Garmin has introduced its first radar altimeter, the GRA 5500, an all-digital design intended to bring extremely high altitude accuracy to general aviation aircraft.
The GRA 5500 is able to process hundreds of altitude measurements per second and apply advanced digital filters to help detect and mitigate false altitude returns, Garmin notes. The result is a radar altimeter with accuracy previously seen only in air transport and military radar altimeters, the company says.
