The Global Positioning System (GPS) consists of a constellation of 24 high-altitude satellites with very accurate atomic clocks, along with a global network of satellite tracking stations and sophisticated ground processing stations, that together pr

This paper gives a closed-form solution for the minimum error one can expect from a linear prediction filter applied to a clock for which the fractional frequency power spectrum consists of white noise and the integral of white noise. Measurement err

Cross correlation has been used for detection and parameter estimation of moving targets. Various correlation techniques consist, essentially, of methods to estimate the spectrum of the correlation product. The power spectrum of the lagged product is

Recursive Bayesian equations are given for estimating the states of a system, given the sequence of inputs, outputs, and the probabilistic interdependences from one time to the next. Equations are derived for the case of a nonlinear system with norma

The pattern classification problem is stated in terms of an ideal system and a model system. The ideal system gives the true classification of each input pattern while the model system gives an estimate of the probable classification of each pattern.

Nonlinear system state estimation theory is applied to the magnetic gradient navigation problem. This approach removes the heading constraints of previous methods and permits an essentially arbitrary path to be followed. The method was tested on a si
