8.4 Reduced Bearing Accuracy Caused by Reflections

Big natural reflectors in the antenna unit’s surrounding are especially critical (e. g. mountains

in the back-side of the antenna, sharp rocky coasts or forests).

Especially if the directly arriving wave field is very weak due to a remote transmitter, high

mountains can cause reflections by receiving the signal better (due to their height) and

therefore also causing stronger reflections.

Fig. 172 Reflections at fixed locations

8.5 Overview of favorable and unfavorable Installation Locations

The drawings below show a summarization of effects to be considered while selecting

installation sites.

The first one focuses on effects in mountaneous areas, while the second one mainly applies

for obstacles within the main lobe of the antenna (refer to chapter 8.2).

For obstactles and disturbance sources within the main lobe of the antenna (refer to chapter

8.2), the same principal recommendations apply for VTS installations as for ATC installations

as shown in the second drawing.

Any deviation might lead to an increase in bearing errors beyond the bearing accuracy

achieved in reflection-free environments.
