Editor's Note: This file was selected as MATLAB Central Pick of the Week
Inputs are the Keplerian orbital elements, planet properties, and ground station coordinates. Tabs include plots of spacecraft trajectory in the following coordinate systems:
Perifocal
Planet-Centered Inertial
Earth-Centered, Earth-Fixed (Planet-Centered Rotational)
East-North-Up
Groundtrack
Horizontal
Includes animation and slider controls for plotting the position of the spacecraft within the time frame defined from the time of periapsis passage, tau, to an arbitrary time, t_1. Four example .ini configurations are included to demonstrate usage.
Units are in SI (km) with options to select degrees or radians (as of version 1.1.0).
