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 

From Last Flight. New info posted the day prior to flight,

Quick Links are a new method being used to connect payloads together on the flight string. SEE THIS PAGE on instructions on how to properly open them upon recovery enabling easy transport of shorter lengths of the payload train.

Breakfast

  • McDonalds at Limon (I-70 exit 359 south side)

  • 06:00 MST

  • Need to depart to the field no later than 06:30.

Future Flight Schedule

as of January 16th, 2010

All dates and launch locations should be considered tentative. The WX delay date is indicated by a "plus" x days indicator i.e. +1 means a one day delay is available +7 a one week delay is available. An "n" indicates no available WX delay date.

Tentative in fuchsia
Recently updated in Red

Flight numbers are always in a state of flux and so are not highlighted as being changed

by ChangeDetection

Enter your email address above and you will receive notifications from the ChangeDetection.com website whenever this page is altered. Instead of entering your email you can visit the site and read all their privacy info if you wish. Just copy the URL to this page so that, if you decide to get alerts, you can paste it into their forms at ChangeDetection.com. Or, if you decide you trust them, you can just return here and enter your email address.

Be ADVISED, this page sometimes goes through multiple edits in a single day when initially prepared and when we close in on launch day, I'm usually informed of any changes and updates that need to be made. So, you can expect to get a fair number of alerts. Each alert comes with an unsubscribe. So, if you get tired of being bombarded, stop the monitor.


The tag for recently edited information will remain in place for a minimum of 24 hours. After that period the tag will remain in place until new updates to the page are made. When the new updates are added, the tags will be moved to indicate that new information.

The tag will not be removed if there are no other changes to be made to the page. This will avoid somewhat misleading ChangeDetection notifications (above) regarding the state of this page.
