Experimenters are welcome to submit websites for linking or overviews which I will post on a page on the EOSS website.
Future I-Gaters:
EOSS is always in need of I-Gate stations. Check out the EOSS I-Gate page for information on how to participate and why we need you.
Current I-Gate Station:
If you are present at your iGate during the flight try and monitor the tracking and recovery frequency. The ground station likes to check the frequency prior to launch to find out if any stations are out there ready to igate the traffic onto the net for the FAA to monitor.
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.
Your Log Files
Our technical committee members would also request you open a log file and record all the packets you hear and forward onto APRS-IS. Whenever there is a technical failure of a package it is always helpful to have the most complete dataset possible to attempt to determine the cause of failure and possible fixes. After a flight send your data files to me (webmaster) and I will distribute them to the appropriate payload builders. They appreciate these logs even if all goes fine during a flight.
Hi Trackers, Thanks to everyone for stepping up to this very long tracking adventure. We will be flying two 3000 gram balloons and hosting over 100 students. We have a great crew and I am sure we will be successful.
Some trackers will advance to the launch site where there will be some breakfast bagels at the launch site. Or they can stop in at Johnson�s Corner for those great cinnamon rolls. For the folks moving towards Sterling on I-76, look to meet at McDonalds in Ft. Morgan sometime about 5:30. Be sure to finish up and get on the road by 6:15 as we may have a long way to go from there. Mark and I will not be joining you at McDonalds as we are going to be booking it to the field and we will meet up with you there.
Be sure to fill up with gas Saturday night, bring warm clothes, water and munchies. Don�t forget Christmas presents for Alpha and his trusty sidekick Mark � really?
Due to the postponement, we have lost a few trackers. Please not the modified list of trackers below.
We will have some new folks on the tracking teams, please make them welcome. KB7MDF, Tim Chapman will be using his Arrow Antennas for DF adventures.
