ARC 400 Tag

We can help you find your animal . . . but what was happening to it in the meantime?


Research relating to thermal ecology, foraging ecology, energetic requirements from movement data, etc. can be accomplished using ARChive tags. With ARChive transmitters, you are no longer limited to manually tracking, observing, and recording data in the field. You can continuously and automatically collect important habitat and behavioral data over the course of months, or even years.

The tags are pre-programmed by ATS. They work like a VHF tag does, but with added on-board sensors which measure and data log temperature and/or activity information. To collect data, you retrieve the tag and send back to ATS to download and supply your data. ATS can program the VHF beacon to transmit at predefined intervals, so battery life is conserved, offering long-lived operation.

Units will be pre-programmed prior to shipment and downloaded by ATS when study is complete or once the battery expires.
