Internet Gateway Stations:as seen on Findu.Com
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 29 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. Experimental Systems
note: customers are welcome to submit detailed synopses of their flights or web links to their own web sites. PhotosLaunch Site Recovery Area
AudioNote: more than 90% of the T&R traffic occurred on repeaters out of the range of the monitoring station. Thus most of the traffic heard here is relayed into the main net. It may still prove interesting and useful. Pre-Flight
