GROUND VS. SATELLITE WEATHER

摘要

Probably the biggest argument that commercial weather services use to compete with free FIS-B is that they are satellite-based and you should be able to receive it virtually anywhere on the ground or in flight. This compares with FIS-B from the FAA that is broadcast from ground stations, meaning you seldom receive the information when on the ground and usually must be at least a few thousand feet above the ground. Does that matter?
