In our FAQs, we answer the most frequently asked questions about our intelligent telematics solutions, our products and services, and the web-based MOBIDAT portal. If you have any further questions or individual inquiries, please feel free to contact us by e-mail, phone or via our contact form.

What is a telematics system?

Telematics links telecommunications with information technology. Telematics systems automatically record activities and display them on a PC. The information is exchanged between computers via remote data transmission. Vehicles and persons operating worldwide are mapped in this way. This eliminates the need for time-consuming and extensive notes. Complete records of exact activities, such as gritting, clearing, etc., are created.

The benefit:
>> Save time and costs
>> To increase the quality & efficiency of your operations
>> Reduce costs

What is GPS?

The GPS (Global Positioning System) satellite system was originally installed by the US Department of Defense. The intention was to achieve a higher precision of control for military purposes. The U.S. Congress approved the funds for installation only on the condition that the GPS system would also be made available for civilian use.

For this reason, the GPS satellites transmit two different signals: an encrypted very precise signal for NATO (P) and an unencrypted one (L1). The civil signal (L1) can be received and used by anyone at any time, worldwide and free of license fees (e.g. for car navigation).

The GPS satellite system is subject to constant improvement. Changes may affect the accuracy and/or performance of the GPS receiver. The sole responsibility for the accuracy and maintenance of the GPS system rests with the United States.

The achievable accuracy for the civilian signal today is approximately 10 meters. Before May 2, the signal was artificially distorted by the USA (SA, selected Availability). This limited the signal to about 100m. It can still happen today that in crisis situations the signal is artificially distorted in certain areas.

Currently, there are about 30 satellites (24 productive satellites, plus correction and reserve satellites) from six orbits in orbit. There can be up to 12 satellites above the horizon. The MOBIDAT GPS receivers can receive up to 12 satellites simultaneously. Provided there is visual contact and the position can be calculated exactly. This is always done when a MOBIDAT device has a clear sky above it. Often, the position can already be calculated in halls with wooden or plastic roofs. Dense cloud cover or foliage can impair GPS reception. The time to first fix (TTFF) is significantly reduced by the Assisted GPS function. With a clear view of the sky, the TTFF can be broken down to a few seconds. (see also http://www.nasa.gov)

What is Galileo?

Galileo is an independent European civil satellite navigation system that is being developed for worldwide use. Galileo is an independent, high-precision system for determining location and measuring time – worldwide and at any time. The following five services for different applications are planned for Galileo:

  • Open Service (OS): The open service enables the determination of the own position. It also provides the exact time so that the speed of movement can be calculated. The open service is to be provided unencrypted and free of charge.
  • Commercial Service (CS): The commercial service is even more accurate in determining position than the open service due to higher transmission rates as a result of additional transmission frequencies. For this reason, it is encrypted and subject to a charge.
  • Public Regulated Service (PRS): The public regulated service is intended to help government agencies such as the police, border guards, customs and security bodies in the performance of their sovereign tasks. Its signal is encrypted, particularly stable and secured against interference and deception.
  • Search and Rescue (SAR): Most emergency radio beacons today are operated via the COSPAS-SARSAT satellite system. Galileo will improve these SAR capabilities by allowing the position of emergency beacons to be detected in real time and located with an accuracy of a few meters. Feedback to the distress sender/victim will also be created.
    Safety of Life (SoL) service: this encrypted service is designed for user groups where guaranteed accuracy of position and time determination is important. This mainly concerns the areas of transport (aviation, shipping, rail transport).
  • Galileo services can be used, for example, in aviation for various navigation applications, including air traffic control, in shipping for safe navigation with electronic nautical charts, in rail traffic for train control and monitoring systems, in road traffic for destination guidance, in driver assistance systems, in automatic, electronic emergency calls (“eCall”) or in cross-modal operations for monitoring hazardous goods transports and cargo tracking.

Galileo services can also make a significant contribution in geodesy, agriculture and fisheries, emergency and rescue services or in the leisure sector – for orientation in the field or on bodies of water. In addition, other Galileo applications are constantly being developed, designed and tested, e.g. in banking, finance and insurance and in the energy sector, in environmental protection and management, and in mobile communications.

What does georeferenced mean?

The process of georeferencing links a position or location information on the earth (“geo-“) with the information of the earth image (map, raster file, postal address)  (see also http://de.wikipedia.org).

Why do you need the sim card?

Similar to a cell phone, the sim card is used to identify the device in the telecommunications network. This chip card is placed in a MOBIDAT device to enable data transfer via GSM.

Which Internet browsers are supported by the MOBIDAT portal?

Browser from version
MS Internet Explorer 7.0
Mozilla Firefox 9.0
Google Chrome 1.0
Apple Safari 4.0
Opera 9.0


Which telecom providers are supported?

Basically all of them. In Germany, very good experiences have been made with T-D1 and Vodafone (D2) due to the high network coverage. In Austria and Switzerland, all GPRS-capable networks have been supported so far.

Does the system also work abroad (as seen from Germany)?

Yes. There are also NO roaming costs.

Can subcontractors also be integrated into the system?

Absolutely. The system is even designed for this. Subcontractors are integrated into the platform. The contract is even integrated so that invoicing can take place via the platform.

What does PortalNG actually mean?

N: New

G: Generation

How do I order spare parts?

Spare parts as well as accessories can be ordered directly via our support team. Please understand that a written order is necessary due to liability and documentation.

Why is it not possible to log in to the portal?

  1. The registration is done by mistake on the predecessor portal http://www.mobidat.com/. However, other access data is required for this portal, and it will also be switched off after a transition period. The PortalNG can be reached under the URL http://portalng.mobidat.com/. Note: no “www.” may be placed in front of this URL!
  2. Part of the login data was not entered correctly. In this case, the login data should be compared with the data on the letter handed out. In particular, the password should be case sensitive. In case of a forgotten password, another user with administrator rights can assign a new password, or a new password is requested from MOBIWORX.
