Looking for a demo? When 'A picture is worth a 1000 words.' This is a simple AVI that can be used to demonstrate the effects of eccentricity on a orbit.
It starts looking down on the a circular orbit around the Earth as it spins. As eccentricity increases the orbit stretches out to an elliptical path. The apogee and perigee are shown as green and red respectively. Then it returns to a circular orbit.
The intention was to provide a means to stimulate discussion in a training environment and to point out significant attributes of a satellite's orbit from a general perspective. Specifically designed for use as a training aid and provide a background during discussion. This can be used to show eccentricity in an orbit, deference between circular and elliptical orbits, where the apogee and perigee are in the orbit, standard orbits or as part of orbit raising discussions.
This AVI contains 720 frames and runs in 24 seconds start to finish. It is rendered in letterbox format, non-interlaced at 3 resolutions 1280x720, 1024x600 and 736x398, compression was using Cinepak Codec by Radius with the quality set to 100%. The final render stops one frame from the starting point so it is set to loop smoothly when set to repeat using media player or the application of your choice.
There are no textures or models included in this package it only includes the AVI and JPG files.
