Our FAQ

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)

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.

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).

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.

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.

Yes. There are also NO roaming costs.

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.
