Re: Yes - FUNcube IS Fun!

I have to check the FUNcube data - but it is possible that it was just transmitting 30mW on this pass ... Which makes this little experiment all the MORE incredible: Hearing a 30mW signal from a bird no closer than about 450 miles - what a GREAT "line of sight" experiment for ANY classroom!

The YouTube description reads: Satellites in Low Earth Orbit have tons of nifty signals, but they move quickly though the sky and are difficult to track with fine accuracy. This lecture describes a remotely operable satellite tracking system that the author built from a Navy-surplus Inmarsat dish in Southern Appalachia. The entire system is controlled through a Postgres database, fed by various daemons spread across multiple machines. So when I click on a satellite on my laptop or cellphone, it runs “UPDATE target SET name=’Voyager 1?;” and the motor daemon then begins to track the new target while the prediction daemon maintains accurate estimates of its position in the sky. Additional daemons take spectral prints or software-defined radio recordings of the targeted object for later review. There is a description of the system on Travis Goodspeed’s Blog at http://travisgoodspeed.blogspot.co.uk/ Other 30c3 videos available at http://www.youtube.com/user/albertveli/videos 30th Chaos Computer Congress https://events.ccc.de/congress/2013/wiki/Main_Page [ANS thanks AMSAT-UK for the above announcement] --------------------------------------------------------------------- High Resolution Data available on FUNcube Data Warehouse As promised, we are making the FUNcube-1 (AO-73) CubeSat High Resolution Data available for download from the Data Warehouse.

VQ9, CHAGOS (Update). Last week we reported that Jim, ND9M, is once again active as VQ9JC from Diego Garcia. Jim informed OPDX that he arrived on the island a month ago, but he had to get his license renewed; it expired a couple days before he landed. Jim states, "Normally, I get it renewed within one business day, but this time there was an administrative hiccup that led to a month- long delay. The British military officer in charge of the island - called the 'Brit Rep' - was new to his post here. He read all the can's and cannot's of the job, and the legal info about issuing ham licenses says that tickets are signed by the Territorial Commissioner who's back in the U.K. The Brit Rep finally got the official word last week that issuing authority was delegated to the local office, and my license was signed the next day. This was the first time in the 15 years I've been coming here that anything like that had happened. In fact, licensing had been so smooth here that in 2008, I walked in to the Brit Rep's office without an appointment and left 45 minutes later with not only a signed renewal for my regular VQ9JC license but also a special temporary license for my VQ98JC operation. I wonder if anyone else can claim receiving two licenses fully authorized with- out previous notice that fast! Anyway, I'm still operating Field Day style from the covered picnic table at the park which has AC power and dozens of gecko lizards chasing the bugs. The table is about 30 feet from the wall of the jungle, and this weekend I'll try to thread a 135-foot OCF dipole through all the trees in the jungle so that I can not only leave the antenna up but also have multi-band capability. If I hoist the antenna where it can be seen, I would stand a very good chance of it being quickly removed as the 150 pound fishing line that I use to secure the antenna and the copper wire are both precious commo- dities here. The OCF dipole doesn't work on 15m, 30m, or 60m, even with a match- box, so I'll put up separate dipoles for 15 and 30 and feed those two and the OCF to a switch. I don't know yet if I'll put up a 60m dipole. The 80m OCF is going to be a big enough project just to get it hoisted to only 25 feet; the jungle's pretty thick! I'll also be putting up a 20m dipole and maybe a 30m dipole as well on the ship. Obviously, I sign /MM during any contacts made from the ship as I did earlier this year. Contacts with me as /MM aren't valid for DXCC of course, but SKCC ops can count them if my ship's QTH is near the island. The rig is an FT-857D. I'll be running 100 watts most of the time, but I'm expecting to do some QRP work from here too. Most of my oper- ating will be CW as usual (with a cootie most times), but I'll be on SSB occasionally. Also, I'm a rookie when it comes to digital comms, but I'm hoping to get my Rigblaster and FLDigi software configured to do some PSK and RTTY work. While on board the ship, I use an Icom IC-760 that I have set up in my service shop. I feed the coax through a helicopter control center that's directly above my shop. My shipboard antennas are about 115 feet above the water line. I don't have internet connectivity when I'm at my operating QTH on the island, so I obviously can't help with real-time QSY requests or the ever present 'EU PSE' when I'm calling for NA & SA stations." OPDX asked Jim about the status of the club station, possibly using a special VQ prefix for 2014, activity on the satellites and if he would attend the 2014 Dayton HamVention, and he replied, "Yeah, the ham club station is gone forever unfortunately. The log periodic has been grounded and dismantled, and everything in the shack has been turned back over to the Navy. I'm here six months out of the year of course, but once Larry, VQ9LA left three years ago, there was no one reliably present during my off times. When the Navy's MWR office personnel made a routine visit, they found nobody there since I was Stateside, so they decided that the club was no longer in use and took what they thought were appropriate steps. By the time I got back to the island and worked my way up the chain of command, the deal had been sealed. And yes, I'm working the satellites out here although there aren't many ops to work. I'll be on the birds when I get home again next year. I don't know yet if my XYL Cori (KK4CGA) and I will be at Dayton this coming May or not. We're hoping to go to New England for the ARRL Centennial in July, and we'll likely do only one trip. My assignment schedule has me returning to the ship a few days before the national convention, and I'm trying to work things out with the guy that's here when I'm off ship for him to stay a little longer so that I can attend. He hasn't given me a firm answer yet though. My plan for 2014 is to get VQ94JC issued for sometime during the second half of the year. The local licensing office has no require- ments toward my getting a ticket other than having one already issued by the FCC. My US license expires in April, and the FCC won't enable the renewing process until 90 days before the expir- ation date, so I have to wait until early January to do that. If I can get the renewed license here - actually just a scanned copy will do and my XYL will send that - I can turn that over to the local office, and they should issue me the short-term ticket. Emphasis on special. It's all legal of course, but the folks in that office are all British military who typically do one-year tours here before being re-assigned, so I can never assume that the next person will cooperate. I'm optimistic though as I've already had 7 VQ9xJC licenses plus the VQ975FOC ticket earlier this year, so the precedent's pretty well established. When I started doing the VQ9xJC bit in 2007, I did it just for fun and I thought the WPX chasers would like it. I really didn't expect to still be doing it after so many years. Now I'm looking ahead at rounding out the decade of annual special callsigns and thinking about what special prefix variation to initiate after the 10th one!" QSL via ND9M.

The event is scheduled to begin at approximately 10:43 UTC. The duration of the contact is approximately 9 minutes and 30 seconds. The contact will be direct between OR4ISS and SP3POW. The contact should be audible over Poland and adjacent areas. Interested parties are invited to listen in on the 145.80 MHz downlink. The contact is expected to be conducted in English. The Centre of Technical Schools in Ostrew Wielkopolski is a school which educates future electronics and mechatronics engineers, computer scientists and renewable energy specialists. Our school has been cooperating with Polish universities, electronic and mechatronic industrial plants and schools in Germany and the UK, what brings very good results. Thanks to the participation in the ARISS program our school has partnered with the Space Research Centre of the Polish Academy of Sciences in Warsaw. Our students participate in various forms of extra-curricular activities which develop their passions and interests. As a result, they have created many interesting electronic and mechatronic devices. For example, some of the recent constructions include fpv plane, a qudrocopter, a stratospheric balloon capsule, some amateur radio equipment and many more. Currently, the school has 800 students aged 16 - 19 years. The Center of Technical Schools has invited its younger mates (students 13 - 15 years old) from Junior High School No. 1 named of Polish Nobel laureates in Ostr?w Wielkopolski and 10 - 12 year-old students from Pope John Paul II Primary School in Lamki so that they all can participate in the ARISS program. Preparations for the ARISS contact began in late 2011. A series of amateur radio classes were carried out so that students could learn the rules of work on the radio. It was a very interesting experience to carry out radio communications through amateur radio satellites and to take photos from NOAA satellites. In addition, we monitored other radio signals from the space. Most emotions were from the radio contact with the ISS in the APRS system and from listening to ARISS contacts of other schools in Poland and Europe. The schools participating in the ARISS program organized a series of events to promote various fields of science, particularly those that are the most relevant for the development of astronautics. Participants will ask as many of the following questions as time allows: 1. What scientific experiments are carried out on the space station at present? 2. How does the magnetic needle work in space? 3. How do you handle different illnesses? 4. How would a pendulum clock work on board of the ISS? 5. Was there anything that surprised or impressed you during your stay in space? 6. What was the largest mammal (except for humans) which was on the ISS? 7. How do flying insects behave in zero gravity? 8. Do you know how many centimeters your body lengthened in weightlessness? 9. Is it easy to use a pen or a fountain pen on the space station? 10. Do you think that time in space passes faster? 11. How do you observe and explore the Moon? 12. What or how did you feel when you saw the Earth from space for the first time? 13. Does Kirobo work well and fulfill its mission on the ISS? 14. Is it hard to get used to weightlessness? 15. Is it possible to be able to breed crystals in weightlessness?

We will command the ballon to inflate 90 days into the mission. Most CubeSats are far too small to see from the ground, but SkyCube will be an exception. The satellite will carry a tightly-packed balloon, made of 0.35-mil (9 µm) low-density polyethylene, coated with highly reflective titanium dioxide (TiO2) powder. During the final phase of the mission, the balloon will be inflated with a 4- gram CO2 cartridge, and expand to a diameter of nearly 7 feet (2 m). This will make SkyCube brightly visible to millions of people on the ground as it passes over the Earth's twilight regions. SkyCube's balloon serves another purpose. Once it inflates, SkyCube's orbit will decay rapidly due to atmospheric drag. Less than two weeks after balloon inflation, SkyCube will re-enter the Earth's atmosphere and burn up harmlessly. The balloon lets SkyCube end its mission cleanly, and avoid becoming space debris that could harmfully impact future missions. SkyCube's balloon was developed by Global Western, an experienced supplier of aerostats for NASA, JPL, and others with unique high-altitude ballooning needs. Further details are available in SkyCube's Orbital Debris Assesment Report (ODAR), required by NASA and approved with our FCC license, above.

FUNcube telemetry performance?
by Mark Spencer 19 Apr '14

19 Apr '14

Phil, I have been monitoring the FC telemetry pretty closely and have some observations for what it is worth: 1. The last update to the Dashboard produced marked improvement in decoding the telemetry. 2. Using an IC910, M^2 14-element RHCP yagi with antenna mounted preamp, I typically decode around 120 frames and lose around 10 frames. 3. Using the FCD with a simple turn-style RHCP with antenna mounted preamp, I will get approximately one third the performance of the main station setup. Using a simple antenna with no preamp I get dismal performance with the FCD. 4. Of course I have more success decoding the telemetry when the bird is in the daylight mode than when operating in the night/transponder mode. 5. I have not noticed any significant fading of the signal with the M^2 setup except some minor fading at AOS/LOS. I will get fading using the turn-style however the fades appear to be due to the nulls in that antenna pattern more than due to fades from the satellite. However, the reduced signal strength helps to emphasize the fades with the turn-style. 6. I estimate that it takes a minimum of 50 decoded frames to capture a full set of whole orbit data. It requires a significant number of additional frames to capture usable high resolution data during a pass (I define a usable data set as being able to determine the rotation rate of the satellite from the high resolution data). 7. There is significant frequency drift in the downlink frequency that tracks the temperature of the satellite internals. I also notice significant FMing of the downlink frequency when the transponder is being used (appears to track with the power used by the transponder). The Dashboard does a pretty good job of compensating for these frequency deviations, I haven't noticed any significant loss of data due to this FMing. The frequency drifting needs some attention when using a traditional rig under computer control (the drift is beyond Doppler). When using the FCD, the Dashboard takes care of the temperature drift issue. One of the many interesting things that I am monitoring on this bird is the rotation rate. The bird started out with a rotation rate of .4 RPM, then something happened on or about December 28th and the rotation abruptly started to slow down to a minimum rate of .12 RPM (or 8.5 minutes per revolution) around the end of January, then it started to spool up again to a maximum rate of 1.16 RPM around the end of March, and then it started slowing down again.today at .65 RPM (1.54 minutes per revolution) with the curve trending down. I have taken many mind trips trying to rationalize what I am observing.but all those roads are leading somewhere near Albuquerque and I have no reason to go there (nice place though hihi). Let me know off line if you would like the graphics of my rotation study. Mark Spencer, WA8SME mspencer(a)arrl.org
