Book Description
A navigation software simulation program was developed, checked and verified as a part of an investigation into the feasibility of standardization of software for aircraft Inertial Navigation Systems (INS). The program can be used to simulate the unaided INS navigation errors resulting from a partiular mechanization of the navigation equations on a given digital computer. Technical data required for the Simulator Program design was obtained from survey of typical INS navigation software. The survey results revealed commonality in navigation computations employed in various INS, configurations, the gravity models approximations used in the computations, the commonality in the frames and the transformations symbology employed in the computations and the software interface between the INS computations and the Avionics-System computations. The navigation software simulation program is coded in Fortran IV for use on either IBM-360 or CDC-6600 computers. (Author).
