IMPROVING THE ACCURACY OF NAVIGATION AT SEA

Movements in the hyperbolic lines of position due to propagation anomalies, such as land-sea paths or ionospheric height as in Omega and Decca, would give rise to either fixed or variable error. These errors are discussed when dealing with each navigational aid, and a scheme is presented for the mechanization of an integrated navigation system. Certain aspects of the integrated system are discussed, among them the ability to estimate the probability of a resulting fix being where it said it is, and also the probability contours. The hardware requirments and components of an integrated navigation system are also discussed at some length.
