GPS Fleet Tracker

Overview

SGT GPS Fleet Tracker is a hard-wired or plug-and-play vehicle telematics unit — live GPS, speed, route history, geofence alerts, driver scorecard, fuel and ignition monitoring — streaming over 4G/LTE to a unified fleet dashboard.

Built for delivery fleets, taxi and ride-hail, logistics, school transport, and rental businesses across Bangladesh, India and South-East Asia. Installations take 20-40 minutes; fleet managers get a live map, trip history, exception alerts and a per-driver scorecard.

Live GPS + route history — 5-30 s sampling, 90-day default retention
Geofence alerts — entry, exit, dwell, after-hours, route-deviation
Driver scorecard — speeding, harsh brake, harsh corner, idle time, fuel economy
Tamper detection — power-cut, antenna-cut, vibration, ignition-without-driver alerts

How It Works

Install — hard-wired to ignition, battery and ground (20-40 min) or plug into OBD-II port (5 min). Optional CAN-bus tap for engine data.
Track — GPS fix at 1 Hz; position, speed, heading, RPM and fuel are buffered locally.
Stream — packets are sent over 4G/LTE every 10-30 s when moving, 5 min when idle; data is buffered offline for hours.
Alert — geofence, over-speed, harsh-event, tamper and SOS alerts are pushed to dispatcher and driver app in seconds.

Features

Live map & replay — break-by-break trail with stops, idle and harsh events marked
Geofencing — unlimited circular / polygon zones, entry / exit / dwell rules
Driver scorecard — 0-100 score, ranked leaderboard, weekly PDF report
Trip log — start / end address, distance, duration, fuel, idling, max speed
Engine & CAN — RPM, coolant temp, fuel level, MIL light, DTC codes (optional)
Fuel monitoring — derived from CAN or paired tank-level sensor; theft alerts
Tamper & SOS — power cut, vibration, panic button, driver-ID iButton optional
Open API — REST + webhook for ERP / TMS / dispatch integration

Use Cases

Last-mile delivery — proof of delivery, ETA, route optimization
Taxi / ride-hail — meter-correlated trip log, driver scorecard, customer safety
School transport — geofence around schools, parent ETA notifications
Logistics & long-haul — pan-region tracking, driver hours, rest stops
Construction / heavy equipment — engine hours, idle time, unauthorized use
Rental & leasing — over-speed alerts, geofence violations, recovery on theft
