Experimenters are welcome to submit websites for linking or overviews which I will post on a page on the EOSS website.

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.
Breakfast for the trackers will be at the Windsor Launch site. We will leave the launch site and go directly east to near Greeley.

EOSS-180 Launch |

EOSS-180 AE0SS-11
The AE0SS-11 APRS system suffered a catastrophic accident that ripped the top off the unit disabling it. Pictures are available. This happened immediately after the first packet transmitted post burst. So we did compile a complete record of the ascent phase of the flight. The location of the touchdown was captured on scene by trackers with their GPSs, NOT by AE0SS-11.
The LOG from the AE0SS-11 system continued to record for several additional packets after transmitter failure. The log is annotated below by Mike Manes and has been used to create the map files
