Announcement of EOSS-109/110

LAUNCH DATE: 29-July-2006
LAUNCH TIME: 7:30 am (13:30 UTC) second balloon 45 minutes later
LAUNCH SITE: Genoa, CO (Driving Directions)
GROUND STATION SITE: Deer Trail, CO (Driving Directions)

  IMPORTANT!! 

CHANGED AGAIN Friday Afternoon

Due to strong winds driving the flight track significantly towards the west into DIA's Class B airspace, we are moving the launch site to Genoa, Colorado (8 miles east of Limon - new driving directions linked below). The ground station will still be setup at Deer Trail and the initial preparation of flight strings will be carried out there. However, once the two payload trains have been assembled, they will be moved with student launch teams to the alternate launch site. The drive from Deer Trail to the alternate launch site is approximately 45 minutes. So, be prepared to move up your schedules to accommodate the scheduled launch time for the first balloon at 07:30 am MDT.

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:

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.
