Telonics Terrestrial GPS/Iridium Satellite Tracking Collars

Advanced Two-Way Satellite Telemetry and Space-Grade Hermetic Sealing Technology for Precision Monitoring, Functional Management, and Comprehensive Wildlife Conservation in Global Terrestrial Environments

Optimize your research, ecology, and conservation projects with the Telonics series of terrestrial GPS/Iridium collars. Specifically designed to withstand the most rigorous field challenges and the demands of modern biology, these devices allow you to collect high-precision geographical positions and transmit them in real time from any corner of the planet via the Iridium network's constellation of 66 low Earth orbit (LEO) satellites.

Thanks to their two-way communication architecture, you not only receive mortality alerts, climate data, and activity logs on your screen, but you can also send remote commands to reprogram sampling intervals or activate release mechanisms without the need to recapture the animal. Furthermore, models from the TGW-4270-5 series onward incorporate a space-grade hermetic sealing inside a metal housing—the same technology used by NASA—completely eliminating moisture penetration and guaranteeing the long-term operational success of your scientific campaigns.

Key Features

• Integrated Iridium satellite network featuring sixty-six low Earth orbit satellites for continuous, 24-hour global coverage.
• Advanced two-way communication enabling message acknowledgement and remote modification of programmed parameters.
• Quick Fix Positioning technology that acquires positioning data in just two seconds, drastically reducing power consumption.
• Absolute hermetic sealing in a metal housing under NASA standards to prevent any water or moisture leakage under extreme conditions.
• Flexible programming of primary schedules and up to three interchangeable auxiliary configurations that can be switched remotely depending on the season.
• Integrated mortality sensor with automated accelerometer-based alerts, configurable for immediate email notification.
