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 go are able to iGate we invite you to join the Internet Gateway Team. When we have more than one station covering each APRS beacon, should a station dropping out momentarily, the others pick up the slack quite nicely.
Thanks again guys! The FAA (and EOSS) are very grateful for your assistance in this endeavor.

Post Recovery Examination
Only EOSS-78's telemetry system was operating this time out. It carried two APRS systems. Both are posted below.
These files may be updated in the coming days if I receive additional logs from other individuals who monitored the flight.

Our descent rates were somewhat interesting. You can download the data above and run more detailed analysis but...
Below is the ascent rate for the entire flight.
And below is a "close-up" of just the descent phase. I thought it interesting that apparently the exceptionally high descent rate slowed then at around 46K feet began to build once again. Possibly some additional late fouling of the chute from the payload train.
