Garmin Features GRA 5500 in Las Vegas

By By Frank Lombardi | February 27, 2013

Since 1989, Garmin (Booths N4412 and N5) has designed, manufactured, marketed and sold navigation, communication and information devices and applications—most of which are enabled by GPS technology. Garmin’s products serve automotive, mobile, wireless, outdoor recreation, marine, aviation, and OEM applications.

One of the latest devices to come out of Garmin’s Olathe, Kansas facility is the GRA 5500, a high-performance, all-digital radar altimeter for transport category, helicopter, business and general aviation aircraft. Using patent-pending digital signal processing technology, the GRA 5500 works to provide smooth altitude tracking resulting in a consistent and highly accurate altitude above ground indication, even over the most challenging environments like rough terrain, tree canopies, sand and choppy water.

The GRA 5500 “meets the highest altitude accuracy standards only previously seen in products for transport and military aircraft, providing pilots unprecedented confidence in their actual altitude,” said Carl Wolf, Garmin’s vice president of aviation sales and marketing. According to Garmin, the GRA 5500 is able to intelligently process hundreds of altitude measurements per second and apply advanced digital filters to help detect and mitigate false altitude returns. Industry-standard ARINC 429 interface allows the GRA 5500 to integrate with a breadth of Garmin integrated flight decks and flight displays, as well as third-party products.
