Payload Experiment Designer

CU SGC and Metro Gateway

Experimenters are welcome to submit websites for linking or overviews which I will post on a page on the EOSS website.

Internet Gateway Stations:

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.

Tracking and Recovery  

NEWS FROM ALPHA

Don, WA9WWS advises us this is the start of hunting season which means we must be very observant of men with guns. Wear bright clothing if possible, avoid camouflage on this day.

There will be some new hams from CU Boulder and possibly Metro State. Seek them out and congratulate them for their achievement. Let�s make them feel welcome to this fraternity.

Michael Willahan, science instructor from Chatfield HS, will have a payload onboard also. Please welcome him and his associates to our group.

Seek out Chris Koehler and tell him thanks for GSGC support this year.

There will be two flights of 3000 gram balloons. They will be launched within 10 minutes of each other � and will most likely land within 10 minutes of each other. Try to locate landowners early so we can expedite the first recovery and move the students to the second shortly thereafter. After EOSS 157 lands, part of the tracking team will be deployed quickly to recover EOSS 158. Please leave all payloads on the ground until the students can recover them. If it is windy, secure the payload string quickly.

 

Breakfast

• Johnson's Corner (I-25 at exit 254 on the east side of the highway)
  • Google Map
• Arrive: 05:45 to 06:00
• Depart: 06:30

If you want breakfast and to see the happy, early-morning faces, trackers will meet at Johnson�s Corner (I-25 Exit 254, east side) between 06:15 and 06:30.  Plan to leave for the launch site at 7:00 for a 7:40 launch.  Chris Koehler will have bagels and a generous assortment of Halloween leftovers at the launch site as a breakfast alternative.  Trackers also can meet at the launch site or in the predicted landing area.  I will bypass breakfast and go directly to the predicted landing area.
