RE: CubeSats on same freq!!



Mike,

I didn't put PicPot into the mix. Gosh. Good observation Mike.

If true that's one fine piece of frequency coordination at IARU. I rather
think the sats are not on the same frequencies but instead it's another
example of the lack of up to date information coming from the sat builders.

Appears the launch has go off as planned. Good luck to all sats, especially
those on their own frequency.

Regards...Bill - N6GHZ

Hi Bill,

the same with PicPot and SEEDS (both on 437.485 MHz).
Let's see....

Betreff: [amsat-bb] CubeSats on same freq!!

Hello all,

After reviewing the downlink frequencies again in preparation for the
upcoming launch, I noticed something that has confused me (doesn't take
much) and perhaps some clarifications can be provided.

SACRED and RINCON, both U of Arizona satellites, operate on 436.870 MHz.
That's easier to understand since they can probably command them on or
off.

But nCUBE-1 and ICE Cube-1, from different builders, are on 437.305 MHz.
Frequency misprints (comes from the CubeSat web site)?

IARU's no help. They somehow frequency coordinate but often don't list
frequencies as is the case with these two satellites.

Regards...Bill - N6GHz
