Track 3D J-Track
uses orbit propagation. It takes an objects location and direction (a vector) and
calculates where it believes the object will be in the future if no direction changes
occur. For the shuttle, many changes occur, so we update vectors frequently.
Warning: This program is
computationally intensive. The faster the computer, the more usable.
The download may take a little while.
It loads 500+ satellites.
Known Bugs:
- Ground trace does not update.
- Selecting from "Select" dialog
rather than clicking on the Satellite does not update the "Statistics Dialog
box".
- Some satellites mysteriously orbit
through the earth.
- Occasionally "Center" does not
work.
Features which are too CPU intense
for JAVA:
- All counties/cities on map
- Weather patterns
- All satellites (this out of 9000 active).
The tracking system JAVA applet was
developed by Patrick Meyer, Tim Horvath, and John Jaap for exclusive use by Liftoff to Space
Exploration. It is intended for entertainment and should not be used for detailed
analysis.
