I'm surprised no-one else has done the math on this. The website says they'll launch 30 tubesats on a flight. 30 x eight grand comes out just under a quarter million US dollars - and they say this will cover *all* associated services as well as the launch. I find it rather hard to believe that even the launch vehicle would only cost US$240K per flight. -- 73 Richard W L Limebear G3RWL g3rwl(a)amsat.org FOC # 1188 So many beautiful girls ...

New videos demonstration of my tinny transponder
by William Leijenaar 06 Aug '09

06 Aug '09

Hi AMSATs, Everything has been prepared for the Ham Fair in Tokyo, so I got some time to make some new video demonstrations of my tinny transponder. On the AMSAT-BB I see some interresting articles about launch options, will see what the future brings. I am looking for something smaller than 1U cubesat, I worder if that can be done. In the following video I show my transponder design in a CubeSat model that I made from transparent plastic glas. http://www.youtube.com/user/pe1rah#play/all/uploads-all/1/WTeHP6j75X4 The transponder only takes a small amount of volume, and might fit in most CubeSat experiment satellites. Another option is to put one in a half CubeSat-structure. I don't know if there are also quarter Cube structures ?? Maybe it can reduce costs. Or have 4 in space for the price of 1U Cube... Because the transponder and its connections are very small I made a Demoboard for easy testing and using. In my second video I give a demostration of this Demoboard, on which the transponder can be placed and connected. http://www.youtube.com/user/pe1rah#play/all/uploads-all/0/hy56TPVGTuQ The Demoboard has an onboard 3.7V regulator which allows input voltages from 5V up to 15Vdc, which can be done in the way of a small supply adapter. The RF connections are all SMA, for easy testing and easy using. In case of terresterial use where weight is no problem (E.g on top of mountain) the Demoboard can be used as well. On the SMA 2m output a linear power amplifier can be connected to boost up the RF power. The 200mW output of the transponder is enough to drive E.g the 2m all mode Mitsubishi M57713 power module, giving you almost 20W RF power. The Demoboard I will demonstrate at the Ham Fair in Tokyo. There the ham people can see it is not an hot air castle but real working hardware. Enjoy ham radio, Hope to meet you at the Ham Fair in Tokyo, 73 de PE1RAH, William Leijenaar --- _________________________________________________________________ Express yourself instantly with MSN Messenger!

DM54/DM55 on Saturday (8 August)
by Patrick STODDARD (WD9EWK/VA7EWK) 06 Aug '09

06 Aug '09

Hi! I will drive to eastern Arizona for the afternoon/early evening of Saturday, 8 August 2009, and plan to work FM satellite passes from the DM54/DM55 grid boundary in Apache County. I should be able to work AO-27 passes at 2046 and 2227 UTC, an AO-51 pass at 0041 UTC, and an SO-50 pass at 0134 UTC. Local surroundings will determine if I can work an earlier AO-51 pass at 2306 UTC. If I feel like staying out there into the evening, and if the western view from there is not obstructed with lots of hills and mountains, I *might* work the later AO-51 and SO-50 passes from there. No guarantees for those passes (AO-51 @ 0223 UTC, SO-50 @ 0315 UTC). As with other recent road trips, there is no need to first send me a QSL card to get one for a DM54/DM55 QSO. Please e-mail me directly with QSO details, and - if you're in the log - I will send a card your way. For those who worked me last month on my 3-state 14-grid road trip, I will hold off mailing those cards out until next week. This will let me put a DM54/DM55 QSL card in the same envelope, if I work you out there on Saturday. 73! Patrick WD9EWK/VA7EWK http://www.wd9ewk.net/

Mast mounted Pre Amps? what to use?
by racer5039 06 Aug '09

06 Aug '09

I would like to ask the group what there thoughts are on Pre Amps? I'd like to go with an amp that is mast mounted and can handle some power through it.(auto Switching) I have the antenna system down right for some mods and with the sale of some other toys I have saved up for a good one. What are you using or would your recommend? Thanks Marv N0FJP

BEVO1 Deployment from STS-127
by Karla Vega 06 Aug '09

06 Aug '09

The University of Texas at Austin deployed BEVO1 in space on July 30, 2009 at 7:27 AM CDT via the STS-127 Space Shuttle Picosatellite Launcher (SSPL). We appreciate anyone who can help us tracking BEVO1! BEVO1 Downlink Information: Beacon Mode Downlink Freq: 437.325 MHz Modulation: FM, 200mW, Morse Code, ~20 WPM Data Mode Downlink Freq: 437.325 MHz Modulation: GMSK, 1W, 9600 baud, AX.25 (default) FM, 1W, Bell 202, AX.25 TLE's: 1 99999U 9211.52399245 .00015326 99081-9 77971-4 0 19 2 99999 51.6397 84.3142 0004954 91.3966 248.8994 15.80682654 2322 BEVO1 is a 12.5 cm cube and 3 kg in mass. The purpose of the mission is to collect data from NASA's DRAGON GPS receiver. BEVO1 has two modes, data and beacon. The data mode is on over most parts of the United States, and the rest of the time, the satellite is in beacon mode. Also, anyone tracking BEVO1 can record what they hear at http://paradigm.ae.utexas.edu/opsThe University of Texas also has additional information at: http://www.utexas.edu/news/2009/06/09/picosatellite/ NASA describes DRAGONSat as an anticipated eight-year program with a launch of the satellites approximately every two years. The first three missions will test individual components and subsystems while the final mission will culminate with the successful docking of two satellites. Refer to http://tinyurl.com/m2blyc for additional mission information. The University of Texas at Austin has developed BEVO1 and Texas A&M University has developed AggieSat-2 for this mission. Both satellites will perform the initial data acquition testing of the DRAGONSat program.

Fwd: Launch your own satellite for only eight grand
by Mark Thompson 06 Aug '09

-----Original Message----- From: djmullen tds.net <djmullen(a)tds.net> To: BARS <bars(a)cs.wisc.edu>; Joe <joe(a)dzsp.org> Sent: Tue, Aug 4, 2009 11:46 pm Subject: [BARS] $8000 to launch a satellite? Here's an interesting article from The Register: http://www.theregister.co.uk/2009/08/04/tube_sat/ Launch your own satellite for only eight grand Prospective world domination candidates apply here By Bill Ray • Get more from this author Posted in Telecoms, 4th August 2009 14:59 GMT Interorbital Systems is offering your own orbiting satellite for only $8,000, including launch, though evil geniuses might balk at the expected 2-week lifespan before a fiery re-entry. The plan is to launch 32 of the diminutive TubeSats into low earth orbit, around 310Km up, using a single Neptune 30 launcher (under development by=2 0Interorbital). The Neptune 30 will time release the TubeSats into orbits that decay within a few weeks, after which they'll burn up re-entering the Earth's atmosphere. The cost of each one is $8,000, though you'll have to pay up front to guarantee a launch slot, and put the satellite together yourself from the supplied kit. Stil, at least Interorbital Systems accepts PayPal. Fitting a doomsday machine into the 13.5cm long TubeSat, which is only 8.7cm wide, will challenge plans for world domination, but that will be where the "genius" comes into play. The company suggests you might use your TubeSat for everything from "Earth-from-space video imaging" to "private e-mail" or "On-orbit advertising", though we're not sure what the audience figures would be for the latter. More realistically, buyers might like to bounce amateur radio signals off their own bird, or try experiments within orbital conditions. The radio aboard the TubeSat will operate at 902-928MHz or 2.4-2.4835GHz, the latter being ideal for Wi-Fi, as well as covering the bands allocated for amateur satellite operations - allowing Hams to fly even if pigs can't. Full specifications are available from Interorbital (pdf). Not that professionals will be allowed to buy TubeSats: "The listed price is not valid for military, governmental, or large corporate entities. Members of these organizations should contact Interorbital Systems if interested in purchasing a TubeSat". Interorbital Systems has some form in space operations. It was a competitor in the X-Prize, and has entered Google's Lunar X-Prize to retrieve a bit of the moon. More practically, the company has been testing engines in the Mojave desert, but the TubeSat launches planned for next year will be the first time the company has flown a bird, even a small one. ®
