GPS trackers for vehicles and equipment

A GPS tracker is a basic sensor confirming an object’s presence in the physical world. In its minimal configuration, it shows location. In an extended configuration, it becomes a control tool: fuel monitoring, ignition control, door opening and locking, logging idle time, routes, and deviations. The same class of devices covers tasks ranging from “where is the vehicle now” to full telemetric fleet control.
The connection method defines capabilities, cost, and usage scenarios. In practice, three options are used: connection via the OBD2 diagnostic port, wired installation in a concealed location, and an autonomous GPS beacon. Let’s examine each in more detail.

GPS tracker with OBD2 connection

It connects directly to the vehicle’s diagnostic port (OBD2). Installation requires no technical expertise and takes only minutes, with no interference in the vehicle’s wiring.

Functionality:
  • online location monitoring;
  • speed, mileage, routes, geofences;
  • vehicle onboard data (RPM, fault codes, engine status, and other parameters — if supported by the vehicle);
  • driving behavior monitoring.
Limitations:
  • the device is physically accessible;
  • not suitable for all types of vehicles;
  • minimal integration capabilities with other control devices.
Typical use cases:

personal vehicles, leasing, temporary monitoring, rapid deployment without installation.

Solution cost:

The lowest in the range.

Wired GPS tracker (concealed installation)

Installed in a location that is not easily detectable. It connects to the vehicle’s power supply and control circuits, so it requires a certain level of technical skill and expertise. The wire length is up to two feet, which simplifies concealed installation.

Functionality:
  • online location monitoring;
  • speed, mileage, routes, geofences;
  • fuel consumption and fuel level monitoring (via CAN, sensors, or calculated);
  • starter, fuel pump or ignition control;
  • monitoring of door, hood, and trunk opening;
  • full integration with external sensors;
  • high resistance to tampering.
Limitations:
  • requires professional installation;
  • higher cost compared to OBD2.
Typical use cases:

Commercial vehicles, fleet management, specialized equipment, control and management tasks.

Solution cost:

Mid-range, depending on configuration and additional sensors.

Autonomous GPS beacon

A self‑powered device with its own built‑in battery. It does not connect to the vehicle’s onboard electrical system. Installed covertly, with no traces of installation.

Functionality:
  • scheduled or event‑based transmission of coordinates;
  • sleep/wake mode for energy saving;
  • asset tracking and recovery in case of theft;
  • backup monitoring channel in case the primary tracker is disabled.
Limitations:
  • no vehicle control;
  • limited data transmission frequency;
  • not intended for continuous real‑time tracking.
Typical use cases:

Anti‑theft solution, backup tracker, monitoring of high‑value assets.

Solution cost:

From mid‑range to high, determined by autonomy and battery life.

From a systemic perspective:

  • OBD2 — rapid deployment and minimal cost.
  • Wired solution — control and management.
  • Beacon — insurance against the worst-case scenario.

In practice, they are often combined. It’s cheaper than the cost of being blind to events.
