The AT-4 is a purpose-built 4G CAT 1 pet GPS tracker engineered for reliable, long-duration tracking of larger animals. As a Green-Gps compatible device, the AT-4 delivers accurate positioning, long standby life, and direct owner interaction via two-way calling and remote voice monitoring — making it a strong choice for owners, breeders, and handlers who need dependable real-time tracking in outdoor and open-range environments.
The AT-4 combines robust outdoor durability (IP67-rated ABS shell), a high-capacity 3000mAh rechargeable battery, and broad cellular coverage on 4G LTE-FDD and fallback GSM bands to keep location and status updates flowing to smartphone apps and platforms that accept standard GPS/GSM trackers. Its feature set — geofence alarms, low-battery alerts, history playback, searching light, and audible buzzer — integrates smoothly with Green-Gps’s platform for instant notifications, route review, and remote monitoring of pets in the field.

How It Works with Green-Gps
When paired with Green-Gps, the AT-4 streams position and status data over its cellular link to the platform so owners and operators can monitor animals in real time, receive alarms, and review telemetry history. Green-Gps ingests the device’s location and event messages to power live maps, geofence notifications, and history playback, making it straightforward to incorporate the AT-4 into workflows for pet safety and field management.
- Real-time location and telemetry updates delivered via 4G LTE-FDD to Green-Gps-compatible apps and dashboards.
- Two-way calling and remote voice monitor enable live audio contact and passive listening through the device.
- Geofence alarm support with immediate notifications when an animal leaves a defined area.
- Low-battery alerts and remote monitor functions to maintain oversight and reduce downtime.
- History playback for route review and behavior analysis over time.

Why Choose This Tracker with Green-Gps
Choosing the AT-4 as a Green-Gps compatible GPS tracker brings a balance of long battery life, rugged outdoor design, and owner-facing interaction tools that matter for animal tracking. Its 3000mAh battery and efficient 4G LTE-FDD connectivity reduce charging overhead and keep the device online for days or weeks, while IP67 protection and an ABS shell withstand real-world use. Two-way calling, remote voice monitor, geofence alarms, and searching light are practical features that enhance safety and make on-the-ground recovery and comfort easier.
For teams or individuals who also use Green-Gps for broader asset management, the platform supports a range of telemetry use cases. While the AT-4 focuses on pet tracking, Green-Gps-compatible solutions can support fleet management scenarios that include telemetry, anti-theft measures, and vehicle-specific features such as fuel monitoring, ignition control, and immobilizer functions when paired with devices designed for those purposes. That flexibility makes Green-Gps an effective hub for combining pet-focused trackers like the AT-4 with other telemetry-enabled devices and Bluetooth sensors in a single operational view.
