[amsat-bb] Re: Cubesat 1 axis attitude control?
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. 73 Colin VK5HI. -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org] On Behalf Of Robert Bruninga Sent: Friday, 21 February 2014 07:58 To: amsat-bb@amsat.org Subject: [amsat-bb] Cubesat 1 axis attitude control? 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.

Stefan, I wholeheartedly support your comments. We made a conscious decision many years ago, that in retirement, we would support the Cubesat Program by downloading their telemetry, to give something back to the hobby. Being licensed nigh on 50 years ago and being part of the Amateur Satellite Service for most of those, I would like to think that these young Cubesat designers may become the Amateur Satellite builders of the future, but I doubt I that may be around to reap their rewards. Then again I have been mistaken before. Personally I do not care if a satellite has an OSCAR moniker, we just download whatever telemetry is available from the current Cubesat satellites to assist them in their ongoing analyses. This is not the first time this has been raised, as I remember a few years back, Bob Bruninga raising the topic in respect to one of the satellites he was involved in.

Thanks, Cubesats working within the amateur radio frequency spectrum are commanded by licensed ham radio operators with the same rights and requirements as all of us. Many of them use the frequencies to downlink vital satellite information as well as scientific experiment data. All of this is well within the amateur radio service rules and a very positive contribution by our community to science and education. Your question are valid and they need to be addressed in a constructive, supportive environment where the community works together. I would encourage you attend one or more of the many annual cubists conferences and engage these folks. You certainly have enough to offer! Now having said that, cubesats are a wonderful addition, not a threat and show the diversity of our community. I am always amazed by the ignorance displayed and self-proclaimed expert label used by some as an argument to deny parts of our community their right to use small satellites with amateur radio on board. Interestingly, none of the amateur radio operators working with cubesats have ever argued against HEOs or denied the rest of us that right by questioning how and why we use the spectrum!

Then, they should determine if it is possible to comply with the requirements of the amateur-satellite service or if licensing and operation should be in some other radio service which is more consistent with the nature and requirements of the mission. A. The purposes of an amateur satellite should be: (1) To provide communication resources for the general amateur radio community and/or (2) To conduct technical investigations in all respects consistent with the Radio Regulations. [See RR S1.56 and RR S1.57.] I have great doubts with many off those CubeSats, if they comply to number (1) The only communication resources they provide is for themselves by a cheap downlink system, by using hams to receive data for them. This is not for the general amateur radio community as mentioned in number (1)... The option they have is to go to some other radio service which is more consistent with the nature and requirements of the mission. 73 de PE1RAH, William Would recommend reading the info on AMSAT's website! http://www.amsat.org/amsat/amsat-na/oscar.html Stefan, VE4NSA ___ Sent via AMSAT-BB@amsat.org.

[amsat-bb] Re: New Control Software
Angelo, Further to Drew's comments I would confirm the 1268.703 uplink. One further hint besides deviation and frequency, is to set the TXDelay to 1000 milliseconds. This will ensure all the switches or relays in the system have settled prior to issuing the uplink packet. If you find this to be the issue, reduce the TXDelay in 50 or 100 milli-second increments till you have reliable acks. When AO-51 was flipped and favoured the Southern Hemisphere I was able to get acks from horizon to horizon and rarely did it double request. I use 25 watts output via about 12 metres of 5/8 inch hard-line to a 15 turn helical. With your system you should do just fine. The other issue that Drew commented on was deviation. In the absence of test gear, a method I have used, is to listen to the audio level on the downlink, then preferably compare your TX signal level in the same Transceiver, but a separate RX will suffice. It will be very apparent if you are under or over deviating. Not very scientific, but when you have limited test gear, its a way forward. 73 Colin VK5HI. -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org]on Behalf Of Angelo Glorioso Sent: Friday, 19 February 2010 14:07 To: Andrew Glasbrenner Cc: AMSATBBS Subject: [amsat-bb] Re: New Control Software I appreciate the helpful hints.

Can a schedule mode be requested for the BBS for V/U??? Oh well, as you said, it is a low priority. V/U BBS was discontinued because it interfered with control of the satellite, so no, we won't be scheduling it without the upgrade even if requested. We have many L/U users on several continents, but it does require a very good station. The equipment you describe should be adequate...it's similar to what I use. The deviation and frequency is very important to be successful. My uplink is about 3 khz high than listed. Since you have an excellent L/U analog uplink, I'm confident the devil is in the details with your digital setup.

[amsat-bb] Re: AO-51 reception report
Reid, I refer you to ANS-340 posted recently to the -bb. The FLIP experiment has been a success. Additionally, A number of positives and negatives have resulted from the experiment. Positives. AO-51 has increased its spin rate. Reception in the Southern Hemisphere is much improved. Negatives The antennae are not favouring the Northern Hemisphere, hence signals are down. The flip has introduced a significant precession component that is affecting reception in the Northern Hemisphere, through fading and polarisation changes. The Command Team are waiting for AO-51 to stabilise, prior to executing another FLIP, to return AO-51 to its normal attitude. 73 Colin VK5HI.

[amsat-bb] Re: AO-51 S band off
Luc, I am not too sure what you are attempting to imply in your post. First up there are 8 members of the operations group. Their task is to analyse the numerous requests that are submitted to ao-51modes at amsat.org and prepare a schedule in conjunction with the command stations. On occasions it becomes nigh on impossible to facilitate all the requests, so some are held over to the following month. As you are aware that schedule is posted to the Amsat-NA site at http://www.amsat.org/amsat-new/echo/CTNews.php OR If there is a delay in posting to the Amsat-NA site, a post is made to the amsat-bb, which Drew did on this occasion. In respect to command stations there are currently two, plus and one in training. Operating a command station is a dedicated and responsible task. It also requires a commitment to be able to drop tasks at hand and attend to daily commanding tasks and analysis, not to mention the training to become a command station. Your assertion that if Drew is not available, then the World stops is totally incorrect. In Drew's post that you have misunderstood, is that he was responsible for executing the new mode changes. He stated that he encountered an equipment problem and the remainder of the tasks would be executed over subsequent passes. This was a totally responsible action on his behalf. The tasks that were not fulfilled did not place AO-51 in jeopardy. What you overlooked is that the Operations Group and the Command Stations are all dedicated volunteers, and most work for a living. However we do work as a team, day in, day out.

Drew, Thanks for that. Better to be safe than sorry. 73 Colin VK5HI. -Original Message- From: ao51-modes-boun...@amsat.org [mailto:ao51-modes-boun...@amsat.org]on Behalf Of Andrew Glasbrenner Sent: Monday, 2 November 2009 11:15 To: Amsat-BB; AO51 Modes Subject: [ao51-modes] AO-51 S band off The S band transmitter is now off, and 435.150 telemetry is back on. The L uplink is not yet back on for the PBBS. I had some temporary equipment problems here and instead of risking getting halfway through some steps and failing, I am stretching the mode change out over a few passes. 435.300 is back up to over 500 mw. The L uplink for the PBBS should be back on tomorrow, and the new schedule should be posted by tomorrow night. Sorry for the delay. 73, Drew KO4MA ___ Via the AO51-modes mailing list courtesy of AMSAT-NA ao51-mo...@amsat.org http://amsat.org/mailman/listinfo/ao51-modes ___ Sent via amsat...@amsat.org.

[amsat-bb] Re: CP6 Decoding
Jim, Mike DK3WN and I have done some work evaluating CP6 Decoding. Like you we have difficulty decoding CP6 with hardware TNC's. Best performance is to use MixW, with audio from the data port. We have passed this information to the CP6 Team who are investigating the TNC Header that CP6 sends. It is also important that you tune the lower tone to 1200 Hertz. In my case I use Spectran to monitor the audio. I will forward you a small .wav file separately that has two good decodeable bursts that you can use to evaluate your system. Best regards, Colin VK5HI. -Original Message- From: amsat-bb-boun...@amsat.org [mailto:amsat-bb-boun...@amsat.org]on Behalf Of James Denneny Sent: Wednesday, 17 June 2009 00:53 To: amsat-bb@amsat.org Subject: [amsat-bb] CP6 Decoding I am troubleshooting a CP-6 decoding problem. I have excellent copy on CP-6. Keps are good. Signal is strong but no decode. Equipment is IC-910H and AEA DSP2232. I checked everything out with APRS FM copy on 144.390 using hyperterminal - good copy in FM packet. PC TNC use com 3 - 9600,8.N,1 to communicate. PC flowcontrol is hardware. DSP2232 is set for MOD p12 (p1 1200bps). I do not see any TNC lockup during data bursts. Radio is set for LSB when tracking CP-6. I even tried using hyperterminal connection in lieu of CP-6 decoder.
