LAUNCH DATE: March 4, 2007 (Weather Delay to Sunday)
LAUNCH TIME: 7:00 am MST (14:00 UTC)
LAUNCH SITE: Windsor, CO (Driving Directions)
On Air Nets
Check into the weekly EOSS net every Tuesday evening, except the 2nd Tuesday of the month when we hold our face to face meetings.
Pre-Flight Coordination Net
The evening prior to flight we hold a coordination net to assign the grid information and tactical callsigns. Any last minute information, launch time changes, launch location changes, maybe even a cancellation will be announced on this net.
HF Frequencies
Global Frequencies
Balloon Frequencies
note: The balloon LAN freqs are posted for informational purposes only. This system is accessed via other frequencies and the 2.4 GHz traffic is very weak and intended only to reach from one end of the balloon train to the other. So, ground based receivers won't normally hear this traffic even with substantial gain antennas. A lower frequency LAN is being planned which will operate at greater RF power and offer LAN operations between the balloon and ground controllers.

Future I-Gaters:
EOSS is always in need of I-Gate stations. Check out the EOSS I-Gate page for information on how to participate and why we need you.
Current I-Gate Station:
If you are present at your iGate during the flight try and monitor the tracking and recovery frequency. The ground station likes to check the frequency prior to launch to find out if any stations are out there ready to igate the traffic onto the net for the FAA to monitor.
The prediction program used to determine the track of the balloon prior to flight can now output a prediction for the Rise, Closest Approach, 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.
Your Log Files
Our technical committee members would also request you open a log file and record all the packets you hear and forward onto APRS-IS. Whenever there is a technical failure of a package it is always helpful to have the most complete dataset possible to attempt to determine the cause of failure and possible fixes. After a flight send your data files to me (webmaster) and I will distribute them to the appropriate payload builders. They appreciate these logs even if all goes fine during a flight.
This time out EOSS will have three customers.
note: customers are welcome to submit detailed synopses of their flights or web links to their own web sites.
