Compact Long-Life Battery-Powered GPS Asset Tracking


The Oyster is a compact, rugged GPS tracking device that has been designed for tracking containers, trailers, skip bins, and other assets where super-long battery life is required without sacrificing the frequency of updates and performance.

The IP67 rated housing is rugged and UV stable, so the Oyster can be mounted on assets that are exposed to rain, dust and marine conditions.

By utilising the latest technology, the Oyster can operate in ultra-low power modes, and with an incredible battery life of up to 7 years the Oyster Sigfox can be attached to assets and tracked without needing to change batteries. The Oyster has built-in antennas for GPS reception and for Sigfox communication, a 3D accelerometer, a high-performance GPS that can track both GPS and GLONASS satellites simultaneously and flash memory for storing non-volatile information.

The Oyster Sigfox uses the Sigfox network to give you coverage of your assets at a low data cost. The Oyster Sigfox is available for RCZ1 (Europe and Middle East), RCZ2 (North America and Brazil) and RCZ4 (Australia, New Zealand, South America, Hong Kong, South East Asia).

The Oyster Sigfox uses 3 x AA 1.5V “off the shelf” Lithium batteries. These are generally available at retail outlets from manufacturers like Duracell and Energizer. Industrial 1.5V Lithium AA batteries are also available at bulk pricing.

The Lithium batteries have excellent performance and capacity, and allow the Oyster Cellular to be used in extreme temperatures and climatic conditions that other tracking devices simply cannot operate in.

  • IP67 Rugged weather-proof housing
  • Fully powered by 3 AA consumer batteries
  • Up to 7 years tracking on Sigfox low cost network (once daily)
  • Small, Compact and easy to install and conceal

  • Hardware Features

    Low-profile IP67 rugged housing

    The housing screws together for easy assembly, and has 2 convenient mounting tabs. It also has ‘strap slots’ allowing the Oyster to be cable tied or metal strapped to an asset. It is low-profile making it easier to mount in the corrugation on containers or concealed on the underside of a trailer, for example.

    Dimensions: L 137 x W 72 x H 30mm
    Weight: 160 grams with batteries


    AA size:
    The Oyster uses 3 x “AA” size 1.5V Lithium batteries which provide a balance between size and capacity

    Off-the-shelf Lithium:
    The Oyster Sigfox must be fitted with off-the-shelf 1.5V Lithium batteries. These are readily available from retail outlets, for example Duracell and Energizer.

    Sleep Current:
    10uA (micro amps)

    Battery Life with Adaptive-Tracking

    The Oyster can be set to use Adaptive-Tracking technology where the accelerometer and GPS data are used to intelligently work out if it is moving and to send frequent updates, and to scale the update rate down to once per day if the asset is stationary - to preserve battery life.

    7 years @ one position per day (at 25°C).

    Operating Temperature

    -20°C to +60°C

    For operation in extreme temperatures, the Oyster must be fitted with Lithium batteries. Batteries are affected by temperature extremes and typical performance is dependent on temperature.

    High sensitivity GPS

    • Supports concurrent GPS and GLONASS
    • 72 channel high sensitivity receiver
    • -167dBm industry leading tracking performance
    • Optimal hot-start performance.
    • AssistNow Offline aiding data for fast time-to-first-fix and performance in urban canyon environments


    The Oyster uses both the GPS and GLONASS positioning systems simultaneously. This allows the device to use twice the number of satellites to get a position fix – making it faster and more accurate.

    Low Noise GPS Amplifier (LNA)

    GPS signals are boosted by a special low-noise amplifier (LNA). This allows the Oyster to operate where normal units will fail to receive GPS signal – like in a container stack!

    Sigfox Communications

    The Oyster uses a high power radio transmitter / receiver that operates on the Sigfox network, and is available in variants for the various Sigfox Zones around the world.

    • RCZ1 Europe and Middle East
    • RCZ2 North America and Brazil
    • RCZ4 Australia, New Zealand, South America, Hong Kong, South East Asia


    Sigfox Class 0: Best radiated power. Device will work perfectly well in all covered areas, indoor and outdoor.
    RC1: CE, ICASA
    RC4: RCM, CE

    Internal Antenna

    Internal GPS and Sigfox antennas tuned by the RF laboratories to ensure optimal performance.

    3 Axis Accelerometer

    The 3-axis accelerometer allows the Oyster to ‘sleep’ in an ultra-low power state yet still wakeup when movement occurs.

    Flash Memory

    The flash memory is used to store data, parameters and other important information that needs to be securely stored.

    Configuration Cable

    The Oyster Sigfox caters for a USB configuration adapter and cable, which is used to program firmware updates and configuration information on the device.
  • The Oyster is a stand-alone tracking unit and therefore does not have peripherals available.

  • Firmware Smarts

    Sigfox Data Management

    The Oyster Sigfox device manages the data plan that it is configured for to maximise the use of the allocated Sigfox data messages

    OTA Configuration

    The Oyster can be remotely configured and some of the key operational parameters updated via the Sigfox downlink messages (your data plan needs to support downlink messages).

    AssistNow Autonomous Offline

    The Oyster will track successfully where other devices just give up.

    This fantastic technology allows the GPS to predict which satellites are in orbit above it and to dramatically reduce the time-to-first-fix of the GPS, and the overall performance of the GPS, especially in ‘urban canyon’ or forested environments.

  • Software and Data Managment

    Data from the Oyster Sigfox device is sent via the Sigfox cloud infrastructure to the back-end server platform for processing and reporting.

    This can be Digital Matter’s Telematics.Guru platform which has built-in support for the Oyster Sigfox device and protocols, or to your own server platform. Please contact Digital Matter if you require information on the integration of the Oyster Sigfox data formats.
