Truck Records provides with each SDL Data Logger a comprehensive Data Analysing Software package. Called GLapp, this software is installed onto your computer and enables you to collate, examine, analysis and subsequently report data.


Each of your vehicles equipped with an SDL Data Logger sends packets of data to Thoreb’s secure server located in Sweden.


Each packet of data has a unique label attached to it. This label consists of the vehicle’s identification (this can be the vehicle’s registration, chassis number or even fleet number) along with a time and date stamp corresponding to when that packet of information was recorded.

We call these individual packets of data Log Files.


Therefore if a vehicle is then subsequently involved in an incident or accident it is a very simple process to download the particular information required to find out what was happening, when and where it occurred exactly and this can often lead to precisely why the event arose in the first place.

Unlike other devices on the market, there is no requirement to access the vehicle itself in order to get hold of this important information. THis has a number of advantages.

  1. It eliminates the risk that the storage device may have been damaged.
  2. It eliminates the risk of data contamination between the vehicle and your computer.
  3. It saves a great deal of time.


Once the required Log File has been downloaded from the server in Sweden, GLAPP possesses an array of tools in order to analyse the information it contains. IT is possible to plot on a graph any of the lines of information the data logger is programmed to record. A typical example is plotting speed, brake applications, along with indicator lights and vehicle horn.

At the same time, GLAPP places the vehicle’s position onto a moving map showing the precise location of the vehicle at all times, and all the values mentioned above are plotted against a timeline, a timeline which comes directly from the Global Positioning system’s clocks themselves.

From this it is possible to print a report that shows the build up to and the actual events of the incident that initiated the requirement to look at the data.
