Es'hail mind storm. !! A CubeSat Converter !!!


Subject [amsat-bb] Es'hail  mind storm. !!

Es?hail-2 geostationary satellite carrying AmateurRadio transponders expected to launch November 15 - 2018/11/05/
Most of the operators have no gears to covering the new frequencies.
So is it possible to put a down-converter and up-converter in one of the cubesat ??
Also the foot print will extend tremendously as the cubesat cover new distance far from all Es?hail fixed footprint ?!
Anyone?s can use V/U gears tracking the cubesat ,which really the signal from Es?hail sat!!
Again it?s a mind storm idea.
I Hope others will share with more ideas and info !!

Hi,
Interesting idea.
Problems to overcome:
Size of dish / patch required to be flown as part of satellite
Attitude control and pointing in real time
Power management
Band width limitations
Doppler correction
Frequency stabilty

Any more folks?

Hi Dave, Nader,

A CubeSat Converter is certainly an interesting thought.? In addition to
the challenges (that's the hip cop-out from saying "problem" these days)
that you noted, I'm thinking that the ConverterSat would also:

Have to be in the footprint of Es'hail
So as a converter even only in the footprint for stations in the
footprint but w/o the S and X equipment, it would only offer a 10-20
minute window to Es'hail the usual 3-6 times per day
In trying to extend the footprint, it would need to be of a pretty high
altitude itself in order to extend the footprint by much
Being on the edge of the Es'hail footprint in order to extend it,
requires more power/gain/pointing to connect with Es'hail

But I guess these are more "usefulness" challenges than the RF
challenges of acting as the converter you have listed.
It gave me thoughts about GOLF-TEE trying to bridge the gap, but would
have design implications as you noted that at least wouldn't be possible
in our current timeline.

I would make more sense to me, in my humble unbiased opinion,
to have someone in the footprint of Es'hail to put together
a ground station that that is also an EchoLink node. That
way, anyone in the world could potentially access Es'hail
via EchoLink.? It would be an interesting exercise, anyway.

Hey Mac,

I like that very much! Let's do a SatNogs reverse. One or more station
within the footprint that folks around the world can use to connect to
Eshail.

What would it cost to put together a ground station?
Perhaps a little crowd sourcing (cash/hardware) could
get one built and dedicated to the task.
