G5-D Iridium/GPS Collar, 500 g

 A dependable, field proven GPS collar utilizing the most capable satellite communication technology available: Iridium. Plus, unlimited text messaging on mortality and geo-fencing events.


  • A nominal monthly subscription fee, as well as a per-location fee, is invoiced to you on an monthly basis.
  • Typical life: 4 years @ 6 locations/day, data uplinked once every 2 days, VHF on 8 hours/day
  • 100% wireless operation provides greater reliability.
  • On-board Iridium transceiver provides 2-way communication capability for on-the-fly programming changes

Get your animal's data from anywhere you can access the internet.

The model G5-D uses the Iridium satellite to transmit GPS location data collected by the collar. An integrated VHF transmitter allows you to track the animal in the field. Neolink neonate monitoring  and geo-fencing are both available at a nominal cost.

Your collar's GPS location data is uploaded to ATS' managed Iridium website (atsidaq.com) according to the schedule you choose. A Google Earth data file is included. SMS Text messages can be programmed to be sent on mortality and geo-fencing events.

The G5-D collar is programmed wirelessly using the Wildlink Comm. Module and Windows-based software running on your PC. You can control how often fixes are collected and stored, how often data is uploaded to the ATS Iridium website (up to six uploads per day, each holding 22 locations), and how often the VHF beacon will transmit (this allows you to maximize battery life).

You can also remotely command program changes to the fix rate and mortality schedule, fix duration time, and Iridium data transmission interval, using the website.
