GPS Architecture
The GPS Positioning Concept
• Two principal pieces of information are required to determine a GPS position: ➢Position of each satellite ➢Range from the satellite to the user
What might a Flight Management System do for a pilot?
•Position •Airspeed •Groundspeed •Altitude hold •ETE / ETA •Heading •Course
• Ground Track • Fuel Burn
Once the Waypoint is set up in the receiver, the pilot simply treats it as though it were a real VOR
Programming the RNAV
Flight Management Systems: A Definition
• A minimum of four satellite signals are required to solve for an unaided, unique, position and time solution.

User Element
• Consists of antennas and receiver/processors on board an aircraft, automobile, ship, cellular telephones and other new items like watches that provide positioning, velocity and precise timing to the user.
