Satellite orbit programs utilizing the graphics capabilities of the microcomputer.

Abstract

It is important for a student of Space Science to have the opportunity to thoroughly understand the principle of an artificial satellite orbit. This thesis consists of four computer graphics programs that will enable the student to see what an orbit is and how it works. The first program demonstrates the shape of an orbit in two dimensions resulting from initial altitude, speed, and flight path angle. The second program draws an orbit in three dimensions around a sphere based on the input of the classical orbital elements. The third program traces the ground track of a satellite over a map of the earth. And the fourth plots the ground track of a geosynchronous satellite over a map of the earth. The student can learn about orbits by entering the orbital elements and viewing the resultant orbit.
