EQUiSat Optical Beacon CubeSat
by Trevor . 17 Oct '18

17 Oct '18

Students at the Ivy League Brown University are developing an amateur radio satellite EQUiSat that will carry a Xenon Flash Tube (XFT) subsystem to act as an Optical Beacon that should be visible to the unaided eye of observers on Earth.

LVB Tracker USB serial port driver for Windows 7 x64?
by Bill Bordy, NJ1H 22 Dec '16

22 Dec '16

Has anyone located a driver for the LVB Tracker internal USB to serial port adapter on Windows 7 x64? If not, has anyone reverted to the serial port connection on LVB Tracker and used an external USB to serial port adapter successfully with SatPC32 on Windows 7 x64? I have an Edgeport multiple USB to serial port that has drivers for Windows 7 x64 that I will use if I have to. I would prefer using the LVB Tracker with its USB to serial adapter if someone has another solution. 73, Bill NJ1H

AO-16 telemetry 3 Oct 2010
by Mark L. Hammond 01 Jul '16

01 Jul '16

Hi All, Here is a quick AO-16 update. On Sunday I turned AO-16 long enough to get some telemetry packets. The satellite would remain on for less than one minute after being commanded on. A quick test of the "bent pipe" voice mode repeater was successful. . The "hardware watchdog timer problem" is still evident; as expected, spacecraft temperatures are insufficient to keep the transmitter ON (needs to be above 15 deg C). Orbit projections suggest that satellite illumination conditions will not result in increased temperatures for nearly 10 years. Command stations do periodically turn AO-16 "ON" to check on its condition and see if the hardware timer problem has "automagically" fixed itself (which in not anticipated, but who knows...).

In addition: Good reception of sat carriers (+/- 2320.190 MHz) with AIDC3733 2400>144 converter (was modified for AO40 rx): receiver set at +/- 64.190 MHz (instead of 144.190) 73 de Michel F6HTJ ------------------------------------------------------------------------------------------------------ Hello all; for information here in south west Europe we use 2320,100 to 2320,300 cw/ssb portion of 13cm band for tropospheric , AS , RS, traffic. I have been told by Piero I5CTE there is permanent continuous carrier beacon around 2320.190 MHz (+/- doppler) by 1 of the 3 Sirius elliptic NA satellites. It appears reception is very good here with small 20 turn helix antenna (in spite of 12m heliax coax) peaking 539. Apogee (50000km ) around 325deg with 27deg elevation. F5BOF reports same signal with small hand held 25 elements f9ft yagi. So these are for us very interesting beacons. Depending hours we can receive 1 o 2 sats.

Re: Path to HEO
by Burns Fisher 01 May '13

One thing that would seem to be a concern to me is how to keep the attitude steady while the ion engine is firing. Yes, not much thrust, but to make the most of it, you want it pointing in as close to the ideal direction as possible. I don't know how the various probes like Hayabusa and Dawn do it.. Cold gas? Gyro? I would not think a bar magnet would be good enough (certainly not for deep space probes, but even for earth orbit). Starting to get more complicated. Another thought about the really cool energy analysis done by KK6MC: Besides the duty cycle imposed by wanting to be out of eclipse, there is another duty cycle imposed by the starting orbit and the desired eccentricity. For example if you were starting from a highly elliptical GTO and you want to get to high circular, you need to thrust mainly at the apogee in order to raise the perigee. If you are circular and you want to be elliptical with perigee equal to the starting height, you thrust at what will be the perigee to raise the apogee. (Of course you probably want to raise both ends some, and you may want to change the plane too but that's the general idea.) Thanks for bringing this up...great thought experiments, and that's how real projects begin! Burns, W2BFJ

Imagine RIT Festival May 4th - AMSAT Fox-2 Maximum Power Point Tracker Senior Design Project Exhibit
by Bryce Salmi 01 May '13

01 May '13

Hello everyone, I am a senior studying Electrical Engineering at the Rochester Institute of Technology (RIT) and I am a member of a senior design group that was sponsored by AMSAT to produce an engineering prototype *Maximum Power Point Tracker* (MPPT) for the Fox-2 satellite. Most members of our team are licensed radio amateurs and active members of the RIT Amateur Radio Club K2GXT and have had quite the experience with this project! We've worked extremely hard over the past 20 weeks to design and build a working MPPT. We'd enjoy sharing this experience with anyone interested. * Everyone who is in the Rochester, NY area or are willing to drive to the area is invited to come to the RIT campus this Saturday May 4th for the Imagine RIT Innovation & Creativity Festival <http://www.rit.edu/imagine/>. This is a completely free event on the RIT campus*.The previous link will have all the information to get here and find exhibits of interest. Also, here's a pretty concise video <https://www.youtube.com/watch?v=fsQoh-_xOmY> on what the event is about. The AMSAT Maximum Power Point Project is exhibit #491<https://www.rit.edu/imagine/planyourday13/exhibit.php?id=491>and will be located in what is known as the "infinity quad" outside the engineering building (There's a big Mobius strip in the middle). We're pretty much in the center of outside activity which is very nice for showing people our project. - Google StreetView of the Infinity quad/loop<https://maps.google.com/maps?q=Rochester+Institute+of+Technology,+One+Lomb+…> - 2013 Imagine RIT Festival Map<http://www.rit.edu/imagine/planyourday13/images/2013_map.jpg>(We will be between the orange GLE and red LBR, you'll see a star, mobius strip, and question mark on the map where I am referring too, sorry if it's not clear) Our project is part of the Kate Gleason College of Engineering senior design program and we proposed this project as a group last Summer. Tony Monteiro has been our "customer" for the project and has been great to work with. You can find out more information on our P13271 RIT EDGE wiki<http://edge.rit.edu/edge/P13271/public/Home>which is pretty up-to-date pending a few updates (since PCB bring-up) but largely a great resource for those interested for a more in-depth look into our project. We have not completed our project but will be displaying the working prototype MPPT during the festival and be more than happy to explain/show it to anyone interested. There are some final tests and reports that are left to finish before our project is complete. Some links to high-interest items on our EDGE Server: - 1 Page Project Summary<http://edge.rit.edu/edge/P13271/public/FinalDocuments/Planning_Execution/1_…> - Project Poster<http://edge.rit.edu/edge/P13271/public/MSD_Poster/MSD_Poster_r1.pdf> - MPPT Block Diagram<http://edge.rit.edu/edge/P13271/public/FinalDocuments/Systems_Design/High-L…> - MPPT Schematics<http://edge.rit.edu/edge/P13271/public/KiCad/MPPT/trunk/AMSAT_7W_MPPT_Schem…>(slightly out of date, some final values will be updated soon, largely up-to-date) - MSP430 firmware information<http://edge.rit.edu/edge/P13271/public/Health%20%26%20Status%20Firmware> Well, I think I've thoroughly linked to areas people might have interest in. Feel free to poke around the project documentation and learn more or ask questions. If you have any questions about Imagine RIT or anything related to the festival please ask as well. I look forward to potentially seeing some of you at the festival! Sincerely, Bryce Salmi KB1LQC Project Manager P13271

SatPC32 more info on problems and THANKS!
by James Luhn 30 Apr '13

30 Apr '13

I sincerely appreciate all of the feedback on my SatPC32 issues. I figured out the Ghost tracking' issue or at least corrected the problem. Somehow my location became corrupted. I noticed that the little white dot (QTH) was missing from its normal location. By some means my latitude/longitude data changed. I have put in the correct numbers now and I expect the ghost will leave the area. As was mentioned, the issue in which all control stops is probably an interface problem. It may even be the notebooks having older firmware. I will continue to tinker in that area. The Panasonic Toughbook is a nice computer for ham work as it has both USB ports and a true serial port. The fact that the LVB Tracker works flawlessly with my Macbook through the same USB cable, more than likely this problem is Panasonic Toughbook related. I did try both USB ports on the Toughbook and had the same results. I will keep everyone informed as to how I resolve my problem. Thank you again for all of the responses. I feel sure I am on the correct path to making all of the components play nicely together. Of course progress is slow when there is a satellite above the horizon :) 73, -james W5AOO

Re: Path to HEO
by Joe Leikhim 29 Apr '13

29 Apr '13

Even if the technique required 5 years to advance to HEO it would be a positive step since the amateur launch opportunities directly to HEO are measured in decades and the cost in 10's millions of dollars. This reminds me of a commercial payload that failed to make GEO. The folks at AGI (STK Satellite Toolkit) devised a path circling the moon which used the lunar gravity to accelerate and return the satellite to its intended GEO position without depleting much of its limited station keeping fuel. -- Joe Leikhim Leikhim and Associates Communications Consultants Oviedo, Florida JLeikhim(a)Leikhim.com 407-982-0446 WWW.LEIKHIM.COM

Dayton, Satellites, Fun !!!!!
by James Luhn 29 Apr '13

29 Apr '13

I am gathering up my clothes for my trip to Dayton. I hope to see and meet as many satellite folks as possible! I have my name in the hat to work at the AMSAT booth. I worked last year and had the best time! I keep seeing many emails about what satellites are operating. It seems many think that none are working. Well I can tell you that I am having a blast working FO-29, SO-50 , VO-52, and grandpa AO-7. I do admit that AO-7 has a bit of a stutter step when too many get on or someone cranks their power up too much. Take a look at the link Bob, W7LRD, posted regarding active satellites: http://aar29.free.fr/sat/indexlogin.php Each contact is so exciting. OMG, I worked Brazil last night too! FO-29 sounded just like 20 meters last night! It is so nice to hear those making their first contact and so nice to renew old friendships. Hope to meet you or at least work you! 73, -james W5AOO ...still excited about amateur radio after being active for 50+ years!

Sat32PC
by James Luhn 29 Apr '13

29 Apr '13

I need some advice. I have been trying to run Sat32PC to track satellites with my G5500 rotor and LVB Tracker. It seems I am running into one problem after another. Many times the program stops working when I get towards a lower elevation while tracking the satellite. I get most of the pass and then everything stops. I cannot park the rotor and must reboot the computer as restarting the program gives com errors. This afternoon Sat32PC was tracking a ghost. It clearly thought something was flying above. The only satellite I had selected was FO-29 and it definitely was well past a fly over. In fact, I could not find an amateur satellite that was anywhere that the program should be tracking. I would really like to get the bugs out as I plan to use my Panasonic Toughbook in a portable operation. I am using the XP Professional operating system with the USB communicating with the LVB Tracker. I also have a Macbook and MacDoppler has operated flawlessly. It does what it is suppose to do and does it well. Please no flame wars over Mac vs PC. I use both and basically am happy with both. On Sat32PC, the Keps are updated so I am not feeding the controller wrong info. On the screen, the satellite position is visibly correct. On the bottom of the screen the Azimuth / Elevation were wrong when it was tracking the ghost. I have two Toughbooks and both exhibit the same problem. Has anyone had the same or similar problems? 73, -james W5AOO

It's the same thing, what gets you from 310 to 700 km can also get you to 7200 or 20000 km. But first the technology needs to be proved in Space CubeSats like Romit-1 will do that if they can get launches. Bob, on the topic of extending orbit lifetime there's a UK company, a University of Southampton spin-off, who are doing some interesting work in this area. Mars-Space Ltd have developed a Pulse Plasma Thruster for a 1U CubeSat designed to extend orbit lifetime which was shown at a recent CubeSat Workshop, details at http://www.mars-space.co.uk/Pages/MicroPPTforCubesats.aspx They are also working on Ion Motors. 73 Trevor M5AKA

Romit-1 and the other CubeSats testing ion engines will definitely give us something - proof that it works in practice or an opportunity to learn from any problems / design issues that arise. Given that Space is a demanding environment I'm sure not all the ion motor CubeSats currently being developed will work as planned when deployed, it'll be a learning experience. Going from a 310 to a 700 km orbit in a year using the limited solar power generated from a standard 2U CubeSat will be a major step forward. It follows that to get up to 7200 km or even better 20000 km will take years but could be speeded up by having CubeSats with large fold-out solar panels and more powerful motor. I say CubeSats rather than Microsats because of cost, a 35 kg microsat could cost $1 million just to get into LEO. I hope the various groups that have developed ion motor CubeSats are eventually successful is getting launches to LEO to test them out. 73 Trevor M5AKA ----

>In addition, doesn't the process getting from GTO to HEO require some form >of rapid acceleration? If yes, ion engines and solar sails are out. The main requirement for escaping from LEO is that the engine thrust must exceed the atmospheric drag force. The time required to reach a HEO orbit mainly depends on how much electrical power you can generate, more power means more thrust and a faster ride to the desired orbit. A Cubesat power budget will be somewhat limited, deployable solar panels might help somewhat. Most Cubesat launches are deliberately sent to low orbits to insure rapid reentry and burn-up to meet orbital debris requirements, that is why Cubesat launches to GTO are rare. A higher orbit will require a disposal plan, but electric propulsion can help with that too. Please see my paper in the 2012 AMSAT Symposium Proceedings. Dan Schultz N8FGV

910 MHZ AMTV Reception
by Les Rayburn 27 Apr '13

27 Apr '13

Just realized that my Icom R-7000 with the NTSC TV Adapter should be able to receive these signals. I've got a nice loop Yagi for 900 MHz as well sitting in the attic. Just sold the receiver on Ebay, but not shipping it until Monday morning--so may have to try to receive a pass over the weekend. Sounds like fun! I sold the R-7000 thinking that I'd simply replace it with a FunCube Dongle Pro at some point. Never dreamed that I'd have a nearly immediate use for my old standby. Ah, well. -- 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf 6M VUCC #1712 AMSAT #38965 Grid Bandits #222 Southeastern VHF Society Central States VHF Society Life Member Six Club #2484 Active on 6 Meters thru 1296, 10GHz & Light

For the digitally challenged-what is the easiest way to input new keps? Use monosyllabic words..keep it simple for simple people. Been messing around for a couple of hours & ready to heave the computer out the window. 73 Bob W7LRD

SATPC32 and New Sat KEPS
by Les Rayburn 26 Apr '13

26 Apr '13

Like many, I'm eager to track the new satellites launched over the past few days. If everyone will pardon more newbie questions, here goes: 1.) How do I input the published KEPS data for the new satellites into SATPC32? 2.) How long before the standard files (amateur.txt, etc) will be updated to include the new birds? -- 73, Les Rayburn, N1LF 121 Mayfair Park Maylene, AL 35114 EM63nf 6M VUCC #1712 AMSAT #38965 Grid Bandits #222 Southeastern VHF Society Central States VHF Society Life Member Six Club #2484 Active on 6 Meters thru 1296, 10GHz & Light
