STATE-OF-THE-ART radar altitude and digital signal processing

Designed to mitigate 5G interference, the Terrain Series radar altimeters feature the first major upgrade in radar altimetry solutions since the 1970s:

• Eliminate spurious terrestrial datalink spectrum interference including 5G, identified by an RTCA Special Committee to interfere with RF spectrums
• Retrofit capability with legacy aircraft - utilize existing antennas, control heads, and cabling as needed
• Robust, reliable, and rugged enclosure designed for use in mission-critical, military-grade environments
• Interfaces with standalone RAD-40 and RAD-45 display indicators for smooth and accurate LED AGL readings 
• Single and Dual Install kits available
