Hello AMSAT-ers The University of Louisiana has a slot on a ULA mission to GTO launch to GTO for a 1u. WE are asking the community what payload should we fly, how to mitigate the radiation and who wants to help the students? http://www.ulalaunch.com/ula-announces-2016-cubesat-stem-winners.aspx?title= United+Launch+Alliance+Announces+CubeSat+STEM+Education+Program+Winners <http://www.ulalaunch.com/ula-announces-2016-cubesat-stem-winners.aspx?title =United+Launch+Alliance+Announces+CubeSat+STEM+Education+Program+Winners&Cat egory=News> &Category=News 73's and see you on the baot nick k5qxj

Hi, I am thinking along the lines of K.I.S.S - a simple "bent pipe" linear transponder, with as little to go wrong as possible (the bird will be in GTO for a very long time). Power and link budget permitting (eg a 5 GHz / 10 GHz machine), a wideband transponder would permit ranging experiments, high speed data and video modes in addition to CW & SSB... Can the attitude of a 1U cubesat in GTO be passively stabilised (gravity gradient?) to keep the antennae pointing towards nadir? Is a microprocessor (or any digital logic) strictly required? simply having the transponder run whenever the arming pin is out (pulled by ejection from the cubesat canister) and the DC volts are high enough, would eliminate the need for a rad-hard processor. As far as I am aware, the RF circuits in a "rock locked" (no PLL) linear transponder are not as prone to SEU induced latchup as digital circuitry. 73 ZL2WRW Ross Whenmouth

Re: [amsat-bb] Outernet L-Band now carries AMSAT and ARISS weeklybulletins

> It might be useful to start... each file with the date of publication I agree. I guess I can remember to add a date when I manually edit it down to under 6K as requested by the Outernet Folks. And the other NEAT application of an OUternet WiFi hotspot at ham events, such as hamfests, or Public Service events or scouting events or anything where Ham Radio is helping to provide communications is that this Outernet WiFi hot spot not only serves all the Outernet (L-Band delivered) files to everyone in the local WiFi area, but also the local SYSOP can upload his own files in real time to the server. Imagine if he maintains the latest Agenda, Schedule, Plans, Reports, Pass times, Lost-N-found, and any other important real-time files of interest to anyone in the area with a smart phone or tablet! Remember, this Outerlink Hotspot and Geostationary satellite feed is just a stand-alone cigarbox size piece of hardware powered by a small battery. What could be easier and have so much potential...

> The University of Louisiana has a slot ... to GTO for a 1u. > WE are asking the community what payload should we fly... You could always fly an APRS digipeater. PSAT works well at LEO, but is only 300 mW. Our next 1U APRS satellite will have a 2W transmitter and will be quite strong horizon to horizon to an HT on the ground. But if you raise the cubesat TX power to 4W, and use Oscar class stations running 50w instead of 5W HT's on the ground, you can pick up 23 dB more performance which is exactly what you need to operate to GTO at 35,000km. The problem is the TX duty cycle. All of the APRS satellites operate with a quite low TX duty cycle because Hams only cover about 10% of the Earth's surface so the average transmitter power is low. On GTO, half the users in the world can see it half the time and if they all start banging it with chatter, then a 1U wont have the average power. Does your GTO remain attached to a large spacecraft? Does it have more than the average 1 Watt Solar power that a cubesat gets? If so, then the duty cycle might not be a problem. ON THE OTHER HAND, every APRS digipeater has a DUPE-WAIT setting that is normally 30 seconds for mobiles to prohibit duplicating packets. You could extend this to X miuntes to make sure no one tries to get through more than one packet per X minutes. Or you can think of otherways to control the user load. Again, I am assuming 2m on 145.825 MHz. Although that is full of existing users trying to hit the PCSAT, PSAT and ISS, no users without an OSCAR class station and 50W will even be heard out there at GEO. SO that is a good way to share the channel. Unless I overlooked something, I think it could work. It would be a great emergency response and disaster preparedness link. For low duty cycle comms into and out of an area. You could build the whole system includeing a 10W PA using the parts from a Byonics Microtrak TT4. That is what we use (without the 10W PA) for our PSAT-2 and follow-on designs. See http://aprs.org/psat-2.html Bob, Wb4APR
