It seems appropriate first to define and explain the term Area Navigation that lately has almost become a slogan in discussions on short-range radio navigation aids. The term itself does not convey much because virtually any radio navigation system permits navigation in the area of coverage of the associated ground stations; for a systematic classification of navigation systems, the term Area Navigation (herein called ANAV) is unsatisfactory. It can be understood only in the context of air traffic control requirements. For a long while the requirements of short-range navigation systems were almost exclusively governed by the needs of air traffic control systems based on an airways concept. When during recent years A.T.C. methods became less associated with a fixed route structure, especially in the terminal area, the requirements to be met by a navigation system changed accordingly. There now appears to be a general trend for area navigation capability to become available as a substitute for a point-to-point navigation system.

The analysis an influence of reflections from the underlying surface, atmospheric noise, the Earth’s surface, cosmic noise and signal attenuation of the signal the atmosphere, as well as the flight dynamics of the aircraft (AC) on the signal/noise ratio and, accordingly, on the accuracy of AC navigation definitions by using consumer equipment of the satellite radio navigation systems. The analysis an influence of reflections from the underlying surface on the equipment operation quality of the satellite radio navigation systems consumers is carried out by using the Beckman model, in accordance with the earth’s surface appears to consist of flat faces with an arbitrary slope. It is noted that reflections from the underlying surface have a greater effect on the quality of functioning of the consumer equipment of the satellite radio navigation systems in the tracking signal mode than in the detection mode. In this case, the influence of reflections increases with decreasing flight altitude and an increase in the angle of heel of the AC in the direction of the navigation spacecraft.
