TERRAIN SERIES RADAR ALTIMETERS MITIGATE 5G RADALT INTERFERENCE WITH THE TERRAIN SERIES YOUR RADAR ALTIMETER REQUIREMENTS ARE CHANGING. HOW WILL YOUR OPERATIONS BE AFFECTED? The FCC recently approved the use of a previously reserved radio frequency (RF) spectrum in the lower C Band (3.7 Ghz - 3.98 Ghz) in support of 5G systems deployment throughout the United States. In practice, this means that the spectrum, previously reserved for low power applications, will now be available to the telecommunications industry for high power transmissions. These high power transmissions have been shown to affect the ability of radar altimeters to accurately provide flight crews with altitude measurement readings. These altitude readings are critical to the aviation industry for safe approach and landing operations, for both manned and unmanned aviation. Many of the radar altimeters currently fielded by operators today may experience performance degradations and incorrect altitude readings this is why we are introducing the TSO’d 5G-mitigating TERRAIN Series.
