TO TMAIL MSWEETING,AMSAT
FROM L. S. Kayser, WA3ZIA
UO11 finally heard in Ottawa!!!!!
at 1425 to 1436 Z this date UO11 was copied by VE3BNO in Ottawa.
Congratulations all, we will start now collecting Telem
regularly. It has been worth the wait!
Surrey note please PRIME link wont be bsck until I return to work
around june 1.

Subj: Oscar-11
The following report was circulated within the G.B; it is
the only output we are likely to generate for a few hours.
The telemetry received so far appears very good.
Following persistent commanding from the Guildford command
station, the University of Surrey's second spacecraft,
UoSAT-Oscar-11 (UoSAT-2) is now transmitting telemetry data
after weeks of silence.
Over the weekend of 11th to 13th May, dedicated radio
amateurs at Stanford Research International in California
and their outpost in Greenland heard very weak signals
emanating from the satellite command RECEIVERS which, by
their nature of operation, generate small signals on a
frequency near to that which they normally listen. These
signals told the University satellite team that their craft
was still alive, although at this time the chances of complete
recovery were not known. Although this observation, the
first one confirmed since launch, did not lead directly to
recovering the satellite, it did confirm that the orbital
predictions provided by the NASA tracking organisations
were correct and that the object being tracked by the Surrey
team was indeed UoSAT-2.
This morning (14th May) at 10:24 GMT, with Dr. Martin
Sweeting (UoSAT project manager) abroad on holiday, Neville
Bean and Roger Peel, full time satellite researchers in the
Department of Electronic and Electrical Engineering
continued to command the satellite using its 144MHz uplink,
to no effect. At 11:01GMT (12:01 BST), Neville made
further command attempts on 438MHz, and after a brief
stream of initialisation commands, the main UoSAT-2 beacon
(145.825MHz) was powered up at 11:05.
The signals from the spacecraft were as strong as the last
ones heard from it on the 1st March, when it stopped
transmitting shortly after launch. Telemetry data, from the
initial two orbital passes over Guildford, appears to be
very encouraging, with temperatures around -5 to 0 degrees
centigrade, as expected, and a battery voltage of 14.6
volts. The spacecraft is still spinning, but this will have
stabilised since the previous data received immediately
after launch, ready for attitude control manoeuvres. These
will not start until after the causes of the 11 week
silence have been investigated, a process that itself may take
many weeks in order to exercise the caution necessary in
this situation.
The UoSAT-2 spacecraft will be transmitting telemetry data
continuously for the next few days while initial checks are
made on the telecommand system, but after this other data
formats will be generated using the spacecraft computer to
check further the spacecraft's health.
Initially, the University of Surrey is encouraging radio
amateurs and schools used to collecting data from
UoSAT-1 to send them all the telemetry they receive from
UoSAT-2, so that the picture of its current state can be
generated as soon as possible. The AMSAT series of
amateur-radio oriented satellites benefit greatly from the
thousands of receiving stations around the world who are able
to send such data back to the controlling organisation.

First UO-11 Telem Frames at KA9Q
Here are the first two frames that were solidly recieved at KA9Q
on the first pass this morning. A decoded version of these same
frames is on the 'eng' bb. I've got tons more of this stuff.
Enjoy!

The program echoes each raw format line, then follows it with the
interpretation. Note that the clock was running, but it had not
been intialized.

C-language UO-11 decoder fix
For those of you using my C-language telemetry decoding program for
UO-11, I've discovered two minor bugs:
Change the line which reads
if(sscanf(cp,"UOSAT-2%2d%2d%2d%1d%2d%2d%2d",&year,&month,&day,
to
if(sscanf(cp,"\036UOSAT-2%2d%2d%2d%1d%2d%2d%2d",&year,&month,&day,
Since I had never received telemtry direct before, I didn't know about
the leading "funny character" which the various electronic mail systems
had stripped off.
Also change the line which reads
n = sscanf(cp,"%1d%1d%1d%1d%1d%1x",&chan1,&chan0,&n2,&n1,&n0,&chk);
to
n = sscanf(cp,"%1d%1d%1x%1x%1x%1x",&chan1,&chan0,&n2,&n1,&n0,&chk);
I didn't notice that hex digits were valid in the status bit channels
of the telemetry (those greater than 60.) In particular, this kept channels
61 and 66 from decoding.
73, Phil

UO11 finally heard in Ottawa!!!!!
at 1425 to 1436 Z this date UO11 was copied by VE3BNO in Ottawa.
Congratulations all, we will start now collecting Telem
regularly. It has been worth the wait!
Surrey note please PRIME link wont be bsck until I return to work
around june 1.

The following report was circulated within the G.B; it is
the only output we are likely to generate for a few hours.
The telemetry received so far appears very good.
Following persistent commanding from the Guildford command
station, the University of Surrey's second spacecraft,
UoSAT-Oscar-11 (UoSAT-2) is now transmitting telemetry data
after weeks of silence.
Over the weekend of 11th to 13th May, dedicated radio
amateurs at Stanford Research International in California
and their outpost in Greenland heard very weak signals
emanating from the satellite command RECEIVERS which, by
their nature of operation, generate small signals on a
frequency near to that which they normally listen. These
signals told the University satellite team that their craft
was still alive, although at this time the chances of complete
recovery were not known. Although this observation, the
first one confirmed since launch, did not lead directly to
recovering the satellite, it did confirm that the orbital
predictions provided by the NASA tracking organisations
were correct and that the object being tracked by the Surrey
team was indeed UoSAT-2.
This morning (14th May) at 10:24 GMT, with Dr. Martin
Sweeting (UoSAT project manager) abroad on holiday, Neville
Bean and Roger Peel, full time satellite researchers in the
Department of Electronic and Electrical Engineering
continued to command the satellite using its 144MHz uplink,
to no effect. At 11:01GMT (12:01 BST), Neville made
further command attempts on 438MHz, and after a brief
stream of initialisation commands, the main UoSAT-2 beacon
(145.825MHz) was powered up at 11:05.
The signals from the spacecraft were as strong as the last
ones heard from it on the 1st March, when it stopped
transmitting shortly after launch. Telemetry data, from the
initial two orbital passes over Guildford, appears to be
very encouraging, with temperatures around -5 to 0 degrees
centigrade, as expected, and a battery voltage of 14.6
volts. The spacecraft is still spinning, but this will have
stabilised since the previous data received immediately
after launch, ready for attitude control manoeuvres. These
will not start until after the causes of the 11 week
silence have been investigated, a process that itself may take
many weeks in order to exercise the caution necessary in
this situation.
The UoSAT-2 spacecraft will be transmitting telemetry data
continuously for the next few days while initial checks are
made on the telecommand system, but after this other data
formats will be generated using the spacecraft computer to
check further the spacecraft's health.
Initially, the University of Surrey is encouraging radio
amateurs and schools used to collecting data from
UoSAT-1 to send them all the telemetry they receive from
UoSAT-2, so that the picture of its current state can be
generated as soon as possible. The AMSAT series of
amateur-radio oriented satellites benefit greatly from the
thousands of receiving stations around the world who are able
to send such data back to the controlling organisation.
