Figure 1. Balltrack Online Input Parameter Example<br />
Figure 2. Balloon Trajectory Input Parameter Example<br />
In summary, it was found that Balltrack Online was the most accurate program <strong>of</strong> the two models so long as<br />
good information was input. A more detailed comparison <strong>of</strong> the actual versus the predicted landing sites lies on the<br />
appendices. In order to be accurate, the Balltrack Online model required accurate ascent and descent rate<br />
information whereas the Balloon Trajectory automatically input those values.<br />
V. Flight Tests and Results<br />
Four flight tests have been conducted thus far. They have all served to test the tracking system and to develop a<br />
comprehensive set <strong>of</strong> launch procedures that will ensure the most successful flights possible. Each <strong>of</strong> the four flights<br />
is summarized below.<br />
A. Flight One<br />
Flight one was a test flight to evaluate the performance <strong>of</strong> a still camera at above 18 km and to test the Garmin®<br />
18 GPS above that altitude as well. A secondary payload <strong>of</strong> a meteorological weather sonde was carried for the<br />
