Loran-C HYperbolic Coordinate Converter Set (AN/AYA-4). Volume II.
Abstract
The report contains the three sections. The theoretical development section shows the mathematical derivations of all equations implemented and a complete list of all the subroutines, program logic flow charts, computer instruction listings, and a tabulation of temporary memory parameters and their locations. The overall program is best understood by referring to the overall system flow diagram and the listing of the MAINLINE program. These two, in turn, refer to subprograms, subroutines and operations which are listed separately in conventional flow diagram form as well as in DIVIC language form. The DIVIC language is a special language, developed for this computer organization; it provides the necessary instructions to the computer for the particular program. The hardware development section discusses the hardware involved in the AYA-4 system. Items covered involve the operation, method of implementation and the electronics involved in the computer; A-D, D-A Converter; Controller; Indicator; and Power Supply. The LORAN-C error analysis appendix covers the Loran-C error analysis for 25 existing triads. Station coordinates, base line lengths and coding delays, propagation velocity, earth's parameters, and the station transmission ranges are presented for each triad. The mean and standard deviation for latitude, longitude, and radial error in feet are given along with the maximum and minimum values of radial error. In addition, an error contour map is given for each triad. (Author)
