DIGITAL COMPUTER PROGRAM FOR ERROR ANALYSIS OF INERTIAL NAVIGATION SYSTEMS,
Abstract
This article is a collection of revised pages to the document, submitted in August, 1966, entitled 'Digital Computer Program for Error Analysis of Inertial Guidance Systems.' In addition to revisions several additions have also been made. The input trajectory tape format has been changed making two additional input constants for all error analyses necessary. The gyro non-g-sensitive drift error sources are active during all free flights unless changed by input. The accelerometer bias error sources can now be activated or de-activated by input. In addition, a note has been added on the output that describes the state of these error sources. The capability has been added to allow the aborting of the trajectory tape to enter into a free flight and allow resumption of the trajectory tape after an integral number of orbits. A note has been added on the output to denote trajectory abort times. The table of TG0P entries has been expanded from 12 to 50 to allow additional outputs. To use the TG0P table for phase changes, negative entries of time are now required. Additional input is available to allow a strapdown system to rotate at a constant rate during equations of motion propagation. Output in a co-ordinate system other than ECI or local horizontal is now available.
