The Omega Navigation System was a global radio navigation system developed in the 1960s. It utilized a network of ground stations that transmitted low-frequency signals, allowing ships and aircraft to determine their position anywhere in the world. The system was particularly useful for long-distance navigation over oceans. Operational until the late 1990s, the Omega Navigation System provided accurate positioning information, but it was eventually replaced by more advanced systems like GPS (Global Positioning System). Despite its discontinuation, Omega played a significant role in the evolution of navigation technology and laid the groundwork for future systems.
