EOSS wishes to express our sincere appreciation to the stations above who iGated the balloon APRS telemetry onto the internet. Did you know I publish predictions for i-gates? I keep a list of everyone who has ever i-gated an EOSS balloon flight. You're all in the list so if you're wondering when the balloon will pop up over your horizon, check out this page for future flights.  Currently predictions are being made for 30 i-gates.

We are relying heavily on real time position information available on the net to allow the FAA controllers to have up to the minute location data to assist them in air traffic control.

Redundant stations for the balloon iGating provide excellent coverage. If you are able to iGate we invite you to join the Internet Gateway Team. Contact me (webmaster@eoss.org) to be put in touch with the coordinator. By joining the team, you are giving peace of mind to the iGate coordinator for that flight. He knows you'll be there and he can rely on you.

Naturally, anyone can iGate data onto the net and even if you aren't a member of the team we will welcome your contribution to the internet based tracking effort. If you callsign appears on the findu.com log, you'll be shown as a contributing station as those above are.

Having more than one station covering each APRS beacon means that should a station drop out momentarily, the others can often maintain the data flow.

Thanks again guys! The FAA (and EOSS) are very grateful for your assistance in this endeavor.

Future I-Gaters:

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

Current I-Gate Stations:

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 or maximum elevation, 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  

NEWS FROM ALPHA

Don, WA9WWS advises us this is the start of hunting season which means we must be very observant of men with guns. Wear bright clothing if possible, avoid camouflage on this day.

There will be some new hams from CU Boulder and possibly Metro State. Seek them out and congratulate them for their achievement. Let�s make them feel welcome to this fraternity.

Michael Willahan, science instructor from Chatfield HS, will have a payload onboard also. Please welcome him and his associates to our group.

Seek out Chris Koehler and tell him thanks for GSGC support this year.

There will be two flights of 3000 gram balloons. They will be launched within 10 minutes of each other � and will most likely land within 10 minutes of each other. Try to locate landowners early so we can expedite the first recovery and move the students to the second shortly thereafter. After EOSS 157 lands, part of the tracking team will be deployed quickly to recover EOSS 158. Please leave all payloads on the ground until the students can recover them. If it is windy, secure the payload string quickly.

 

Breakfast

  • Johnson's Corner (I-25 at exit 254 on the east side of the highway)
  • Arrive: 05:45 to 06:00
  • Depart: 06:30

If you want breakfast and to see the happy, early-morning faces, trackers will meet at Johnson�s Corner (I-25 Exit 254, east side) between 06:15 and 06:30.  Plan to leave for the launch site at 7:00 for a 7:40 launch.  Chris Koehler will have bagels and a generous assortment of Halloween leftovers at the launch site as a breakfast alternative.  Trackers also can meet at the launch site or in the predicted landing area.  I will bypass breakfast and go directly to the predicted landing area.
