Abstract: Several methods for accuracy enhancement of the Omega navigation system have been devised. Most are based on the fact that system errors are nearly constant throughout a local geographic area, even at points several hundred miles apart. The term "differential" Omega applies to any method of accuracy improvement based on this approsimation. Micro-Omega is an automatic version of differential Omega, which treats the combination of monitor station and navigational receiver as a single, fast response, closed loop control system. This provides correction of long-period errors due to skywaves and Omega base station instabilities as well as the rapid fluctuations caused by atmospherics. Micro-Omega is an outgrowth of technology developed for Raydist, and ultra-precise radiolocation system. Raydist was also used as a measurement standard during test and evaluation of Micro-Omega. Extensive hardware commonality among the two system with the capabilities and advantages of both.
