Choosing a GPS tracker: Teltonika vs GT06 vs OBD — a practical comparison

Start from the need, not the device

The most common mistake when equipping a fleet is starting from a device catalogue instead of a simple question: what decisions do I want to make with this data? The answer selects the device class before any spec-sheet comparison.

If you need vehicle positions, status, trips and speeds, any reliable unit with a good GNSS receiver will do, and the differences between devices come down to build quality and connection stability. If you want fuel monitoring with drain detection, multi-zone temperature readings from refrigerated boxes, driver identification via iButton or RFID, or remote engine cut-off, you need a device with enough inputs and outputs for every sensor. And if your operation requires live video from vehicle cameras, that is a third class altogether, built on the JT/T 1078 standard.

Write the data list first — position? fuel? temperature? doors? weight? video? driver ID? — then compare the classes below against it.

And remember that a single fleet rarely needs a single class. A typical distribution company might equip its refrigerated trucks with advanced units carrying temperature and fuel sensors, and its sales reps' cars with budget or OBD devices. Standardising on one class fleet-wide "for simplicity" usually means overpaying on half the vehicles and under-equipping the other half; a single platform that manages every class on one screen resolves that equation without any added operational complexity.

Three practical classes

Class one: advanced wired units. The best-known example is Teltonika, alongside families such as Queclink, Ruptela and Galileosky. They are hardwired to the vehicle's electrics and stand out for their rich I/O: digital and analogue inputs for sensors, CAN bus reading on many models, and ports for accessories such as driver-ID readers and external fuel sensors. This class is the logical choice for trucks, heavy equipment and commercial vehicles that need more than location.

Class two: budget units. Headlined by the GT06/Concox family, together with devices like H02, GPS103 and Seeworld. Installation is simple wiring, and they cover the basics well: position, speed, ignition state, and usually a relay output for engine cut. Sensor inputs are limited, and fuel measurement through them does not match class one. But when equipping a large number of vehicles for basic tracking, they are a rational choice that visibly lowers the equipment cost.

Class three: OBD trackers. These plug straight into the OBD-II port found in most modern light vehicles — no technician, no wiring: installed in seconds and easily moved between vehicles. They read some data from the vehicle's computer in addition to position. The trade-offs are equally clear: being easy to remove makes them unsuitable where tampering is a concern, they have no inputs for external sensors, and in practice they suit light vehicles, staff cars and short-term rentals — not working trucks.

A fourth case sits outside this comparison: battery-powered trackers for unpowered assets such as trailers and containers, which come with entirely different trade-offs in battery life and reporting frequency — worth a guide of their own.

Head-to-head comparison

Note that the decisive rows are not cost but inputs and tamper resistance: a budget unit on a truck whose fuel is being stolen costs you several times the price difference every month.

Beyond location: fuel, CAN and sensors

Fuel monitoring is the requirement that raises the device bar most sharply. Raw fuel-sensor readings arrive noisy because the liquid moves, so the platform must apply per-tank calibration tables and smoothing, then detect fill and drain events by volume, time and location, raising an immediate alert on theft-like patterns. That chain works best with a calibrated sensor on a class-one device — see the fuel page for drain detection and actual-versus-standard consumption.

The same logic applies to specialised sensors: multi-zone reefer temperatures, load weight, PTO state on equipment, passenger counts, doors. Pixa's sensor abstraction layer lets you define any raw parameter the device sends with a name, a formula and a calibration table, plus a raw-data viewer for diagnostics — but no software layer can compensate for an input that does not exist in the hardware. A device without an analogue input will never read a weight sensor, however capable the platform.

If your plans include video — live streaming from cameras, pulling clips from device storage after incidents — look from the start for devices built on JT808 with the JT/T 1078 extension: a distinct class combining tracking and video, working with a media server that streams HLS/WebRTC as described in video solutions.

Two accessories sometimes settle the class decision before anything else: a driver-ID reader (iButton, RFID or BLE) if your vehicles rotate between drivers and you want penalty points recorded against the driver rather than the vehicle, and a control output for remote engine cut-off if your operation requires it — both are, in practice, advanced-class territory.

Platform compatibility: protocol first

The most important paragraph in this guide: before buying any device — or keeping units inherited from a previous provider — confirm your platform supports its protocol by name and model. Protocols are closed binary languages that differ family by family, and an unsupported device shows up on the platform silent, or not at all.

Pixa currently supports 18 tested protocol families spanning all three classes in this guide: Teltonika, Queclink, Meitrack, Ruptela, Galileosky, Atrack, Topflytech and Digital Matter on the advanced side; GT06/Concox, H02, GPS103 and Seeworld among the budget families; JT808 with JT/T 1078 video; plus Watch, OsmAnd, Omnicomm, EGTS and Wialon retranslation for re-streaming from other systems — with an expansion methodology aimed at hundreds of protocols. The up-to-date list is on the devices page.

A practical benefit of the unified platform shows here: however mixed your device classes, all their data appears on the same screens and in the same reports — the rep's car on a budget unit and the reefer truck on an advanced one sit side by side in live tracking and fleet reports, with only the depth of available data varying by hardware.

One final practical point: Wialon retranslation support means you can trial a new platform in parallel with your current system without touching device configurations — a low-risk way to test the platform on your real data before migrating.

Pre-purchase checklist

Run through these seven items before signing the purchase order:

• Have you written the required data list (position, fuel, temperature, driver ID, video…) and matched the class to it?
• Does the platform support this exact protocol and model? Ask for written confirmation, not a "works with everything" claim.
• Are there enough inputs for today's sensors and tomorrow's additions? Adding a fuel sensor later to a device with no spare input means replacing the device.
• If remote engine cut-off is required, does the device have a control output — and does the platform execute it behind an additional authentication step to prevent misuse?
• For fuel monitoring: did the vendor present a tank calibration table, or just promise "high accuracy"?
• For vehicles regulated by the Transport General Authority: does the setup meet the WASL integration requirements?
• Have you piloted a single device on the platform before rolling the purchase out to the whole fleet?

Above all, try before you buy: put one sample device on the live tracking screen and watch the data quality for a few days — real data settles what catalogues cannot.
