GEOMETRIC DILUTION OF PRECISION

E. R. Swanson

Peer Reviewed

Abstract: A graph is developed which gives geometric dilution for fixes obtained hyperbolically using information received from three stations. Only bearings from the user to the stations are needed. The approach can be characterized as oriented to the user rather than to system development and is particularly valuable in assessing station choices in redundant systems such as Omega. Dilution is shown to be minor even if all bearings are in the same semi-circle provided the central station is on a nearly central bearing.
