In fact, the satellite sector is far from being a minor aspect, in terms of value, of the potential services that can be provided on the ground. The satellite signal can be used to help with navigation, assistance, safety, choosing a route by land or sea, and fleet management; even taxis are beginning to use satellite signals on board.
I virkeligheden udgør satellitsegmentet en meget lille del af de potentielle tjenesteydelser, der kan opnås på jorden i forbindelse med udnyttelse af satellitsignaler til bistand ved navigation, redningsaktioner, sikkerhed, rutevalg, styring af bilparker, ja selv taxier begynder nu at kunne modtage satellitsignaler.
