Flight Announcement for EOSS-191/192

Flight Coordinator: Jim Langsted, KC0PRS  

LAUNCH DATE: November 16th, 2013 (wx delay +1 day)
LAUNCH TIME

• EOSS-191 - 06:50 am MST (23:50 UTC)
• EOSS-192 - 07:10 am MST (14:10 UTC)

LAUNCH SITE: Windsor, CO (Driving Directions to Windsor Launch Site)

EOSS Flight Day Frequencies:

Tracking and Recovery Frequencies

Preflight Net:

• 147.225 MHz (107.2 HZ Tone) CRA Repeater, 8 pm MDT preceding night 
• 146.940 MHz (103.5 HZ Tone) RMRL Repeater if the CRA machine is down
• 146.640 MHz will serve as a backup frequency

Tracking and Recovery Operations  

• Front Range and out east 
  • 449.450 MHz RMRL (103.5 Hz Tone) 
  • 145.295 MHz (100.0 Hz Tone) 
• Field Simplex Frequencies   
  • 446.100 MHz simplex for eoss-191 field recovery operations
  • 446.150 MHz simplex for eoss-192 
  • Note: Some radios insist on incorrectly placing a negative 5 MHz offset when selecting frequencies from the simplex portion of the 70 CM band. Check your radio and if this is the case. Consider programming in this simplex frequency to a memory channel as some radios have demonstrated the annoying habit of re-inserting the offset if you momentarily shift to a repeater then return to the simplex freq. Check the operation of your radio on this simplex freq to be ready for however your radio behaves.
  • 146.550 MHz Backup field simplex

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 Operations

Hello Trackers!

We will be launching two heavies for Colorado Space Grant (CSG) on Saturday Morning, 11/16 with a weather date of 11/17.  If we need to fly 11/17, Chris, KB0YRZ will be our Alpha.  It appears this will be a long set of flights heading towards Sterling, Colorado, so we may need to get an early start so we can be closer to the prediction by 7:00.  As a reminder, at the recovery site, be sure to meet and greet the students and learn about their experiments.  They appreciate our interest and it is fun to rub shoulders with our nation�s future. 

We may need to hilltop the 449.450 repeater to reach the ground station operators.  I will take the responsibility to straddle the Sterling repeater and the RMRL repeater as best I can. 

Here�s the scoop.  Please advise Rick (for the Web site updates) and me of any omissions or corrections.

Breakfast:

For breakfast, we can convene at the McDonalds in Ft Morgan at 5:45.  Post-flight meal can be determined by the EOSS Food and Beverage Coordinator, Parker Meer.
