Abstract
The advent of microprocessor technology found a very good application in the field of inertial navigation both in strap down and stable platform types. They are replacing the currently used minicomputers with smaller, lighter, less expensive and more reliable units. The great flexibility provided by the microprocessor may be used in many ways during system development, system modification, diagnosis and maintenance. The paper describes an inertial navigation system based on a stable platform stabilized in a Local Vertical North Slaved configuration, the computational requirement associated with it, the stability of the microprocessor for processing the information and the computer organization. The software support needed is also briefly discussed.
