[amsat-bb] Re: HEO Arsene AO-24
I was thinking of the mode S linear transponder portion of the satellite. It had a narrow passband and produced about 1 watt. You needed a 4-6 foot dish for the downlink. Since a 3U cubesat can generate about 6 W of DC power with solar panels and the largest surface for mounting antennas is 11.5 x 3.5, this would be the kind of satellite that we could expect for an $800k launch cost. 73, John KD6OZH - Original Message - From: f6...@aol.com To: amsat-bb@amsat.org Sent: Friday, February 04, 2011 15:44 UTC Subject: [amsat-bb] HEO Arsene AO-24 Here is a detailed description from the past (sorry found only in French) http://www.amsat-france.org/spipamsat/IMG/pdf/Descriptif_ARSENE.pdf and photos: http://www.amsat-france.org/spipamsat/article.php3?id_article=61 73 de Michel F6HTJ ___ Sent via AMSAT-BB@amsat.org.

Suitsat 2/ARISSsat is a linear transponder done with DSP.

You could also make a better transponder by forming filters around the uplink signals so downlink power isn't wasted by repeating noise and downlink power could be allocated equally among users.

See: http://pmddtc.state.gov/ The criteria is obviously determined by the State Department with direction from the Congress. The article just tries to describe some examples without trying to justify or explain why something is or isn't a munition. The main point of the article is that any communications satellite, whether it is an Amateur, a university or a commercial satellite is considered by ITAR to be a munition controlled by ITAR export regulations. That's a fact and to understand the criteria is to understand the thinking of the authors of the regulation (State Department and the Congress), which I can't do. To be sure, export regulations can be complicated and at times appear to us as being irrational. But the fact remains, ITAR is an export law that we at AMSAT have to comply with.

FDMDV uses a 1400 bps codec, occupies only 1100 Hz and operates with any SSB transceiver. Comunications doesn't have to be full duplex. At 12-16 kbps the satellite and ground stations could alternate with short bursts of voice or text. This wouldn't fit in a 2.4 kHz SSB bandwidth but would require a 16-20 kHz wide filter or use of a transverter and a simple SDR radio like the SoftRock. 73, John KD6OZH - Original Message - From: Gordon JC Pearce gordon...@gjcp.net KD6OZH's mentioning of a 1200 bps voice codec is very interesting, too. I see that DSTAR's AMBE is down to 2000 with error correction, and Speex operates down to 2000, too, though I think without error correction. (I find the latter much more engaging as a ham, since it is open source.) It would be a hoot to do a voice conference over the Internet using a sample of low bitrate codecs and just get a sense of what might be possible. One downside of voice is that it would occupy the transponder far more than messaging, and Bob's favorable power calculations would need to be estimated downwards. Would the packet satellite be capable of bent-pipe operation though? You'd need to transmit and receive simultaneously to get that working.

AMSAT shouldn't just sit around waiting for the right political climate for P3E. 73, I think that despite the difficulties in communication and personality clashes, there is a great deal of agreement on the list about what we want as a group. We all want a HEO amateur communication satellite in orbit, some of us because we've never had that experience, others because it is our fondest memory of AMSAT operations. Barring that, or perhaps in addition to that, we want to ensure that there are long-range linear-transponder birds available in the future. Oddly enough, despite all the rancor in recent days, none of it seems to be around this core purpose of our group. Some of our members seem to be concerned that because AMSAT is not pursing this in a wholly direct way or because it is undertaking projects of increased technical difficulty, it is therefore delaying the fulfillment of the above primary goal. It is my impression that the board members do not share this view. They feel that the current impediment to a HEO launch in full-price launch costs is so great that, for instance, the thousands spent on SuitSat2 would never make a difference, since it is less than a thousandth of the full price. Instead, we should make the best of opportunities in LEO that might support our future work in HEO, MEO, or wherever. SuitSat2, since it will be the inaugural flight of the long-planned SDX, is seen as fitting the strategy well. SDX is part of P3E and proof that we are technically adept. This proof will be handy for AMSAT-DL as it pursues the clearest path to the launch of P3E, namely through government money that anticipates the mission to Mars. According to this argument, pulling for P3E is no longer a matter of saving pennies, but rather a matter of strutting our stuff, and SS2 is a great way to strut and strut quickly. In this climate, enthusiasm for SDX, SSE and, ultimately, P5 might be worth 100x any amount in cash that we could give individually or as an organization. Finally, SS2 provides a way of testing a core technology that might become part of a module of a future bird, one built rapidly around a launch opportunity. I have to say that this strategy for fulfilling our common wishes makes good sense to me. It is predicated on some facts which I accept at second hand: the high cost of HEO; the lack of government sponsored launches in NA. I'm sure that the board would be delighted to have their dismal assessment of *that* situation refuted conclusively. If it cannot, then we must accept that sometimes the fastest route is not the straightest path, but if we feel that this board is not guiding us well towards our goals, we have the opportunity to replace our pathfinders. 73, Bruce VE9QRP John KD6OZH - Original Message - From: i8cvs domenico.i8...@tin.it To: John B.

[amsat-bb] Re: Increasing range from LEO.
To get good coverage you need as many LEO satellites as possible so they should each be as small as possible. Intersatellite linking could be done via automated ground stations. This eliminates the need for high-power transmtters and/or high-gain antennas on the satellites for interlinkng. It's better to put that gain and power consumption on earth. Eveything on the satellite costs more than its weight in gold as launch costs are $700 per ounce. 73, John KD6OZH - Original Message - From: g0...@aol.com To: kd6...@comcast.net ; amsat-bb@AMSAT.Org Sent: Thursday, September 03, 2009 18:16 UTC Subject: Increasing range from LEO.

Clearly the kind of mistake that caused the catastrophic failure could have happened on any spacecraft assembled by any organization. nope. OK anyone has a statistical chance of dying or any project has a statistical chance of failing but the more complex a project is the more likely it is to fail...and AO-40 as it grew more complex needed larger size which then needed a more powerful rocket engine...which ... this is mission creep (or more correctly design creep) and as I noted it is a common cause of failure among homebuilders. Unless you are rolling your own (ie doing the aerodynamics yourself) most home builders build something that professionals have at least deigned. Where they get into trouble is when they start adding things and making the project outside the scope of what was well understood. had AO-40 not been supersat it would not have needed the larger engine... You can call it simple if you like but a) it remains firmly affixed to earth and b) it is being sold to the German government as an adjunct to a mission to Mars.

For the last time (from me, I promise) we have been told in no uncertain terms that the cost for a launch to GTO that would carry a craft of the size required to provide a happy medium of solar panels and antennas will cost no less than $6 million US and maybe as much as $8 million. If that is the case then we are, after 3E gets its launch done in HEO sats...a reasonable hope is that with some new launch vehicles coming on IE Falcon9 etc there might be some opportunities for reduced rate launches...but who knows. What I wonder is if there is any reluctance on the part of launch vehicle providers after the 40 incident to let amateur propulsion ride on their vehicle. It is after all rocket science.

Is this our future ride to the moon? MM The Amateur radio community does not have the resources to build a better communication system than a professional commercial company. So we have two options, use existing lander hardware for communication or design our own stand alone transceiver project that just uses existing power and or antennas. After the lander has released the Rover, the lander “May” have some unused resources. Lets see if any of these unused resources (if any) can be used for Amateur Radio projects. How is the Lander going to be powered? Batteries only: If so, there will be no power for projects. The lander telemetry will stop after a few days. This is not a likely scenario. Solar Panels and Batteries: In this option, there may be some available power during lunar days to run other projects. This is the most sensible solution. Atomic Battery: This is the best option, however it’s politically sensitive. http://en.wikipedia.org/wiki/Atomic_battery The power source is one of the keys to designing a possible Amateur Radio project. Let’s ping our contacts at NASA and see what we can learn about the Moon Lander projects. Flash Back: On ISS, the Russian team proposed that we re-use navigation antennas from the FGB modules for Amateur Radio (1996). The idea worked and on the very first ISS mission we had access to an already installed antenna. It was a simple idea and it worked. Education Spin: Contributing to the project from a scientific nature may be difficult, we will have to get some universities involved, or we could focus on the educational nature of the project.

The problem is that amateur radio doesn't significantly reduce the cost of a satellite. Any interest by the Red Cross would not be in the satellite but in human volunteers that might come with it.

[amsat-bb] Future satellites
An interesting question for the short term is what can we do with 1 watt of RF from a LEO satellite. RS-10 and RS-12 were interesting as they required only omnidirectional antennas but they had a lot of power available as they were attached to much larger satellites. AO-16 was a small satellite but was capable of only 1200 bps data using uncoded BPSK and simple vertical antennas. Given the type of hardware developed for Suitsat-2, we should be able to do a lot more. Using modern error-correcting codes 4800 bps is possible using omnidirectional antenas and with modern codecs that can carry 4 voice channels or 3 voice channels plus 40 PSK31-like channels. With 10 dBi of gain at the ground station the data rate and number of voice channels could be quadrupled. The downlink could also be split between 2 voice channels for use with omnidirectional antennas and 8 voice channels for high-gain antennas. 73, John KD6OZH I have extracted from it the most important following part: 73 de i8CVS Domenico Extracted from G3RUH article THE EARTH MOVES An example, 1 watt transmitted from a 20 dbi gain dish on the Moon, received on a 1.2m dish at Earth with a system noise temperature of 100K results in a signal to noise ratio in 2.4 kHz bandwidth of 10.5 db. (Note that frequency matters not). This would support one rather noisy SSB voice signal. Alternatively it would carry an error-free 2400 bps binary PSK data transmission without coding, 9600 bps with modest coding [2]. ___ Sent via amsat...@amsat.org.

Actually, its very bad as it barely supports 1 user at 3 times the proposed maximum power level. You could support 100 users on a HEO with the same SNR and power output. Most users will consider 10 dB SNR to be marginal and want another 10 dB of signal strength on the downlink. The same amount of power has been consumed by 10 stations on HEOs. 73, John KD6OZH - Original Message - From: Joe To: John B.

[amsat-bb] Re: The Moon is our Future
A more meaningful appoach for an exercise like this is to start with DC power input for the entire package. Receivers consume power and transmitters (especially linear ones) are inefficient and the efficency goes down with increasing frequency. On the moon, you also have to heat the electronics at night to prevent failure. Linear microwave power amplifiers have 20-35% efficiencies and VHF amplifiers might reach 50%. You can make more efficient amplifiers by converting the output signal into magnitude and phase or frequency components and using class C, D or E amplifiers. However, the added circuitry (whether analog or digital) also consumes power. FM makes sense for single channel transponers as the amplifiers can be nonlinear and you can get 80% efficiency at VHF. SSB amplifiers have a double inefficiency as you must design for peak power output which is 4-5 times the average power output. Amateur HEO satellites have used SSB for multichannel applications as you can count on the voice peaks for different users to occur at different times and design for the average power of all users. However, you need lots of users to reach this goal. 73, John KD6OZH - Original Message - From: i8cvs domenico.i8...@tin.it To: Joe n...@mwt.net Cc: Jack K. kd1p...@gmail.com; AMSAT-BB amsat-bb@amsat.org; kg4...@gmail.com Sent: Friday, July 03, 2009 14:41 UTC Subject: [amsat-bb] Re: The Moon is our Future Hi Joe, The specification given by Miles WF1F is for a Lander transmit power of 5 to 10 watt in 70 cm from the moon.My calculation shoves that a single SSB station to be received in 70 cm with a S/N ratio of 10 dB on the earth a power of 10 watt in 70 cm is necessary on the moon.

[amsat-bb] Re: The Moon is our Future
HEOs are illuminated 99% of the time and LEOs are illuminated 50% or more of the time with eclipses by the earth lasting only 45 minutes. Thermal inertia can keep the temperature from swinging too far in either direction. Since the satellite is in a vacuum, heat can only be radiated away as in a Dewar flask. On the moon, the eclipse lasts for 2 weeks so more cooling occurs. During the other 2 weeks, heat from the electronics and solar illumination must be radiated away. Every lander that I have seen has a few spindly legs so there won't be much heat conduction to the moon's surface. However, I'm not an expert on thermal design. When I was designing a 70 cm receiver for AMSAT, others did the thermal analysis. Nothing behaves in space as it does on Earth as there is no convection cooling. Building a prototype that works on Earth for project like this is only a few percent of the effort required. Treating it as a radio club project won't be effective as people need to sign up for a 5-year project. If your making an add-on to a NASA project you have to fit into their shedule, design to their specifications, produce the documentation that they need, travel to their test facilities and pass their tests. There are also legal requirements (ITAR) when working on space-related projects. 73, John KD6OZH - Original Message - From: Joe To: John B.
