Note to self ,
I forgot to ask ,
" We are planning to use the HAM frequency(ies) to send data down from the cubesat to earth "
What makes you think as a non ham , you can - do that ?
Oh dang , its been said .
When first satellite was put in orbit question of legality of overflying sovereign territory was soon brought up - by lawyers ($) of course.
Publishing images of such territories when satellites grew up and got smarter could be also debatable.
What makes an average 2 meters HT user think that a (private) satellite TX FREQUENCY is under anybody jurisdiction?
Or to put the subject in a different / direct perspective - can FCC interfere with launching a private satellite using ANY frequency?
And I am sorry for OT.
Back to the subject.
There are HUGE antenna arrays listening to the Universe radio waves.
As far as I know they have not heard / found single intelligent transmission.
What makes this group think that they can do better?
I am sure there is an advanced intelligent life out there. While drawing parallel with recent years of our similarly highly advanced usage of amateur radio on this planet, there are two possibilities when we intercept their transmissions - repeater kerchinks (sic?) or "59 QSL".
^^^What they said^^^
SETI = Silly Effort To Investigate. - Stanton Friedman
Cubesats are becoming like repeaters were in the 1970s and early 1980s - everybody, it seems, had one because they could.
Why don't you try to get the ARRL interested in this effort? Seems to me they'd love to have their name on it simply for the public relations aspect.
Bingo! Put this in stone.
Good point Fred.
I just realized that this thread was started end of January and Mr Cote never returned after making his first post.
So basically, it's a spam thread.
Don't expect him to respond.... Probably ran off with the money.
Or another alien abduction....
To address the question you pose, I take it you have never heard of the ITU?
Early on in the nascent space program the major players, interested parties and, ultimately, the membership of the United Nations, recognized the shear chaos that would soon come about if every space faring country simply did whatever they wished to do in space without proper coordination with other nation's space programs. Friends and Foes alike could see the harm that would come about if multiple nations tried to park their new satellites in orbits that necessarily intersected one another, occupied the same point n space, or chose to use identical, or nearly identical, radio frequencies for different satellites that are otherwise grouped close together in terms of line of site from earth stations. This would benefit nobody whatsoever and so they drafted and adopted treaties authorizing the creation of groups responsible for coordinating all the nation's satellites and spacecraft so that all may coexist as effectively as possible with minimum unnecessary interference to one another's programs. Insofar as radio spectrum allocations go, that coordination task was assigned to the ITU, the same body responsible for coordinating RF spectrum internationally.
Additionally, as an intentional transmitter both the nations in which the satellite is constructed and launched would have jurisdiction over the satellite prior to launch and, by treaty, the nation that owns the satellite is liable for any and all liabilities associated with the launch and use of the satellite, so that brings in responsible earthbound parties as well. Plus some nation somewhere is going to need to issue it a proper callsign if use of the satellite on amateur frequencies is to be legal anywhere as amateurs are only permitted, in most nations at least, to communicate with other properly licensed amateurs. Here in the U.S., at least, an amateur can be fined for engaging in a QSO with an obviously unlicensed (forged, pirated, etc.) party once such status becomes known or should be known (e.g. party fails or tefuses to properly identify within the required 5-10 minute window). I would imagine many other nations have similar rules on their books as well with respect to communications with unlicensed/pirate stations. And, of course, if the satellite is listening for commands on a frequency in the AR band then only a licensed amateur may communicate with it and legally transmit on those frequencies, but it still needs a proper callsign from someone. A non amateur transmitting on those frequencies will likely be violating the laws of whatever nation they are operating from unless they have secured special regulatory permission to do otherwise.
Not truly off topic... especially since the poster has spambandoned this post.
If he thinks his group can use amateur frequencies without permission, then we can use his thread without permission!
And your question is a good one, well answered by Ethan (thanks!).
