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.
