About HYJN03 GPS Tracker

The Kaptan GPS HYJN03 is one of the most widely deployed slim-profile vehicle GPS trackers globally. It is a wired telematics device featuring internal high-gain antennas, Bluetooth 4.0 LE, an internal backup battery, and multiple I/O ports for vehicle integration.

Whether you are securing a personal car or managing a commercial fleet, the device provides the industrial-grade precision and ease of use you need. Monitor your fleet in real-time with our dedicated Android & iOS app. Manage your vehicles on-the-go with seamless tracking across India.

Key Features & Telematics Scenarios

• Remote Vehicle Immobilization — Control the Digital Output via SMS, GPRS command, or server trigger to shut down the starter relay or fuel pump during a theft attempt.
• Accident & Crash Detection — Built-in 3-axis accelerometer logs high-frequency trace data right before and after impact to assist with collision analysis and emergency alerts.
• Driver Behavior Analysis (Eco-Driving) — Monitors real-time driving habits, flagging events like harsh braking, harsh acceleration, and sharp cornering.
• Security & Anti-Theft Scenarios — Towing detection (vehicle moves while the ignition is OFF), GSM jamming detection, auto/manual geofencing with enter/exit alerts, and unplug/power disconnect alerts.
• Advanced Power Management — Configurable GPS Sleep, Online Deep Sleep, Deep Sleep, and Ultra Deep Sleep modes draw as little as <2 mA @ 12V.
• Configuration & Maintenance — Configurable over-the-air via FOTA Web, SMS commands, USB connection, or wirelessly via the FMBT Mobile App.

Core Hardware & Connectivity

• GNSS (Location) — 33-channel receiver with -165 dBm sensitivity supporting GPS, GLONASS, GALILEO, BEIDOU, SBAS, QZSS, DGPS, and AGPS.
• Cellular Network — Quad-band 2G GSM/GPRS (850 / 900 / 1800 / 1900 MHz) with multi-slot Class 12 data support.
• Bluetooth 4.0 + LE — Wirelessly integrates with external BLE sensors (e.g., Kaptan GPS EYE Sensors for temperature/humidity, magnetic door sensors, and driver ID beacons) or OBDII dongles.
• 1 Digital Input (DIN) — Used for ignition state monitoring, door status, or an SOS panic button.
• 1 Digital Output (DOUT) — Used for remote engine immobilization (relay control).
• 1 Analog Input (AIN) — Enables analog sensor monitoring (e.g., fuel level or external voltage monitoring).
• Internal Memory — 128 MB internal flash storing up to ~8,000 to 400,000 offline records when the cellular connection drops.
• Power Supply — 6 V to 30 V DC wide input voltage with overvoltage protection.
• Internal Backup Battery — 170 mAh Li-Ion battery (0.63 Wh) to send alerts if power is cut.

Primary Applications

• Commercial Fleets — Light commercial vehicles, courier vans, and taxi fleets.
• Car Rental & Leasing — Vehicle tracking and stolen vehicle recovery.
• Usage-Based Insurance (UBI) — Monitoring driver habits to calculate insurance risk.
• Motorcycles & Light Transportation — Ultra-thin profile (12 mm) allows covert installation under small panels or seat frames.

HYJN03 vs Other GPS Trackers

HYJN03 stands out as one of the most widely deployed slim-profile trackers globally. Its 12 mm ultra-thin form factor allows covert installation under small panels or seat frames, while internal high-gain antennas, multiple I/O ports (DIN, DOUT, AIN), and Bluetooth LE support bring industrial telematics capability into a compact package.
