Kind of agree Bill-it is analogous to the older AO-7 on line log, where the
qso rate was tabulated. I'm sure none of us paid any attention to that. I
think I got up to the 7 or 8 position. We're competitive creatures.

Hi,
It took 40 minutes to write the code of the train on the way to work
this morning and was
an interesting challenge and the Google Analytics spiked as soon as I
released and and announced it.
So I'm happy with it, as are the the FUNcube team. One of those asking
for it, is part of the team.

The Upload Ranking page is nicely done. I personally use it to look

Content-Type: text/plain; charset=ISO-8859-1
Need an AMSAT greybeard with attitude control experience.
We want to use only one magnetorguer coil (a Z coil) to more or less keep
our Z axis aligned with the Earth's axis (+/-30 deg)
We figure if we energize the Z coil only twice per orbit while over the
equator where the Earth's magnetic field is aligned with the poles we can
eventually bring it into alignment. Then we maintain that alignment using
white/black differential solar radiation pressure to maintain a fractional
RPM about the Z axis.
I need help from some greybeards to prove this is possible.

#22 likes it. I think it'd be neat to compare the rankings to latitude as
well. My station has run almost full time collecting telemetry since launch,
and I continue to slide down the list. I'm not upset or even bothered by it,
but it illustrates how much more access time a high latitude station gets on
a polar orbit as compared to say, a 28.3 degree latitude location.
Competition has probably doubled the participation in this endeavor, which
only helps the project. Plus, if it doesn't hurt anyone, why even care? Much
better things to get tweaked about.

Bob,
I am not a rocket scientist but may qualify as a greybeard.
Have been an ardent follower of satellite attitudes for many years.
I would have thought that passive magnetic stabilisation would have been the
preferred option to meet your objective.
In principle your idea should work, however you would need some smart
processing on board as the Earth's Main Field inclination does not follow
the equator.
The only concern I would envisage is that if the magnetic coil is not
triggered precisely relative to the earth's magnetic field you may flip the
satellite and negate your objective.
Eastern Hemisphere passes should not present a timing issue but the Western
Hemisphere (over the Americas) may present a real timing issue thus
processing+++.
Just my two bobs worth.

Colin VK5HI.

The $50sat team is celebrating 90 days in orbit by proposing a technical
challenge to all interested amateurs. $50sat is capable of responding to
uplink command packets:
There are 3 open packets: Test packet - $50SAT responds by sending the RSSI
of the received packet in slow FM Morse. Request data packet - the normal
data packet is sent. Request RTTY - The RTTY is sent. In addition all
received packets result in two copies of the ack packet being sent, that
contains the RSSI of the received packet.
All the required information to accomplish this is available on the drop box
location available through the $50sat web page at www.50dollarsat.info .
Anyone that can demonstrate a successful command uplink by submitting a
recording of the response packet along with the date, time and location of
of the contact will receive aCertificate of Technical Accomplishment signed
by all three builders of $50sat. Submissions can be madeto the $50sat email
address; 50dollarsat at yahoo.com. This is a significant challenge because
there is no magic black box that you can buy to do this.
After 90 days of operation, the Kodak KLIC-7002 camera battery that powers
the satellite has fallen off about 100mV, but operations still seem normal.
We have also programmed a special 5th morse beacon to thank our launch
sponsor and mentor prof. Bob Twiggs. Please give a listen for the message
TNX KE6QMD on the FM Morse beacon.
QSL cards are still available to anyone that posts telemetry, either hand
copied CW or RTTY captures, to the 50dollarsat yahoo group.
73 and good luck to all from the $50sat team

challenge to all interested amateurs. $50sat is capable of responding to
uplink command packets:
>There are 3 open packets: Test packet - $50SAT responds by sending the RSSI
of the received packet in slow FM Morse. Request data packet - the normal
data packet is sent. Request RTTY - The RTTY is sent. In addition all
received packets result in two copies of the ack packet being sent, that
contains the RSSI of the received packet.
>All the required information to accomplish this is available on the drop
box location available through the $50sat web page at www.50dollarsat.info .
>Anyone that can demonstrate a successful command uplink by submitting a
recording of the response packet along with the date, time and location of
of the contact will receive aCertificate of Technical Accomplishment signed
by all three builders of $50sat.? Submissions can be madeto the $50sat email
address; 50dollarsat at yahoo.com.? This is a significant challenge because
there is no magic black box that you can buy to do this.
>After 90 days of operation, the Kodak KLIC-7002 camera battery that powers
the satellite has fallen off about 100mV, but operations still seem normal.
>We have also programmed a special 5th morse beacon to thank our launch
sponsor and mentor prof. Bob Twiggs. Please give a listen for? the message
TNX KE6QMD on the FM Morse beacon.
>QSL cards are still available to anyone that posts telemetry, either hand
copied CW or RTTY captures, to the 50dollarsat yahoo group.
>73 and good luck to all from the $50sat team
