The AT-23 2G Relay GPS Tracker from a compact vehicle terminal family delivers reliable Green-Gps compatible real-time tracking and a built-in relay for remote fuel or power cutoff. Designed for permanent installation inside cars, trucks, motorcycles, boats and other mobile assets, the AT-23 combines precise GNSS positioning (GPS + Beidou) with vehicle-grade power management to support anti-theft immobilizer workflows and fleet management telemetry.
As a Green-Gps compatible device, the AT-23 feeds live location, telemetry and event data into Green-Gps dashboards for geofencing, history playback and automated alerts. Its small form factor and modular wiring make installation straightforward, while the relay-based cutoff and resume function delivers a practical immobilizer option for fleet operators, vehicle owners and asset managers who require fast, enforceable anti-theft measures.
Key Highlights
- Green-Gps compatible GPS tracker providing real-time tracking and route history for fleet management and asset monitoring.
- Integrated relay for remote fuel or power cutoff and resume—effective anti-theft and immobilizer capability.
- Dual-mode GNSS positioning (GPS + Beidou) with typical position accuracy <10 m (1σ).
- Low-power operation: DC 9–35V input, average ~40 mA at 12V, and sleep current <10 mA; optional 80 mAh backup battery for short-term power loss operation.
- Event alerts including geofence entry/exit, overspeed warnings, vibration detection, low battery and main power cut-off notifications.
- Small, discreet ABS housing (32.5 × 32.5 × 31 mm) for concealed vehicle installation.
- Supports standard SIM card on 2G (850/900/1800/1900 MHz) networks and internal antennas for cellular and GNSS reception.
How It Works with Green-Gps
The AT-23 transmits location, status and event messages over 2G to Green-Gps-compatible servers so operators get real-time visibility and historical telemetry inside Green-Gps dashboards. Integration is straightforward for platforms that accept standard 2G trackers: the device reports position and a rich set of alerts that Green-Gps can use to trigger notifications, create reports and automate fleet workflows.
- Real-time location and telemetry updates sent to Green-Gps for live mapping and route playback.
- Geofence entry/exit alerts and overspeed warnings appear in Green-Gps alongside location history for fast investigation.
- Relay status and remote immobilizer control: Green-Gps can display relay state and record cut/resume events (remote action performed via authorized backend workflows).
- Power and battery events: main power cut-off alerts and low backup battery notifications help operators detect tampering or power loss.
- Vibration and movement detection for tamper/parking alarms—events are logged and shown in Green-Gps incident timelines.
- Coexistence with Bluetooth sensors and other peripherals in the same Green-Gps deployment—while the AT-23 itself uses internal antennas and 2G, Green-Gps can correlate its telemetry with BLE sensor feeds from other gateways if used in the same system.
