The C2  is a low-profile, rugged 2G or 3G/4G LTE GPS device designed for tracking non-powered assets where super-long battery life is required without sacrificing the frequency of updates and accuracy performance.

The C-2 is able to roam onto cellular networks across the globe giving you global coverage of your assets movements at a low SIM card data cost. Communications with the device are two-way, allowing the C-2 behaviour and update rates to be changed Over-The-Air (OTA) including being able to be switched into “Recovery Mode”.

By utilising the latest technology the C-2 is able to operate in ultra-low power modes. With an incredible battery life of up to 5 years the C-2  can be attached to assets and tracked without needing to change batteries.

The option of using extended temperature range batteries allows the C-2 to be used in extreme climates that other tracking devices simply cannot operate in.

Optional magnetic tamper detection allows you to be notified should the device be removed from the asset, giving you peace of mind that your assets are protected. Convenient mounting holes and strap slots make it easy to mount the C-2 in the corrugation for containers tracking, or conceal on the underside of a trailer.

  • Compact, low-profile is easy to mount
  • No install required, simply “place ‘n trace”
  • IP67 Rugged weather proof housing
  • Powered by consumer batteries
  • Up to 5 years tracking (once daily)
  • Configure over-the-air (OTA)

Product Description



Low-profile IP67 rugged housing

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

Dimensions: 225 mm x 65 mm x 30 mm (excl. mounting tabs)
Weight: 500 grams with batteries


C size:
The C-2 uses 4 x “C” size batteries, which provide a perfect balance between size and capacity. Low cost off-the-shelf alkaline batteries can be used in the C-2.

For applications that require extreme temperature or extra long-life, Lithium-Thionyl-Chloride (LTC) batteries can be used.

Sleep Current:
5µA (micro amps),

Battery Life with Adaptive-Tracking

The C-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.

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

Operating Temperature

-20°C to +60°C

For operation in extreme temperatures, the C-2 must be fitted with LTC (Lithium Thionyl Chloride) 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 C-2 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 C-2 to operate where normal units will fail to receive GPS signal – like in a container stack!

Cellular Communications

The C-2 can be manufactured for specific markets around the world with cellular modem modules approved by all the major networks, and can roam across networks

Internal Antennae

Internal GPS and cellular antennae tuned by the RF laboratories to ensure optimal performance.

3 axis accelerometer

The 3 axis accelerometer allows the C-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

Flash Memory

The C-2  has sufficient memory to store over 50,000 records in its flash memory. Normally the data will be sent to the server immediately but if the device is out of range then there is sufficient space to ensure that no data is lost – for many months!

The flash memory is also used to store parameters, GPS aiding data, geo-fences and other important information that needs to be securely stored.


OTA Configuration

The C-2 emotely configured and updated OTA (over the air). Device management is performed from Ufind’s  OEM Server device management platform.

Recovery Mode

The C-2 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 C-2 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 C-2  can be shipped world-wide without requiring specialist setup for SIMs.

Text Message Setup

The C-2 can also be sent text messages to setup the APN, and other details.

Multi-APN for Roaming

The C-2 is configured to roam across multiple networks and to automatically use the different APN details for the roaming networks.

AssistNow Offline

The C-2  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.

All Ufind 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.
