TRIG can continuously track the precise location of isolated workers anywhere in the world, including oceans, deserts and polar regions.

A pocket-sized tracker / responder which uses GPS technology and the Iridium satellite network can provide an emergency lifeline in the extreme environments experienced in the oil and gas industry.

Developed by Trident Sensors, TRIG can continuously track the precise location of isolated workers anywhere in the world, including oceans, deserts and polar regions. It can also be mounted on vehicles, lifeboats and aircraft etc. The units can be tracked live using mapping software such as Google Maps or other GIS tracking software.

An alert function allows the user to signal for assistance at the touch of a button in the event of an emergency. The user has the reassurance of knowing that a controller has acknowledged the alert when TRIG's LED display changes to blue.

In routine use, the rugged unit can be used to send and receive data and text messages, enabling two-way communication from any location on Earth, no matter how remote or inhospitable. The data can be sent to email addresses, mobile phones, websites or other remote stations.

The Bluetooth-enabled TRIG can link wirelessly to a smartphone, laptop or other Bluetooth device, making it simple to send and receive emails and SMS messages. The linked device can also act as a display and carry out data processing functions if required.

TRIG's advanced electronics ensure that the rechargeable unit has a long battery life. No larger than a smartphone, it weighs less than 250g and is dustproof and waterproof to IP68.

The deep-sea version of TRIG can be used for surface tracking and control of remotely operated vehicles (ROVs) and autonomous underwater vehicles (AUVs) and can withstand pressures up to 1380 bar (20 000 psi). The system can also transmit mission data and can be used to reprogram the vehicle for the next mission.

Trident Sensors trackers make use of the Iridium constellation of 66 satellites to provide two-way communication from anywhere in the world, including the polar regions. This is possible because the Iridium satellites are in polar orbits, unlike rival systems which do not pass over higher latitudes or are in geostationary orbit.

Notes to editors

Trident Sensors was founded in 1997 to produce oceanographic instruments and sensors. Its business has since expanded to concentrate on live GPS and two way data transmission using the Iridium constellation of satellites. A winner of the Queen's Award for Innovation in 2011 for its tracking products, the company designs its own hardware, firmware and software.
