Sting Long-Life Rechargable GPS Tracker


The Sting is an ultra-compact, rechargeable GPS tracking device. The light, temperature and humidity sensors set it apart from other battery powered trackers. It has been designed to track high value parcels, cargo, cash in transit, personnel, and other assets where super-long battery life is required without sacrificing the frequency of updates and performance.

The rechargeable, high capacity Lithium Polymer battery pack allows it to be recharged and redeployed, extending the product life.

Utilising the latest technology, the Sting can operate in ultra-low power modes. With an incredible battery life of up to 18 months on a charge, the Sting can be attached to assets and tracked without needing to charge the battery regularly. The Sting has built-in antennas for GPS reception and cellular 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 light sensor is designed to work as a tamper detector for cargo applications. If a parcel or container is opened, the Sting can detect the light change, wake up and report the tamper.

The temperature and humidity sensor allows spoilable cargo to be tracked.

The Sting is available in different versions to cater for different networks around the globe. Enquire with Digital Matter as to availability in your country.
The Sting uses a 2500mAh 3.7V Lithium Polymer battery pack. It can be recharged with the included USB micro cable.

    High sensitivity GPS

    UBLOX MAX-M8Q GPS module

    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 Sting 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

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

    SIM Card

    The Sting uses a micro-SIM card holder (3FF form factor)

    Cellular Communications

    The Sting can be manufactured for specific markets around the world depending on their modem requirements:

    2G Modem

    Quad Band GSM/GPRS Class 10
    850 / 900 / 1800 / 1900 MHz

    3G Modem – EU

    850 / 900 / 2100
    EMEA / APAC / Latin America

    LTE-CAT1, CATM and NB-IOT currently in development

    Enquire for other bands and LTE / 4G options


    In progress

    Internal Antennas

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

    3 axis accelerometer

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

    Future firmware versions will allow for harsh G-force detection (like assets being dropped or involved in accidents)

    Flash memory

    The Sting has enough flash to store over 25,000 data records, and will record information even when out of cellular coverage.

    The flash memory is also used to store firmware updates, GPS aiding data, parameters and other important information.

    A future firmware version will allow for geo-fences to be loaded into the flash memory of the device and used for geo-fence alerting on the device.

    The Sting is a stand-alone tracking unit and therefore does not have peripherals available.

    Firmware Smarts

    OTA Configuration

    The Sting can be remotely configured and updated OTA (over the air). Device management is performed from Digital Matter’s OEM Server device management platform.

    Recovery Mode

    The Sting can be remotely switched into Recovery Mode which switches the device to do live tracking and reporting – so that you can get your asset back!


    Auto-APN allows the Sting to analyse the SIM card and select the correct APN details from a list that is pre-loaded in the device’s firmware. This means that the Sting can be shipped world-wide without requiring specialist setup for SIMs.

    Text Message Setup

    The Sting can also be sent text messages to setup the APN, and other details

    AssistNow Offline

    The Sting 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.

    G-Force Events

    A future firmware version will allow for harsh G-force detection (like assets being dropped or involved in accidents) and report these to the server.


    The Sting has the capacity to hold hundreds of geo-fences that can be downloaded to it from the server and updated Over-The-Air.

    A future firmware version will allow the Sting to use this geo-fence information to implement geo-fence based alerting on the device.

    Device Management – OEM Server

    All Digital Matter devices are fully managed Over-The-Air (OTA) via our OEM Server web interface. The OEM Server seamlessly manages:

    • Device firmware – firmware updates can be done remotely
    • Network (administrator) parameters relating to critical communications
    • System parameters, including GPS parameters, IO configuration, logging options and general device behaviour settings
    • GPS AssistNow Offline aiding data files
    • Remote debugging of devices, including being able to trace data, view detailed debug message logs, and view a live trace of the server debug messages
    • Remote disconnect and reboot of devices
    • Driver list downloads to devices – this allows for the Driver Identification on the device to check if the RFID tag / username / PIN is valid, and for specific drivers to be allowed to drive / operate particular vehicles, for example based on licences or permits.
    • Geo-fence syncing with the devices – this allows the device to do advanced in-cab alerting and monitoring such as geo-fence arrival and departure, speed limit alerting, dangerous intersection warnings, turn on warning lights inside a geo-fence, and disable communications inside intrinsically safe zones such as gas plants.
    • Provides a command and message queueing platform to the devices and is incorporated into the remote management and debugging applications


    Data Connectors

    The OEM Server provides Data Connectors that forward data records on to the software platform of your choice, including Digital Matter’s own Telematics Guru and GPS Log Book platforms.

    More information on the OEM Server can be found at http://www.digitalmatter.com
