Ultimate Guide to Fleet Telematics - Everything Explained Step by Step (2021)

The word Telematics is a combination of two words. "Tele," a Greek word that means “at a distance.” At the same time, the word matics is short for informatics, which means information. Telematics is a discipline incorporating the practice of information processing.

Telematics is the technology used to monitor a wide range of information relating to an individual vehicle or an entire fleet.

However, there is a lot more to know about telematics and telematics devices. We have explained everything in detail in the below section of the article. If you are interested to know about fleet management telematics, then keep on reading.

1. What are telematics devices?

Telematics devices are unique instruments or trackers in simple words. Different insurance companies provide these instruments to their customers who install them in their cars. These devices feature built-in GNSS receivers that collect data from multiple GNSS satellites for position calculation.

Apart from that, they also collected different information from the vehicle using the inertial navigation sensor. Telematics devices collect information about the host vehicle's speed, altitude, total distance traveled, and position.

Just as we mentioned earlier, these devices use multiple sensors for the collection of data. It was just a basic intro to telematics devices. Let's take a look at how these devices work.

2. How does telematics work?

Fleet management telematics devices consist of multiple sensors. Each sensor collects different types of information. This information is then processed for final decisions. Here is how these devices work.


Each fleet management telematics device consists of an accurate GNSS or GPS sensor. The word GPS is used because people are familiar with it; however, there are multiple systems just like GPS.

The GNSS sensor of a telematics device collects feed from multiple GNSS satellites orbiting the earth in Medium earth orbit. At least four satellites are required for position and time calculation. Satellites send their signal, which passes through several layers of the atmosphere and reaches the telematics devices.

The receiver uses the signal to calculate the satellite's position and uses that position information to calculate the car's position. Usually, the higher the number of visible satellites, the better the receiver's positioning ability.

Inertial Sensor

Apart from a working GPS/GNSS sensor, fleet management telematics devices also possess another type of sensor. It is commonly known as the inertial sensor or the IMU. This sensor consists of two sub-parts, i.e., the Gyroscope and the accelerometer.

The Gyro sensor of the IMU collects the host vehicle's attitude information such as roll, yaw, and pitch angle. It is a rotating unit that points in a fixed direction and is mounted on the host with Gimbal's help. 

When the host vehicle takes a turn, the gimbal rotates with the host vehicle, but the gyro continues to point in its initial direction. An angle is created between the gyro and the vehicle's approach, which gives information about the vehicle's attitude.

For ground vehicles, a 2D gyro is sufficient because there is no pitch angle. However, for aerial vehicles, the pitch angle is also involved due to which a 3D gyro is used. The IMU sensor collects this information.

However, for acceleration, velocity, and position information, the IMU sensors are equipped with accelerometers. These accelerometers are quite sensitive and collect even the slightest acceleration of the vehicle.

Using the above-mentioned sensors, fleet management telematics devices collect information about the host vehicle. This information is then used by the agency for different applications.

3. Differences between fleet management and telematics

Since both fleet management and telematics are a bit similar, therefore, most people confuse them as one system. However, there is a significant difference between fleet management and telematics.

Let's take a closer look at both systems and see how they are different from each other.

Fleet management systems are usually software that know all the information about the vehicle's specifications. Apart from that, it stores the vehicle's documents securely. Moreover, fleet management also keeps a record of the maintenance and parts history.

In addition to this, transaction reporting such as fuel receipts and repair invoices are also some of the main responsibilities of fleet management.

However, telematics devices work completely differently from fleet management.

They provide information about the vehicle’s true location, speed of the vehicle, and attitude information. Apart from that, telematics devices also give alerts when the vehicle escapes from a virtually fenced location (geofencing).

It also provides information about the vehicle's trip history along with the fuel economy. It can help calculating the most economical route for the user.

4. How would telematics help a fleet owner?

Telematics can help the fleet owner in many ways. They capture important information about the operation on the road. Driver behavior and safety along with the health of the vehicle.

Telematics also allows businesses to increase their operational efficiency by radically improving their visibility into their operations.

Since these devices are providing real-time data, therefore, businesses can uncover new ways to save money and time. They can also help to improvise customer service by using updated information about the fleet movement.

5. How to Choose Fleet Telematics Providers?

While choosing a fleet telematics provider you need to ensure the following points. Keeping these points in your mind will help you select the best fleet telematics providers in no time.

GPS Tracking Systems

The first and the most important thing to keep in mind while selecting a telematics tracking system is GPS tracking. You need to ensure that the company is providing real-time tracking with the help of different GNSS.

GNSS provides information about the vehicle's exact location. It also provides route history about the host vehicle along with real-time economical route calculation. With GPS/GNSS companies can make virtual fences and get alerts if the vehicle escapes the fenced location.

DOT Compliance

Another important thing to consider while selecting a fleet telematics provider is DOT compliance. It helps create and manage the driver's inspection report. Due to the DVIR, you can know if the driver has completed the commercial motor vehicle inspection.


Fleet telematics providers also provide commercial video equipment to the fleet owners. These tools provide better viewing angles to the drivers which aid them during their movements.

Apart from that they provide information about the sides and rear of the vehicles which prove helpful in minimizing accidents.

6.Final Words

Reliable navigation, positioning and timing solutions are quite critical nowadays. Especially for fleet owners it can be a real game changer. It is because with the help of these fleet telematics services you can keep an eye on your fleet and individual vehicles anytime and anywhere.
