QUALITY:
Quality Factor is a numerical display that indicates the reliability of
position data and determines the weight of the VLF/Omega Sensor
input to the composite position. The number will range from 2 to 7
(with 2 being optimum) in the primary navigation mode, and from 8 to
99 in the dead reckoning mode (DR). NO STD will be displayed if the
rubidium frequency standard in the RPU is unstable. (
