Which of the following satellite navigation systems has Full Operational Capability (FOC) and is approved for specified flights under IFR conditions in Europe?
Learning Objective 062.06.01.01.01: State that there are four main GNSSs. These are: USA NAVigation System with Timing And Ranging Global Positioning System (NAVSTAR GPS); Russian GLObal NAvigation Satellite System (GLONASS); European Galileo (under construction); Chinese BeiDou (under construction).
We have to go with whatever the learning objective says on this, and as the most recent LO states that only NAVSTAR/GPS and GLONASS are functional, any other options are not correct.
GLONASS is not certified for use in Europe for many reasons. The trust in the system is very low, and it does not use the WGS-84 database, so is not easily compatible with other GNSS systems, such as NAVSTAR/GPS, which is proven and well certified.
