II Morrow shifted focus from marine business to development of package process automation technology for UPS such as vehicle management systems, automated high speed package sorting systems, as well as delivery and tracking systems. In 1999, II Morrow was renamed to UPS Aviation Technologies, and re-focused towards modernizing UPS' Boeing 7xx series Heavy Iron Transport Category Aircraft fleet, as well they also re-entered the general aviation marketplace. It certified the first Gamma 3 WAAS GPS engine for FAA Certified Precision GPS approaches. The new certified WAAS engine yielded vertical and horizontal accuracy of one meter RMS in guidance into airports without existing ILS approaches. This GPS technology met the FAA's TSO-C146a primary navigation standards for en route, terminal and approach phases of flight—with WAAS augmentation as the sole means of navigation. This primary GPS "sole source" navigation capability was integrated into the CNX-80. The CNX-80 WAAS GPS/COM/NAV integrated navigator was the first product in the industry approved for primary GPS navigation. It also enabled LPV "glidescope" approaches without requiring ground nav aids. New LNAV (GPS) approaches provide the accuracy and safety of an ILS—without the ground-based localizer and glideslope equipment. Later, the CNX-80 was renamed the GNS-480, under Garmin.
