What Does the GPS Tracking Device Track? GPS Tracking Data and Features

The GPS tracking device tracks a vehicle's position, what the engine reports, and how the vehicle moves, drawing its GPS tracking data from three sources in one box. A GNSS receiver gives position, speed and heading. An accelerometer measures motion, such as braking, acceleration, cornering and impacts, independent of the engine. The connection to the vehicle's onboard diagnostics passes on what the vehicle itself knows: engine on and off, RPM, odometer, fuel, fault codes, and hundreds of other parameters depending on the make. Nearly everything a fleet uses comes from one of these sources, or from a rule that combines them.

Here are the core data points and the job each one does.

The GPS tracking device has no microphone and no camera, so it records no audio, no video and nothing said in the cab. Video comes only from a separate camera connected through the IOX port, and the fleet configures that camera's recording rules. The device doesn't read the driver's phone, and it doesn't track a person who is out of the vehicle. During personal conveyance, the ELD record stores location at reduced precision, although the fleet's own map still shows the vehicle.

The device also knows only what the vehicle tells it. Fuel level, seat belt status and some engine parameters depend on the make and model exposing them, and an older or unusual vehicle may report fewer of them. Check the specific vehicle before you promise anyone a specific report.

The device doesn't log at a fixed interval. It records a point whenever the vehicle's motion changes enough that a straight line between points would misrepresent the path. This curve-based logging keeps the trip shape accurate on corners without filling the record with identical highway points. Position accuracy depends on the receiver: typically within a few metres under open sky, and worse in dense urban canyons or under cover. Data reaches the platform over cellular in near real time. When there is no signal, the device buffers it and sends it once coverage returns.

Two fleets with the same devices can get very different value from them, depending on which data they act on. Position alone tells you where a vehicle is. Engine hours and fault codes tell you when it is likely to break down, idle time shows where the fuel is going, and accelerometer events point to the drivers who need coaching. The device records all of it from the day it is installed, so a fleet that starts with the map and never opens the rest uses a fraction of what it paid for.

The device records dozens of parameters, and a fleet acts on a handful. These drive most reports and rules, each with the decision it supports.
