Accessories for ARGOS Horizon GPS Dev Board

Founding developers Alasdair Davies, Robin Freeman and Rachael Kemp

The device was developed by the Arribada Initiative and the Zoological Society of London to unlock access to low-cost open source bio-logging technology, where Alasdair Davies was the main coordinator with the goal to design, develop and produce open hardware to be used in animal conservation as part of his Shuttleworth Foundation Fellowship.

Horizon is an open source plug-and-play solution to develop or deploy your own satellite telemetry solution.


The ARGOS Horizon GPS Dev Board includes GPS, Bluetooth 5.0, a 9-axis accelerometer and supports an external 3G cellular board (also open source). It is a GPS logger and an ARGOS satellite communication control board, suitable for tracking wildlife, environmental assets or embedded into custom devices (UAVs, buoys, marine equipment). It is programmable over USB or bluetooth using a free Python command line tool to configure GPS and ARGOS transmitter settings.

The Dev Board connects easily to the ARGOS Horizon Module (containing the ARGOS ARTIC R2 satellite transmitter). Using the picoblade cable gets you up and running quickly. It is compatible with the next generation ARGOS-4 satellites and the future KINEIS constellation of nanosatellites.

Power should come from a 3.7V lithium-ion or lithium polymer battery with a standard JST header (NOT included). 

Developer friendly

You can easily configure and modify settings over USB using straight forward Python tools, or use the built-in Bluetooth 5.0 to communicate with the tag wirelessly.
