLE

You can choose between using a compact antenna or separate cabled receivers as your receiving baseline.

The antenna is quick and easy to set up while the separate receivers will enable very flexible designed baselines. Both supports the full 200 meter range.

1. Locator

The Locator transmits an acoustic signal which are picked up by the Receivers

2. Baseline

The antenna or separate receivers picks up the acoustic signal from the Locator

3. Topside

The topside positioning computer uses advanced algorithms to triangulate and calculate the position of the Locator based on the received signals from the antenna/receivers

RANGE

R100 or R300

Underwater GPS G2 comes in two different range versions; R100 and R300 whereas the number indicates the range in meters between the Locator and Antenna/Receivers.

Cylindric Area

The operational area is designed as a cylinder with a radius of 100/300 meter and a depth of 100/300 meter.

Hard Limit

The 100/300 meter range is a “hard limit”, meaning that once the Locator moves outside that range, the position will not be calculated.

Acoustic + Software

The range is limited by the acoustic signal from the Locator and the software running on the Master-D1 positioning computer.

LIMITING THE SEARCH AREA

If you know you won’t need the full cylindric search area, it is beneficial to the performance of the system to apply some limits.

Limiting Range

You can reduce the radius of where the system will search for the locator.

This is a great idea if you are operating in a confined space like water tanks, pools, fish cages or similar.

Reducing the range even in the open ocean may give you a better performance on short distances.

Limiting Area

You can limit which part of the cylinder you want to operate within.

This should be done if there are obstacles like land or other no-go places for your ROV.

Reducing the area even in the open ocean may give you a better performance.

Limiting Depth?

It is not possible or needed to limit the depth. All Underwater GPS systems relies on a separate pressure sensor to provide the depth of the locator.

FULL FEATURED GUI

All Underwater GPS systems comes with a pre-loaded Graphical User Interface (GUI).

The GUI runs on the Master-D1 positioning computer and is accessed through a standard web browser.
