Abstract
A microcomputer program to solve the complex task of
air-borne navigation was developed to demonstrate the
practicality of replacing costly general purpose digital
computers with relatively inexpensive dedicated microcomputers
on-board naval aircraft. The microcomputer
program showed that microcomputers have sufficient speed
and accuracy to solve the navigation problem. In order
to overcome the microcomputer's major deficiencies, speed
and accuracy, special arithmetic subprograms based on
table look-up were developed to trade inexpensive memory
for more speed. An application of graph theory in the form
of process graphs was made to facilitate the development
and documentation of the navigation program. To aid in
the testing of the microcomputer program, a Fortran simulation
program was developed to confirm the results of an
error bound analysis of the navigation program.
