FASTRAC
Mike, DK3DWN replied to a post I made yesterday on the amsat-bb mailing list. FAST2 seems to be slightly high in frequency, so I updated my scripts last night and captured the following earlier:

FASTRAC
Got up this morning, checked my mheard list and saw an entry I hadn’t seen before for FAST2. Checked my logfiles and I found this (output from listen -t -a):
1200mk: fm FAST2 to BEACON ctl UI pid=F0(Text) len 123 08:20:33
0000 F21001633 38263.461363903952.94 -3773326.54 +4430538.23 +0.00
0040 000 +0.00000 +0.00000+1332283286 016 013 004 006 031.
Wow, I wasn’t expecting a full beacon from one of the two FASTRAC satellites, sure, I recently started listening for them, but still, this was a bit unexpected given that I only have an omni-directional antenna, cool though. Now what does it actually mean?
Well, FAST2 is the Amateur Radio callsign for FASTRAC 2 or “Emma” as the satellite is nicknamed. For the rest, I decided to be lazy, Mike, DK3WN has quite a few telemetry decoder programs written, so I downloaded the one for FASTRAC, put it onto a VM, cleaned up my logfile entry a bit and we get.
More detail on what this means is available here. I was wondering about the date and saw this on their facebook page.
The GPS receiver on Emma has not failed, since separation we have had a harder time of commanding her (can do so at very high elevations for a short time) so at the moment one of the microcontrollers that generates part of the beacon… message needs to be reset, which is why the message shows old information. We are in the process of upgrading our groundstation so that we can more easily command Emma and make sure we can reset that microcontroller.
Thanks for your interest and collaboration,
The FASTRAC Team
By the looks of it, the Atmel AVR is still stuck. Hopefully the command team can get it sorted.
(AX.25) Packets from International Space Station.
Nothing overly complicated. I am capturing the output from the mheard command, part of the Linux AX.25 tools package. The AX.25 port (Radio/TNC/Omnidirectional antenna) is listening for packets from the International Space Station and PCSAT. The output updates every 10 minutes and is available here.
World IPv6 Day
In “Celebration” of World IPv6 Day, David suggested that we try a “Crazy Ping”, showing how easy it is to get IPv6 running, even on the most oddball networks. For the heck of it, I configured up this evening the following
A Netbook with an Icom ID-1 D-Star radio plugged into its ethernet port.
A Laptop with both an Icom ID-1 D-Star radio plugged into its ethernet port, and a Kenwood TH-D72 configured in Kiss Mode (9600baud AX.25) plugged into a USB port. The laptop was then configured with an IPv6 over IPv4 tunnel to…
A Desktop, with a Kenwood TM-D710 configured in Kiss mode plugged into an RS-232 port. The desktop also is my sixxs tunnel endpoint.
It isn’t often that you can ‘hear’ someone connect to your computer, but with every packet, the squelch on the TH-D72 opened. So I could hear every packet going to the notebook.
The “Testbed”:
The result:
j0n@scott:~$ ping6 -c 1 2001:770:132:deaf::2
PING 2001:770:132:deaf::2(2001:770:132:deaf::2) 56 data bytes
64 bytes from 2001:770:132:deaf::2: icmp_seq=1 ttl=60 time=3073 ms
--- 2001:770:132:deaf::2 ping statistics ---
1 packets transmitted, 1 received, 0% packet loss, time 0ms
rtt min/avg/max/mdev = 3073.686/3073.686/3073.686/0.000 ms
Now why would anyone want to run IPv6 over IPv4 over AX.25? well that is a different question altogether, all I can say is that it works, but not very efficiently.
Supporting space missions
I had a very nice surprise waiting for me when I got home today.
Previously, I posted that I played a very small part in receiving data from one of the satellites (Pollux) that formed part of the Atmospheric Neutral Density Expirement on STS-127. Henk, PA3GUO did a nice video about it as well.
Today, the postman delivered an ANDE-2 mission patch which flew on STS-127 (which I also happened to see on the launchpad last June), how cool is that!
IPv6 and aprs.fi
Recently, Hessu, OH7LZB, began the process of migrating his service to IPv6. While he isn’t finished (AAAA still to be added) ipv6.aprs.fi is up and running and usable today.
Ande 2 – The big picture
Excellent video from Henk, PA3GUO showing Amateur Radio’s involvement in the experiment.
Balloon Experiments with Amateur Radio.
Some great High Definition video and information here. Bill Brown, WB8ELK mentioned these guys during his very entertaining speech at the DCC. He is hoping to do a “long duration” flight in the relatively near future, hopefully Amateur Radio Operators at this side of the Atlantic can assist with telemetry reception and even payload recovery.
