TagRanger® Applications


A TagRanger® system has four general modes of operation.  All of these modes are highly configurable and combine different elements of the feature set to give you optimum performance in your application.


Using the TagRanger® App with the Finder device, you can remotely request any TagRanger® Tag to report its GPS location on-demand.

This remote wake-up feature allows you to receive real-time GPS location updates from the Tags, providing crucial insights into the location and movement of animals. If it is not possible for the Tag to acquire a fresh GPS position it will report the last known GPS position.

The GPS position is displayed on the map in the TagRanger® App with a log of the time it was acquired.


Finding Tags (Ranging)

Sometimes it’s not enough to know where your Tag is, but to actually find it for a number of purposes such as:

  • Close observation of an animal
  • Animal intervention such as a veterinary procedure
  • Download of large datasets from Tag
  • Tag recovery for recharging or replacement
  • Wildlife filming

With TagRanger® you can find your Tag using a combination of LoRaWAN, GNSS and UWB Ranging technologies.  Once you have carried out a ‘Locate on Demand’ as described above, you can go to the GNSS location to start your search. If you are in range, the UWB ranging capability can then be used to give you a precise distance to the Tag, so even if you can’t see it, you can home-in until you are close enough to touch. This is also a good way of distinguishing between several Tags in close proximity (for example, turtles on a beach or deer in a herd).

This capability can also be utilised on equipment!  If you have a remote camera camouflaged at a location and a user unfamiliar with the hiding place was sent to service the camera (replace batteries, retrieve memory card), they could use the ranging capability to discover the camera quickly, even in the dark.


Animal Tracking

Traditional animal tracking can be carried out using TagRanger® which can track the location of your Tags. GPS locations are updated automatically according to your own preset schedule and stored on the Tag.

You can choose whether to transmit each location as it is acquired (live tracking) or download them at a later date.


Data Logging

All data from the GNSS, temperature sensor and accelerometer is logged on the Tag for download when you choose. A total capacity of up to 2MB ensures there is plenty of storage for extensive data sets.

The data can be downloaded using the UWB radio interface when you are within 25m of the Tag or using the Bluetooth connection if you have recovered the Tag.
