摘要
In an exemplary embodiment of the present invention, a navigation system suitable for use in civilian airspace includes a first precise positioning service (PPS) global positioning system (GPS) receiver in a first line replaceable unit (LRU). A second standard positioning service (SPS) global positioning system (GPS) receiver in either the same line replaceable unit (LRU) or in a second line replaceable unit (LRU) is also included. The second standard positioning service (SPS) global positioning system (GPS) receiver is suitable for at least one of certification, upgrade and replacement independent of the first precise positioning service (PPS) global positioning system (GPS) receiver.
