Development Of A Personal Computer Simulation Program Of The LN-94 Inerial Navigation System

Abstract

This thesis develops a simulation that emulates a Litton LN-94 INS. Real time simulation is achieved for a stationary navigation case and a straight-and-level flight trajectory are provided to exercise the simulation dynamics. The user interface is simple and requires little previous knowledge to operate. The communication link with the MILSTD 1553B bus provide a realistic environment in which to collect and analyze data. The simulation is processed on an 80386 IBM compatible personal computer. A 23-state INS error model is implemented and integration is performed by a fifth-order Kutta-Merson routine. The simulation is interfaced to a plotting routine and data collection, both data type and rate, is controlled through the user interface. Simulation status and output is viewed from the simulation screen or on the MILSTD 1553B bus monitor. The simulation is programmed in C programming language. Program development is discussed and flow charts of the major modules provided. The simulation validation process is outlined and results are presented.
