Mechanical Features

Low-profile IP67 rugged housing

The IP67 rated housing is made of sturdy ABS/Polycarbonate plastic to survive bumps and knocks and is UV stabilised to survive many years in the sun and weather. Its low-profile makes it easier to mount in the corrugation on containers or to conceal on the underside of a trailer.

Operating temperature

-20°C to +60°C

The device will operate in temperatures outside this range but battery life will be reduced

GPS Tracking

GPS Module

High sensitivity assisted GPS receiver, 72 channel

Antenna with LNA Boosted by low-noise amplifier (LNA) allows operation in "urban canyons" and container stacks



Sleep Current

5µA (micro-amps)


3 x AA Size 1.5V batteries – alkaline or lithium. Alkaline – industrial type recommended.

1.5V Lithium – longer life and wider temperature range

Recovery Mode Switch from Daily Locate to Live Tracking over- the-air
3D Accelerometer The 3 axis accelerometer allows the Oyster to “sleep” in an ultra-low power state yet still wake up when movement occurs
Adaptive Tracking Adaptive-Tracking technology enables the accelerometer and GPS data to be used intelligently to work out if it is moving and to send frequent updates, as well as to scale the update rate down to once per day if the asset is stationary in order to preserve battery life
Autonomous Aiding Data

Predicts satellite locations Reduces the time to first fix

Improves performance in "urban canyons"

Sigfox is new radio technology that allows devices to transmit small messages over long range using low power.

Sigfox is rolling out a global network and provides a more competitively priced option for devices to connect to the Internet of Things (IoT).

Digital matter is developing a range of IoT devices that will operate on the Sigfox network.
