Telematics is a method of monitoring vehicles, trucks, equipment and other assets by combining GPS technology with on-board diagnostics (OBD) to track their movements on a computerised map. Also known as fleet tracking or GPS vehicle tracking, the term "telematics" blends "telecommunication" — the exchange of information using technology — with "informatics," the use of computers to gather, analyse and manage real-world data. Today, telematics is an essential management tool for commercial and government fleets of all sizes.

How does telematics work?

Telematics works by using a small tracking device — often called a black box — that plugs into a vehicle's OBD-II or CAN-BUS port. The device retrieves data generated by the vehicle, including GPS position, speed, engine fault information and g-force measured by a built-in accelerometer. A SIM card and modem within the device transmit this data over the cellular network to the cloud. Once in the cloud, the data is decoded and presented through fleet management software for reporting and analysis. Key data points captured include: Position and vehicle speed Trip distance and time Idling time Harsh braking and driving behaviour Seat belt use Fuel consumption Vehicle faults and battery voltage Fleet managers can then view and export reports, gaining actionable insights such as identifying top speeding offenders or vehicles due for scheduled maintenance.

What is the difference between telematics and GPS?

GPS (Global Positioning System) is a satellite-based technology that provides location data — it tells you where a vehicle is. Telematics is a broader system that uses GPS as one of its core components but captures far more information. A telematics device includes a GPS receiver alongside an engine interface, accelerometer, SIM card and input/output expander port. While GPS tracks location alone, telematics combines positioning with engine diagnostics, driver behaviour analysis, fuel monitoring, fault detection and more — delivering a complete picture of vehicle performance and fleet operations.

What is fleet telematics?

Fleet telematics is the application of telematics technology to manage a company's vehicles at scale. A fleet telematics system connects GPS tracking, on-board diagnostics, driver behaviour monitoring, and fuel management into a single platform — giving fleet managers real-time visibility across their entire vehicle fleet. It is used by logistics companies, construction businesses, government agencies, and enterprises across Southeast Asia to reduce costs, improve safety, and meet compliance requirements.

What devices are used in telematics?

The primary device used in telematics is a compact tracking unit — also called a black box — that plugs directly into a vehicle's OBD-II or CAN-BUS port. Its key components include: GPS receiver — for location tracking Engine interface — for diagnostic data Input/output interface (expander port) — for connecting additional hardware SIM card — for cellular data transmission Accelerometer — for measuring g-force and driving behaviour Buzzer — for in-cab alerts Through open-platform telematics, businesses can also integrate additional hardware and software such as dash cameras, electronic logging devices (ELDs), dispatching and route optimisation tools, mobile forms, remote diagnostics and weather alert systems.

What are the benefits of telematics for fleets?

Telematics delivers measurable benefits across six core areas of fleet management: Productivity — Improves customer service through real-time GPS tracking, trip reporting and dispatching and routing tools. Safety — Increases driver safety with in-vehicle coaching, behaviour reporting, collision notifications and reconstruction, and stolen vehicle location. Fleet Optimisation — Streamlines vehicle maintenance through predictive diagnostics and reduces fuel costs by tracking idling and inefficient driving habits. Compliance — Simplifies electronic logging, Hours of Service (HOS), IFTA reporting and vehicle inspections. Integration — Connects other software systems such as onboard cameras, CRM platforms and custom-built applications through an open platform. Sustainability — Reduces environmental impact and carbon emissions, and supports electric vehicle management. Additionally, telematics enables insurance savings by allowing fleet operators to share verified safety data with insurers to negotiate lower premiums, and enhances vehicle security through driver identification sensors that authenticate a driver's identity before the vehicle can be started.

Telematics is a method of monitoring vehicles, trucks, equipment and other assets by using GPS technology and on-board diagnostics (OBD) to plot movements on a digital map. Also known as fleet tracking or GPS vehicle tracking, telematics is now an essential management tool for commercial and government fleets across Southeast Asia — including Singapore, Malaysia, Philippines, Thailand, and Indonesia.

The meaning of telematics combines two disciplines: telecommunication (exchanging information using technology) and informatics (using computers to gather and manage data). Together, they form the foundation of modern vehicle telematics systems used by fleet operators worldwide.

What are telematics systems?

A telematics system is an intelligent onboard device that records and transmits near-real-time data from your vehicle — from speed and idling to fuel use, tyre pressure, and engine diagnostics. Understanding what a telematics system does helps fleet managers make faster, more informed decisions about their vehicles.

To track assets, information from the vehicle is recorded via a small, telematics device — also called a black box — that plugs into the OBD II or CAN-BUS port. A SIM card and modem in the device enables communication on the cellular network.

There are several key components of a telematics device:

GPS receiver
Engine interface
Input/output interface (expander port)
SIM card
Accelerometer
Buzzer

In addition to the hardware, the algorithm used for GPS logging is another critical factor because it impacts the quality and accuracy of the data. Read more about curve logging here.

How telematics works

A telematics device — sometimes called a black box or OBD dongle — plugs directly into a vehicle's OBD-II or CAN-BUS port and acts as the data hub for the entire system. It is the physical hardware that makes telematics tracking possible.

The telematics device retrieves data generated by the vehicle, like GPS position, speed, engine light information and faults. G-force measured by a built-in accelerometer in the device. Then the telematics device sends the data up to the cloud.

What data does a telematics system collect?

A vast amount of data can be processed and analyzed with a telematics device and other connected hardware or sensors, such as:

Position
Vehicle speed
Trip distance/time
Idling time
Harsh braking and driving
Seat belt use
Fuel consumption
Vehicle faults
Battery voltage, and other engine data.

Finally, the data is decoded and brought into the fleet management software app for reporting and analysis. With the software, users can view and export reports and gain business intelligence such as the top 10 drivers with the highest number of speeding incidents or vehicles that are due for scheduled maintenance.

Data analytics and machine learning offer a way to get further use from telematics data. For example, fleets can use benchmarking to see how their fleet performs on safety as compared to other similar fleets or understand if routes are structured in the best way.

Telematics data is sent from the vehicle to the fleet management software portal.

Open platform telematics

As technology has evolved, telematics has moved from a closed system to an open platform. Through open platform telematics, companies can integrate other types of hardware accessories, software, and mobile apps for greater efficiency and insight into business operations.

Popular telematics integrations include dash cameras, electronic logging (ELDs), dispatching and route optimization, mobile forms, remote diagnostics, or weather alerts.

The different ways businesses use telematics

History of telematics

The word “telematics” is a blend of two terms: “telecommunication” and “informatics.” Telecommunication is the exchange of information using technology. Informatics Open in new window refers to the use of computers to gather and analyze data and manage real-world systems.

In the 1960s, these two sciences (telematics and informatics) merged when the U.S. Department of Defense developed the Global Positioning System (GPS) to track the movements of U.S. assets and improve military communication.

Telematics owes its existence to three unique breakthroughs of modern technology: the internet, GPS, and machine-to-machine communication (M2M). The field of vehicle telematics also includes wireless safety communications, GPS navigation, integrated hands-free cell phones, and automatic driving assistance systems.

The benefits of telematics for fleet management

Fleet telematics delivers measurable, verifiable benefits across six core areas — making it one of the highest-ROI investments available to fleet operators in Southeast Asia. Telematics assists in six core areas of fleet management: productivity, safety, fleet optimization, compliance, integration and sustainability.

Productivity — Improving customer service by using real-time GPS tracking, trip reporting, and dispatching and routing tools
Safety — Increasing safety with in-vehicle driver coaching, risk and driver behavior reporting, collision notifications and reconstruction, and the ability to locate a stolen vehicle
Fleet Optimization — Streamlining vehicle maintenance with predictive maintenance abilities and remote diagnostics, and fuel management by tracking idling and other fuel-guzzling habits
Compliance — Electronic logging and Hours of Service, IFTA reporting, and vehicle inspections
Integration — Combining other software systems with telematics such as onboard camera technology or CRM software, and even building new applications
Sustainability — Reducing the fleet’s environmental impact and carbon emissions, plus managing electric vehicles

In insurance telematics, vehicle owners share safety data with their insurance company to help lower the cost of premiums, if they can prove safe driving habits. Essentially, telematics can help insurance companies better pinpoint levels of risk. (While not all insurance agencies are offering this telematics-based insurance, it’s worth discussing with your provider if you’re not self-insured.)

Another area gaining in popularity is the ability to increase vehicle security by integrating identification sensors into vehicles. This allows fleets to authenticate a driver’s identity before they can start the vehicle.
