EOSS Frequencies:

Global Frequencies

• Preflight Net:
  • 147.225 MHz 107.2 Hz tone
• Tracking and Recovery Operations
  • 449.450 MHz RMRL Repeater(103.5 Hz Tone)
  • 146.550 MHz simplex (same simplex for field and launch ops)
  • Repeater Coverage Pages - Listings of all repeaters available in the expected flight areas.
  • There may be FRS operations on channel 8. See THIS PAGE for a list of channel numbers and their associated UHF Frequencies.
  • 7.228 MHz HF (sporadic usage)
• HF Net
  • 7.228 MHz
    • The HF net may or may not be in operation for any particular flight. It depends on whether or not we get a volunteer net control station.
    • This net will move UP (away from Advanced and Extra band slices) to accommodate QRM. It should not set up above 7.250 MHz so if you don't hear it in that slice of spectrum, it is probably inactive. However station to station traffic for the Tracking and Recovery guys might pop up.

Internet Gateway Stations:

Future I-Gaters:

Check out the EOSS I-Gate page for information on how to participate and why we need you.

Current I-Gate Station:

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, 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.

Tracking and Recovery Info:

Help us build a database of the best RDF/Observation sites in Eastern Colorado. See the Observation Site Database page for ideas on what we'd like to see in this DB and if you're interested in the Balloon Track use of that database

Our Customer

• CU Gateways Balloon Sats
• C-SMARTS

note: customers are welcome to submit detailed synopses of their flights or web links to their own web sites.

Radio Coverage:

• Green, you should be able to work the payload systems.

• Red, is the border of the received signal. Red appears jittery because it is depicted topographically. Thus, the red dots on the eastern half of the map but well within the maximum distance show hilly terrain behind (east) which reception is not possible.

This is a generic 95,000 ft ASL coverage map for flights that depart from the vicinity of Windsor, Colorado. Flight day coverage may vary depending on upper air winds.
