Garmin® celebrates a GPS milestone in aviation

OLATHE, Kan.–(BUSINESS WIRE)–Garmin International, Inc., a unit of Garmin Ltd. (NASDAQ: GRMN), today
commemorates the 25th anniversary of the GPS 155 TSO – the
aviation industry’s first FAA TSO-C129 approach approved IFR GPS
receiver. The GPS 155 TSO set the standard for product development
within avionics, laid the groundwork for future innovations in GPS
navigation, and raised the bar for technological GPS advancements in the
aviation industry.

“Our steadfast commitment to design, develop and deliver
state-of-the-art avionics continues yet today as we commemorate the 25th
anniversary of the GPS 155 TSO and celebrate a breakthrough in aviation
navigation – one that pioneered the development for initiatives such as
NextGen,” said Carl Wolf, vice president of aviation sales and
marketing. “As we recognize this significant milestone in aviation, we
thank our loyal customer base and dedicated associates who make these
achievements possible, and look forward to celebrating many more for
years to come.”

On February 16, 1994, Garmin achieved a significant milestone by
introducing the GPS 155 TSO to the aviation industry—the world’s first
GPS navigation product to be fully certified to FAA TSO-C129, Class A1
standards for non-precision approach use. For the first time, pilots
could fly in instrument meteorological conditions (IMC) throughout the
departure, enroute, and approach phases of flight using GPS as their
primary navigation source. The introduction of the GPS 155 TSO would
eventually pave the way for the development of new, safety-enhancing
technologies that would leverage the high-integrity position data it
offered, such as moving map displays, terrain avoidance systems, and
synthetic vision.

With the GPS 155 TSO, aircraft operators quickly recognized the
operational safety benefits of modern era satellite-based navigation
that traditional navigation could not provide. Simultaneously,
antiquated and less accurate ground-based navigational aids (NAVAIDs)
were slowly phased-out. The benefits of GPS navigation were realized
throughout the industry as GPS not only offered a higher level of
precise navigation throughout the national airspace system (NAS), but
also provided instrument approach capability, which was especially
important for remote airports that did not have the appropriate funding
or accessibility to NAVAIDs.

Years later, the GPS 155 TSO would eventually pave the way for the
development of technologies that support the broader implementation of
airspace modernization initiatives, such as the Next Generation Air
Transportation System, better known as NextGen. Predicated on GPS,
NextGen significantly improves aircraft predictability, operational
performance and capacity throughout the NAS and offers efficiencies that
only GPS navigation can provide. These efficiencies result in reduced
flying time, lower approach minimums, minimized fuel burn and more. A
pillar of NextGen, Automatic Dependent Surveillance-Broadcast (ADS-B),
also relies on the precise position information only available from Wide
Area Augmentation System (WAAS) GPS. The GPS 155 TSO unquestionably laid
the foundation for future advancements in avionics that would ultimately
support global airspace modernization initiatives.

In 1998, Garmin would again celebrate another innovative first in the
aviation industry with the introduction of the GNS™ 430. The all-in-one
GPS, COM, VOR, LOC, and glideslope navigator, complete with a color
moving map, proved to be a significant technological leap in innovation
and navigation. Similarly, when the GNS 430 and GNS 530 received WAAS
certification in 2006, the most popular certified IFR GPS system to-date
gave pilots even greater instrument approach capabilities. In 2011, the
GTN™ 650 and GTN 750 were introduced to the marketplace as the first
touchscreen avionics certified for general aviation aircraft and have
proven just as popular as their predecessor.
