Dear Friends,
There has been a great deal of speculation on the amsat-bb about
the Russian battery on ARISSat-1 having failed. Be aware that this
is nothing other than idle speculation. There has been no
information from RSC-Energia to support this.
I believe the mis-information comes from a report on the ARISSat-1
power system that was written by me and sent to RSC-Energia. One
of the sections included a prediction of the battery life in orbit.
The 825M3 is a Russian space suit battery and its life was not
specified or characterized for operation of a satellite. The most
recent AMSAT Journal includes an article that covers this material.
The article in the AMSAT journal predicts that the 825M3 battery
should last for about 2 months in orbit. That means that if the
satellite was deployed in February as originally planned, it might
be too weak to run the satellite reliably by the time the Yuri
celebration commenced on April 12th. This fact was stated on the
(Russian) Roscosmos web site but is being misinterpreted as the
battery "is weak."
For the record, the battery in ARISSat-1 was a brand new 825M3
space suit battery and was charged on the ISS prior to the February
test. After charging, the battery can run ARISSat-1 for at least 100
hours so it should have had more than enough remaining charge to
operate through the Yuri Gagarin event. It is of course possible
that the battery did indeed fail but any information propagated
on amsat-bb to that effect at this time is not based on facts.
AMSAT is working with RSC-Energia and NASA to identify the actual
reason that the satellite was not heard.

Weather- and Murphy-permitting, I will be in PA State Game Lands 95
tomorrow (FN01bb) and working most of the daytime passes, hopefully
starting with SO-50 at 1345 and going till AO-51 at 2120.
Hope to work you then. I'll post other info on my QRZ.com.

It really does not instill much confidence in partnering with
RSC-Energia for any future satellites. I will withhold judgement of
individuals involved till we learn more. I certainly am not in favor
of spending Amsat funds on such a venture, again.
But then I no longer have a voice in the matter as I have let my
membership in Amsat lapse. That was totally a financial decision -
as a senior retired on social security, I have to chose what I spend
money for. I could continue a couple memberships that provide a
senior/retired rate.
That also means I am retired as a field op.

Hi Tony, AA2TX
I know that you did a great work for ARISSsat-1,congratulations,
but after reading the Gould Smith report AMSAT NEWS SERVICE
ANS-104 ANS Special Bulletin - ARISSat-1 Not Heard During
Gagarin Commemoration everyone understand that there was a poor
connection between NASA, AMSAT and RSC-Energia.
I hope AMSAT will be able to identify the actual technical reason
that the satellite was not heard.
To be honest with you the actual situation of a "unknow technical
reason" for ARISSsat-1 is spiritually similar to when someone forgot
to remove the famous red cap over a valve of AO40 before to fly and
once again we are all concerned for the future !

The ARISSat-1 project can chalk up many successes, here is my list so far:
AMSAT has:
Built and launched a spacecraft which has sent signals back to earth
Grown up significantly in our project management capabilities, now
bearing fruit as AMSAT-Fox is developed
Developed a telemetry scheme that gives us several dB advantage over
anything else previously
flown on an amateur or small university spacecraft
Gown in our understanding of and implementation of ITAR compliance
Learned a fair amount about extracting the most power out of solar
panels and putting it to work or storage
And on a personal level, I have:
Learned a lot about project management -
Learned a lot about BPSK demodulation and channel codecs
Been privileged to work with a lot of smart people

Hi Ed, KL7UW
If you read the Gould Smith report SB SAT @ AMSAT $ANS-104.01
ARISSat-1 Not Heard During Gagarin Commemoration you will realize
that there was a very poor connection between NASA, AMSAT and
RSC-Energia so that any possible responsibility about the unsuccesful
test of ARISSAsat-1 is not only in partnering with the RSC-Energia.

Over a year ago, I flew on a domestic flight to another province. I partly
disassembled my Arrow and put it into my suitcase as it was the easiest way
for me to transport it.
On the trip out, no questions. On the way back, the luggage inspector asked
what it was as it showed up on the scan. He accepted my explanation when I
told him I was a ham. Maybe he was simply curious, but I had my amateur
radio certificate with me just in case I had to give more details.

I have found firsthand that verticals, J poles, and the like work pretty
good on FM satellites. How well do these same antennas work on the SSB
satellites? Would they make VO52 usable? That seems to be the easiest of
the SSB sats to get into. What about FO29?
