Payload Configuration:
E-B-B-B-E (Earth, Balloon, Balloon, Balloon, Earth)
The possibility of a packet connection through three balloon will be possible
this flight.
Start looking for
contacts when the closest balloon you can hear direct reaches around 50K feet.
ALSO, please allow plenty of time and packet space for the ground stations to
attempt their EBBBE contacts FIRST.
Once we have a verified EBBE contact, general contacts through the balloons
will be welcome. However, if traffic gets too busy the control operators of each
balloon may request a cessation of contact attempts to ensure that a smooth
uninterrupted flow of tracking data can still be received on the ground. The
tracking functions are the PRIME use on each balloon and we don't want to lose
track of our payload positions due to heavy human generated packet traffic.
The Aliases of the balloons are:
- EOSS = EOSS
- NSTAR = NSTAR
- ORB = ORB
The TNC Callsigns are:
- EOSS=W5VSI-11
- NSTAR = N9XTN-11
- ORB = KC5TRB-11
The Ground Station Callsigns are:
- EOSS = W5VSI-1
- NSTAR = N9XTN-9
- ORB = ?
The Frequency is 144.340 MHz.
