The AT07-4G (also referenced as AT07-3G/4G) is a compact, rugged GPS tracker engineered for demanding vehicle and asset deployments. Designed for reliable fleet management and anti-theft protection, the AT07-4G delivers Plaspy compatible real-time tracking, robust telemetry and flexible peripheral integration for fuel monitoring, door/ignition status, and emergency alerts.
Built to operate across multiple cellular variants and GNSS constellations, the AT07-4G combines persistent connectivity, onboard logging and OTA firmware upgrades to keep vehicles and assets visible under network loss or harsh conditions. Its compact form factor and wide power input range make it ideal for mixed fleets that require accurate position, diagnostics and event-driven reporting into Plaspy.
Key Highlights
- Plaspy compatible GPS tracker with real-time tracking and historical trace logging for fleet management and asset visibility.
- Multi-constellation GNSS (GPS/GLONASS/BeiDou) using a 50-channel AT6558R chip for fast reacquisition and tight position accuracy.
- 3G/4G cellular variants and quad-band GSM with configurable GPRS reporting by time, distance or course change.
- Rich I/O for telemetry and peripherals: RS232 port for external sensors (Omnicomm fuel meters, RFID), 1-wire temperature input, digital/analog I/O and voice ports.
- Onboard 16MB flash memory stores ~4,000 records when the network is unavailable; OTA firmware upgrades and SMS/GPRS configuration supported.
- Comprehensive alarm set: geo-fencing, overspeed, SOS, door status, external power lost, towing, idle and vibration (tremble) detection.
- Wide power tolerance and protection with DC input options, built-in over-voltage protection and an 800 mAh high-temperature Li-Polymer backup battery.
How It Works with Plaspy
When paired with Plaspy, the AT07-4G supplies continuous location and telemetry into your tracking platform. The device supports configurable reporting modes and can stream position and event data to up to two servers simultaneously. Plaspy ingests GPS/GLONASS/BeiDou fixes, I/O events and sensor telemetry to provide live maps, alerts and analytics for fleet managers.
- Real-time location and telemetry updates (GNSS fixes, speed, heading).
- Door, SOS, external power lost and other digital event statuses for anti-theft and security alerts.
- Fuel monitoring via RS232-connected fuel sensors (Omnicomm compatibility) and analog inputs for fuel-related telemetry.
- Remote immobilizer control via external relay (optional peripheral) and digital outputs where deployed in immobilization workflows.
- Temperature and auxiliary sensor data via 1-wire port and serial/analog interfaces, enabling environmental monitoring and asset condition tracking.
