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.

<10µA (micro-amps)



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

1.5V Lithium – longer life and wider temperature


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"



GPS Module

High sensitivity assisted GPS receiver, 72 channels


Setup by USB Cable and OTA

Antenna with LNA


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