Introduction
Terrestrial Interference like WiMAX, BWA and IMT has caught a lot of attention from the users and satellite operators because of the widespread deployment of these wireless networks and their persistent impact on C-band Fixed Service (FSS). Among other interfering sources, aircraft altimeter is also a common source of interference for C-band satellite reception. Even though it is not generally known to users, its impact on C-band satellite service can be significant. This article will examine the causes of interference due to aircraft and how to mitigate its impact.
