Differential LORAN (DLORAN)

Differential LORAN (DLORAN) is an enhancement of the long-range navigation system that uses ground-based radio signals to help ships and aircraft determine their precise location. By comparing signals received from a network of fixed stations, DLORAN corrects for small errors and improves accuracy beyond standard LORAN. It works by referencing a highly accurate reference station and applying real-time adjustments to the position data, resulting in more precise navigation. This system is valuable in areas where GPS signals might be unreliable or for safety-critical operations requiring high positional accuracy.
