Hi : I guess you could say I miss AO-10 . RS birds AO-40
FO-20 .
I could go on and on.
When I see all the cube sats launched and FM birds I say to
Myself why didn,t they pull all the resources together to
launch
One HEO.
I guess I will have to keep dreaming that this might happen.

IF dreaming season is now open.. :-)
has any amateur satellite mission been conceived (and implemented)
where the satellite is permitted/designed for in-orbit maneuvering
with other spacecraft ? Simple example: Sat A, flies in formation with
Sat B. Complex example: Sat A, changes orbit to rendezvous with Sat B.
Could be useful to avoid debris and other spacecraft, or could be very
useful in "joining" missions with additional tasks as Mission A Sat A
performs operations on/with Mission B Sat B.
concept: "operations" is flexible term: example: fix other spacecraft.
Since these "cubesats" or "microsats" are often launched in clusters,
I would have thought this should be a common topic by now? Any URLs
that describe the maneuvering tasks in-orbit for any class of amateur
spacecraft, please highlight them for education.

Jerry,
A lot of very talented, determined people are working against stiff odds to
actually bring that about. They share the dream, as well as the solder
burns which come with the territory.

If I may add to your maneuvering suggestion Samudra,
--------------
I like to see a selection of deorbiting concepts tried.
This to be done in a manner similar to previous satellites have been
launched from the ISS.
Maybe one launched every other day while the ISS is over head during a
space walk
so TLM and tracking beacons are available for info collection.
As long as the LEO concept is in need of de orbiting and not the HEO bird
it
appears at the rate cube sats are being launched deorbiting will get very
serious shortly.

Don't feel bad, I have the same dream. :-)
My last Satellite contact was on AO-40 with WB6LLO. I just listen now...

Two cubesats, BEVO1 (University of Texas) and AggieSat-2 (Texas A and M
University) deployed earlier this summer were the first phase of developing
this type of rendezvous capability:

http://www.youtube.com/watch?v=FqM3Wq_ijw8
After deployment the two satellites did not separate from each other.

Because we'd likely end up with no LEOs and a HEO still on the ground.

Jerry --
I share your nostalgia, and I've never even been able to work a HEO satellite!
But if you are asking this question in earnest, it has to be said
that even if we amateurs could compell the universities launching
cubesats to do as you ask, the resources would not equal one HEO
launch. Say a cubesat costs $80,000 to launch. If current HEO cost
estimates are correct, and we're looking at over $10,000,000 for that
launch cost, then we would need to harness the wealth of 125 cubesat
teams just for the launch cost. I don't think any university is going
to wait for that.
There is an oft-repeated misapprehension lurking under here, too, and
that is that the wealth going into the cubesat launches is money that
would otherwise be spent on a HEO amateur satellite. Cubesats are (in
large part) university projects aiming to give students access to the
process of designing, launching and controlling a satellite. They are
attractive to granting agencies (and even launch agencies) because of
their eduational potential. To my knowledge, during the design and
launch of previous amateur HEOs, professors did not line up to apply
for grant money to hand over to AMSAT-NA or -DL, as they are now
lining up to apply for money to build cubesats. Contrarywise, I don't
believe many of these cubesats have made any demands at all from the
(hobby) amateur community to defray their costs. (Perhaps this is not
the case in countries where the cubesat represents one of the
country's first forays into space, such as Turkey.)
In short, there is no evidence that cubesat activity is in any way
reducing our opportunities to go to HEO again. Other, currently
overwhelming, factors are doing that all by themselves.
What the cubesat platform has done, though, is offered a regular,
affordable launch opportunity for low LEO. We members of this list
could probably muster enough money to launch our own satellite,
designed here, and controlled by us, if we so wished! (I think at one
point JoAnne tried to start a thread along those lines.) You mention
RS birds: could we deploy a 10m antenna from a 10 cm^3 volume? Maybe
a spooled-out wire? What kind of propulsion can we make to get from
cubesat LEO to something with a better footprint? In my opinion, if we
really are the descendents of the garage-engineers of OSCAR-1, we
should be buying up pumpkin cubesat spaceframes and posting videos for
each other of the cool things we've achieved in that limited, but not
impossible, space.
Here's some other ideas:
1. CW robot (a la RS) in a PIC. Can you do it in a single atmel
atmega328? At 20 MHz? At 4?
2. PIC code so that the bird turns itself off over unpopulated areas.
(I love my solo passes over the Atlantic when I have VO-52 all to
myself, but I'd be willing to give them up for the greater good :-)
Extra credit: have one chip do both of the above under a operating system
3. Antenna testing: hang a cubesat model up 50' in a tree with some
funky antennas on it. Can you make them have the pattern you (we)
want?
4. Propulsion. How much thrust can we safely get into a cube?
4. This one is completly impossible, but boy it would be nice to have
a U/V transponder on a 10 cm^2 board. We'll have to wait years for
someone to do that, though :-)
We really, honestly, still can have fun. Maybe not the fun that some
of you had back in the day, but there's lots of cool stuff to be
undertaken.
Finally, in that spirit, can I encourage everyone to join in on the
cubesat launches in a few days? Watch the launch, get on internet chat
and eavesdrop on the excited conversation of these young people. Join
the global hunt for the proper keplerian elements for these birds, and
copy what telemetry you can. We almost all of us have the skills and
equipment to be part of a remarkable event. I can't tell you the
thrill of letting these people know their baby is alive and beeping in
space.

I just finished up the cables for the rotor
And been reading thru the manual .. ( lacking a bit )
It says 5 minutes intermittent service and something
About 15 minutes rest. I assume then , that it means
5 minutes on , 15 minutes off.
Doesn't seem like it takes a whole 5 minutes to run the whole
Rotation , but wanted to know if its ok to go from one end of
The rotation to the other without stopping? Wanted to ask if that seems
reasonable?
For setup I ran the azimuth and elevation to CCW to the stop to make sure
It stopped correctly and the meter indicated correctly, then went the other
way to full meter deflection, to the
Stop and adjusted the Full Scale adjustment for full scale. That's all
there is
To it? Whats the voltage output adjustments for?
One more thing .. On a side note.. I thought it was cheesey to have "radio
shack"
Type terminal strips on a 600.00 rotor to connect the rotor cable too ...
Why not have a couple connectors there? Even my old Wilson WR-500 had a
connector. Lol
I assume even with 2 small yagis on this rotor, I will now have to guy the
mast due to the
Added weight of the rotor on the mast ?
( better safe then sorry LOL )
Thanks everyone ..

Well said!? I believe any and all satellite endeavors can in the long run be
parlayed into more grandiose efforts.? One thing that has always intrigued
me is the possibility of a "benign" propulsion system for these LEO's.? Our
continued support for these university type efforts can possibly come back
in spades down the road.

I've run mine from end-to-end repeatedly without problems. I would suspect
the duty cycle is also related to the amount of load (antenna size/weight,
and wind) on it, so YMMV.
Looking at the schematic shows the "other" two pots on the back panel have
the same function as the "Full Scale Adj", but instead of driving a meter,
they send the scaled voltage out to the 8-pin DIN connector on the rear
panel, where it is normally goes to the IF232 unit for position feedback.
I don't have a problem with the terminal strips on the back. I made 3'
'pigtails' with spade lugs on them, dressed them neatly into the nylon cable
clamps, and then put some Molex connectors on them. I have the? mating Molex
connectors on my rotor cables in the shack, and this allows me to unplug the
control box and move it around without unscrewing all the terminals.
Total cost about 5 bucks....

I just finished up the cables for the rotor
And been reading thru the manual .. ( lacking a bit )
It says 5 minutes intermittent service and something
About 15 minutes rest.? I assume then , that it means
5 minutes on , 15 minutes off.?
Doesn't seem like it takes a whole 5 minutes to run the whole
Rotation , but wanted to know if its ok to go from one end of
The rotation to the other without stopping? Wanted to ask if that seems
reasonable?
For setup I ran the azimuth and elevation to CCW to the stop to make sure
It stopped correctly and the meter indicated correctly, then went the other
way to full meter deflection, to the
Stop and adjusted the Full Scale adjustment for full scale.? That's all
there is
To it?? Whats the voltage output adjustments for?
One more thing .. On a side note.. I thought it was cheesey to have "radio
shack"
Type terminal strips on a 600.00 rotor to connect the rotor cable too ...
Why not have a couple connectors there? Even my old Wilson WR-500 had a
connector. Lol
I assume even with 2 small yagis on this rotor, I will now have to guy the
mast due to the
Added weight of the rotor on the mast ?
( better safe then sorry LOL )
Thanks everyone ..

I get the feeling that the separator kit is the better way to go .??
I put lugs on the wires for the terminal strip ..
Seems ok ..
