The Arribada Horizon ARTIC R2 Developer's Kit was developed by Arribada to unlock access to open source Argos telemetry. The kit includes an Arribada Horizon GPS biologger and our new pre-certified Argos ARTIC R2 transmitter. Using the Python command line tool and supporting documentation, you can get up and running quickly and easily. The aim of the product is to deliver a plug-and-play solution for engineers, students and developers wishing to integrate Argos telemetry into their own solutions, or to modify the hardware to create custom devices as both the hardware and software is open source. Co-developed together with the Zoological Society of London, the same kit was used by the National Geographic Society to track plastic waste leaving the Gange's delta as part of their Sea to Source Expedition.
