GNSS signal in commercial use
Today almost every mobile device uses GNSS signal for many applications, very often we see applications and gadgets integrated in daily used apparatus using the GNSS signal. Navigation systems are integrated in cars at the production line, but also in agricultural equipment like ploughs or trucks the navigational systems are integrated when build. To be sure the system is functioning all right before the car or truck is leaving the production site, the GNSS signal must be available inside the production line. And during the live time of the car or truck it will be inside a garage for maintenance, it saves time and money when the GNSS systems can be checked during maintenance inside the garage.
