Get in Touch Remora2

Battery Powered, 4G Cat-M1/Nb-IoT GPS tracker with BLE


The next generation Remora is here - supercharged and more powerful than ever.

The Remora2 is an IP67 rated, rugged 4G Cat-M1/Nb-IoT GPS device designed for tracking non-powered assets where super-long battery life is required without sacrificing the frequency of updates and accuracy performance.

Convenient mounting holes make it easy to mount the Remora in the corrugation for container tracking, or conceal on the underside of a trailer.

The Remora2 is powered by 2 x D Cell Lithium Thionyl Chloride (LTC) batteries for super long battery life. LTC batteries also offer continued operation in extreme temperatures.

The Remora 2 is PACKED with technology and features to provide superior tracking performance.
  • Up to 10 years of battery life at once daily GPS location and 5 years once hourly
  • IP67 Rugged weather-proof housing
  • BLE v5
  • Battery Meter
  • Magnetic Tamper detect
  • Easy installation

4G Cat-M1/Nb-IoT Modem

The Remora 2's 4G modem is compatible with both Cat-M1 and Nb-IoT networks - enabling great new benefits. Traditional cellular network specifications (like 4G LTE Cat 9/12) are designed to provide high speeds and bandwith - to enable smartphone users to stream videos and facilitate other data-intensive activities.

IoT devices don't need this type of bandwidth and are typically trying to solve other problems. These IoT devices require
  • Small data messages typically at low data rates
  • Long Range
  • Low power to allow for long battery life
  • Low cost - to facilitate the deployment of many millions of them
The LTE Cat-M1 and NB1 specifications allow the cellular modem (uBlox SARA R4) to be simpler and smaller. In our testing we have measured that our new Cat-M1 devices use anywhere from 1/2 to 1/3 of the power of our 3G devices to perform a data upload. The combination of this technology and the LTC Batteries yields SUPER-LONG battery life. Up to 90 000 uploads, or 10 years once hourly updates!

LTC Batteries

The Remora 2 is powered by Lithium Thionyl Chloride (LTC) batteries. These batteries help achieve the optimum performance due to the following reasons:
  • Higher quality out of the box, meaning less chance of early failures compared to Alkalines
  • Extended temperature tolerance, operating temperatures of -40°C to +85°C are typical
  • High Capacity - meaning many years of operation
  • Extremely low self discharge - typically around 1%

Battery Meter

The Remora 2 is fitted with a Coulomb Counter which tracks the devices energy consumption. It is hard to predict the battery life of LTC batteries due to their flat discharge curve, so the Battery Meter enables an accurate battery level to be determined, enabling the following:
  • Accurate Low Battery Alerts - Alerts can be set at any level which provides enough time for new batteries to be fitted.
  • Battery Life Predictions - The Remora 2 can simply be deployed in the application with the desired settings for a short time (a week or so). The energy usage over this time can be determined, and from there battery life can predicted accurately - no more guesswork!

Bluetooth Gateway

The Remora 2 is equipped with a Bluetooth v5 module, enabling it to act as a Bluetooth Gateway. Low-cost Bluetooth tags can be fitted to low value assets. This opens up many low-cost tracking solutions.

For example a business with 2 work sites could place a Remora 2 at each, and Bluetooth tags on their pallets/stock/tools. The site the assets are located can be determined by which Remora the Bluetooth tags report to.

Tamper Detect

The Remora 2 housing is built with a recess on it's underside. This enables a magnet to be attached to the asset, and the Remora 2 place over this magnet. When the Remora 2 is removed from the asset - the change in magnetic field is detected and an alert is sent to the server. Giving you peace of mind that your asset is protected.

    Low Noise GPS Amplifier (LNA)

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


    Bluetooth v5

    The Remora 2 is equipped with a Bluetooth v5 module, enabling it to communicate with Bluetooth tags.
    Such tags can be placed on low-value assets to provide their position when in range of the Remora 2.

    Internal Memory

    Sufficient memory to store over 50,000 records. Normally data is sent to the server immediately but if the device is out of range there is space to ensure no data is lost.

    3-axis accelerometer

    The 3-axis accelerometer allows the Remora 2 to ‘sleep’ in an ultra-low power state yet still wakeup when movement occurs.
    The accelerometer can also be used to detect extreme G-Force events such as an accident or abuse of the asset, for example dropping a container

    Magnetic Tamper Detect

    Optional magnetic wireless tamper switch detects when the device has been removed from the asset.

    Battery Meter

    A coulomb counter acts as a ‘battery meter’, tracking the energy consumption of the Remora 2. This enables an accurate battery percentage to be reported.
    The battery meter also allows accurate battery life predictions. Simply deploy the Remora 2 in your application with the desired settings. The energy usage will be reported, enabling you to extrapolate to determine the battery life time.

    OTA Configuration

    The Remora 2 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 Remora 2 can be remotely switched into Recovery Mode which switches the device to live tracking and reporting – so that you can get your asset back!

    G-Force Events

    The Remora 2 can detect harsh G-force events (like assets being dropped or involved in accidents) and report these to the server.


    The Remora 2 has the capacity to hold hundreds of geo-fences that can be downloaded to it from the server and updated Over-The-Air. This allows the Remora 2 to use this geo-fence information to implement geo-fence based alerting on the device, or use alternate logging parameters when inside a geo-fence.

    Adaptive Tracking

    The Remora 2 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.

    Performance Monitoring

    Track how the Remora 2 is using its power with intelligent performance counters. Monitor wakeups, GPS fixes, uploads and more to understand exactly what the device is doing.

    AES-256 Security

    The Remora 2 uses bank-level AES-256 device authentication and data encryption to ensure that your data is kept private and secure

    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 platform.
