The AT09-4G is a rugged 4G GPS tracker built for demanding vehicle environments — cars, trucks, trailers, mining machines and more. Designed to be ALTAGAMA GPS compatible, the AT09-4G provides reliable real-time tracking and rich telemetry over LTE networks, combining multi-constellation GNSS positioning (GPS/GLONASS/Galileo/BDS) with advanced vehicle-condition sensing for fleet management, anti-theft and operational visibility.
With extensive I/O, LoRa and Bluetooth connectivity, TPMS and multi-channel fuel monitoring, the AT09-4G gives fleet and asset managers a single device that streamlines location, safety and vehicle data into platforms such as ALTAGAMA GPS. The unit supports voice, optional video, a 4G Wi‑Fi hotspot and flexible reporting triggers — ideal for operations that demand accurate location plus deep telemetry for maintenance, security and compliance.
Key Highlights
- ALTAGAMA GPS compatible GPS tracker offering real-time tracking and multi-constellation GNSS (GPS/GLONASS/Galileo/BDS) for reliable positioning.
- Advanced telemetry: online TPMS (up to 42 sensors), multi-channel fuel monitoring (up to 4 analog sensors), temperature and sensor voltage reporting.
- Comprehensive I/O and peripheral support — RS232 (2), RS485 (1), CAN (1), TTL (1), 1-wire (2), digital inputs/outputs and analog inputs for rich vehicle integrations.
- 4G LTE connectivity with SMS, TCP/UDP GPRS and ability to send data to two servers simultaneously; ideal for fleet management and redundancy.
- LoRa and Bluetooth support for IoT connectivity; can operate as LoRa gateway or node and connect Bluetooth sensors/beacons for local monitoring.
- Built-in microphone and speaker for two-way voice, USB for OTA firmware updates, and optional video and Wi‑Fi hotspot for passenger or driver connectivity.
- Robust safety and alarm suite — geofencing, overspeed, tamper, towing, SOS and harsh-driving notifications for anti-theft and driver-safety workflows.
How It Works with ALTAGAMA GPS
When integrated with ALTAGAMA GPS, the AT09-4G delivers continuous location and telemetry streams, giving dispatchers and managers live situational awareness. Device data is transmitted over LTE or GPRS to ALTAGAMA GPS using standard TCP/UDP or SMS fallback; configurable triggers control reporting frequency so you balance data usage with precision. ALTAGAMA GPS receives GNSS coordinates, TPMS and fuel sensor readings, alarm events and digital I/O states, enabling real-time tracking, alerts and historical reports.
- Real-time location and telemetry updates: GNSS position, speed, heading and multi-constellation fixes.
- Ignition and engine status: engine on/off detection and digital inputs for ignition events to support fuel and driver-session analytics.
- Fuel monitoring: simultaneous support for up to four analog fuel sensors, including Omnicomm and ultrasonic sensors for accurate fuel monitoring.
- Remote immobilizer support via optional relay or OBD peripherals — enables immobilizer workflows when configured in ALTAGAMA GPS.
- Bluetooth sensors and LoRa IoT: connect BLE sensors or use LoRa gateway/node modes to ingest temperature, cargo sensors or beacons into ALTAGAMA GPS.
- TPMS telemetry: live tire pressure, temperature and sensor voltage for tire-health alerts and predictive maintenance.

Why Choose This Tracker with ALTAGAMA GPS
The AT09-4G is a practical choice for organizations that require a ALTAGAMA GPS compatible GPS tracker with comprehensive telemetry and flexible integrations. Its wide voltage range, backup battery and rugged form factor make it reliable for commercial and industrial vehicles. Extensive I/O and support for peripherals (relays, OBD modules, iButton/RFID, cameras) allow you to implement immobilizer workflows, driver identification and custom alarms without replacing core hardware. The built-in TPMS and multi-channel fuel monitoring reduce maintenance risk and enable fuel monitoring insights, while LoRa and Bluetooth sensors let you extend telemetry to cargo and environmental sensors. Paired with ALTAGAMA GPS, the AT09-4G delivers actionable, real-time tracking and fleet management data that improves security, lowers operational costs and simplifies vehicle telemetry across mixed fleets.
