Garmin commemorated the 20th anniversary of the Garmin GPS 155 receiving FAA TSO authorization late last week. The GPS 155 was the industry’s first FAA TSO-C129 approach-approved IFR GPS receiver. The device received FAA TSO approval on Feb. 16, 1994, and “laid the groundwork for future aviation milestones and set the standard for product development, eventually ushering in the foundational technology for what is now referred to as NextGen,” said Garmin vice president of aviation sales and marketing Carl Wolf. It was the first GPS navigation product that allowed pilots to fly in IMC throughout the departure, en route and approach phases of flight using GPS as their primary navigation source.
