A Digital Computing Device for an Inertial Navigation System,
Abstract
The operation of a computer serving an inertial navigation system with stabilization in the horizontal plane requires the solution of a system of three nonlinear differential equations involving, as variables, the latitude and longitude of the moving object, and the angle which characterizes the position of the plane in the azimuth with respect to the geographical system of coordinates. Unfortunately, a computer designed to deal directly with these equations involves a number of technical difficulties leading to substantial errors. By introducing the Rodrigues-Hamilton parameters, the author reduces the computing function essentially to the solution of four linear differential equations equivalent to the original system. One apparent advantage of a computer so designed is that no shift to a second coordinate system is required in the case of navigation near the poles. (Author)
