II Morrow Inc. NMC 2001 - Basic Concepts; Apollo Navigation Management System

Basic Concepts
The Apollo NMS (Navigation Management System) uses a variety of
remote sensors to provide a broad range of information. The “heart” of
the system is the NMC (Nav Management Computer). The interface
network is called NAVNET
TM
. The NMC interprets data from the
sensors to determine position, course, wind, altitude, and fuel
information. Some features require specific sensors. For example,
Altitude Assist features requires a Fuel/Air Data Sensor, or an altitude
encoder. Multiple position sensors and external
instruments/annunciators may be used for redundancy. The system
approach allows additional components to be added at any time.
