Underwater GPS (UGPS)
Explore more of the subsea world with full confidence in the positioning data you receive with the Underwater GPS. With our purpose-developed positioning technology, unwanted noise no longer affects positioning accuracy the way it traditionally has with underwater positioning solutions.

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 flexibly designed baselines. Both supports the full 300 meter range.
Locator – The Locator transmits an acoustic signal which are picked up by the Receivers.
Baseline – The antenna or separate Receivers picks up the acoustic signal from the Locator.
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.
R100 or R300
The Water Linked Underwater GPS comes in two different range versions; R100 and R300 where the number indicates the maximum 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 meters and a depth of 100/300 meters.
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 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.
