📡 Overview

VLTD Overview

The VLTD is an AIS-140 compliant vehicle location tracking device built on a 32-bit embedded controller. It combines 4G LTE Cat 1 cellular connectivity (with 2G fallback), L1/L5 dual-band multi-constellation GNSS with NavIC/IRNSS support, dual-profile eSIM, and BLE 5.4 — all in a compact IP67-rated ABS enclosure.

Designed for 9–90V DC vehicle systems, the unit includes on-device history storage with ≥40,000 records, configurable digital and analog I/O for ignition, SOS, door, and A/C monitoring, and relay outputs for engine immobilisation. An on-board IMU (3-axis accelerometer + gyroscope) enables harsh driving event detection.

“A complete, Made-in-India edge computing platform for vehicle telemetry — engineered by Nevon AI for public transport operators, commercial fleet owners, and regulatory compliance.”
