EOSS wishes to express our sincere appreciation to the stations above who iGated the balloon APRS telemetry onto the internet.
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. 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.
Having more than one station covering each APRS beacon means that should a station drop out momentarily, the others maintain the data flow quite nicely.
Thanks again guys! The FAA (and EOSS) are very grateful for your assistance in this endeavor.

Doug Crandall, KB9ZWL, sent along these files (in zip archive). If you use UI-View, you can replay the flight.
Mark Patton was curious about the altitude/descent rate issues between two APRS systems on a single balloon. Here is his chart and below that a link to the Excel spread sheet that generated it.
