Internet Gateway Stations:

Future I-Gaters:

Check out the EOSS I-Gate page for information on how to participate and why we need you.

Current I-Gate Station:

Guys, the prediction program used to determine the track of the balloon prior to flight can now output a prediction for the Rise, Closest Approach, and Set of the balloon for each of your stations. I have posted a prediction page for stations that I have been able to discover geographic coordinates. See the I-Gate prediction page for an example. The page will not be updated daily, however, it will be updated the evening prior to flight for I-gate planning purposes.

I have often been asked by iGaters when they should expect to either start receiving signals (AOS) or expect to see those signals disappear (LOS). This prediction page should answer all those questions for you.

Tracking and Recovery Info:

Help us build a database of the best RDF/Observation sites in Eastern Colorado. See the Observation Site Database page for ideas on what we'd like to see in this DB and if you're interested in the Balloon Track use of that database.

Notes:

Our Customer

EOSS. Yep, we're flying this one to attempt an altitude record. The current thinking is that we really have NO IDEA what is going to happen to the 7000 gram balloon. Well we have some idea, but, the balloon is old making its behavior unpredictable.

So we've decided to fly a second balloon on the same day with the same goal. To beat the altitude record. The thinking is, "why drag everyone out there and have an old balloon go bust unexpectedly ruining the day when a backup flyer can increase the odds of a successful flight and better shot at the record at the same time".

note: customers are welcome to submit detailed synopses of their flights or web links to their own web sites.
