“"Before GPS, pilots used stars, then radio beams, then guesswork. Now they use satellites."”
The Global Positioning System became fully operational in 1995, but its origins trace to the 1973 merger of the U.S. Air Force's 621B program and the Navy's Timation satellite project. The first GPS satellite launched in 1978. By 1995, a constellation of 24 satellites provided global coverage. GPS was opened to civilian use after the 1983 Soviet shootdown of Korean Air Lines Flight 007, which had strayed off course due to navigational error. President Reagan ordered the system made available for civilian aviation. The first handheld GPS receiver for aviation—the Magellan NAV 1000—appeared in 1989. WAAS (Wide Area Augmentation System) became operational in 2003, enabling GPS precision approaches without ground-based infrastructure. Today, GPS is the primary navigation method for virtually all aircraft, from airliners to ultralights. The next generation, GNSS, integrates GPS, GLONASS, Galileo, and BeiDou for redundancy and accuracy measured in centimeters.
GPS-based RNAV (Area Navigation) approaches allow precision guidance into airports without traditional VOR or ILS infrastructure, reducing costs and increasing access—a technology that directly benefits pilots flying into smaller airports like KLVK.
