JARL Translator needed for FO-29 status
by Alan Thoren 30 Apr '07

30 Apr '07

Hi to the group. Rather than speculate on the status of FO-29, perhaps someone with some Japanese/English ability could monitor the Japanese pages of the JARL site, http://www.jarl.or.jp/index.html as the English pages are not in sync with the Japanese. Specifically this page that may be FO-29 related as it has a FO-29 graphic and is dated 23 Apr 07 http://www.jarl.or.jp/Japanese/2_Joho/2007_news-4.htm#0423 I have not been successful installing the Japanese language pack into IE7. Even then, I don't know if a cut and paste into Babelfish http://babelfish.altavista.com/ would give us anything understandable. 73, Alan VE4YZ AMSAT 35968 <http://www.mts.net/~ve4wsc/> http://www.mts.net/~ve4wsc/ AMSAT A-485

online translation page for JARL FO-29 web pages
by DeYoung James 30 Apr '07

30 Apr '07

Greetings, The following tool seems to do a decent job at translation of the JARL FO-29 "news" page to English. http://www.google.com/language_tools My interpretation is the JARL FO-29 group wants any captured telemetry from just before the failure to help them figure out what is wrong. Also, they are looking for any reception reports since it has gone "off-the-air" to assist them in determining if the TX power is just extremely low (remember Suitsat-1!) or really off. Please, if you have any verified information that will help them recover FO-29 send it to them. 73, KG4QWC __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!

Then look up the individual satellite project's home page to find their operating parameters: orbit type, min/max range, frequencies, power output and antennas. Once you have the particulars for the satellites you wish to track, then you need to calculate path-link performance in order to determine your ground station antenna, receiver and transmitter requirements. This last part is probably the biggest problem for most prospective operators. In the past I (and others) have written some programs to analyze performance of certain satellites. Most recently I did one for receiving the Mars Reconnaissance Orbiter, but this can be used (with a few modifications) for making path-link calculations for any satellite; here is the link to the Excel spreadsheet: http://www.kl7uw.com/MROCalc.xls It is not very fancy and has no macros, but it will provide one with an idea of what they need on the ground for receiving. To modify this program to suit another satellite you will need to turn off "protection" by clicking "tools", "protection", and select "unprotect sheet". In order for me (or others) to produce a program for predicting satellite performance (path-link analysis), we will need to know certain satellite parameters. I have not investigated to see if enough of these have been established for P3E or Eagle, for one to produce a specific program. A completely generic program can be done, which then would place the issue of gathering these parameters in the hands of the user. But I guess that such a generic program would have some value even if some items were "guess-itmates"! Once you have determined a set of antenna gain, receiver noise figure, and transmitter power requirements for your ground station, then it becomes a process of designing a station to accomplish them: right combos of radios, converters, preamps, cables, antennas, and tracking. I know that many wish a complete paper or article suggesting specific equipment and configurations to accomplish this. But at this point I suspect that too many things are still subject to change or still in design, to "nail down". 73, Ed - KL7UW ====================================== BP40IQ 50-MHz - 10-GHz www.kl7uw.com 144-EME: FT-847, mgf-1801, 4x-xpol-20, 185w DUBUS Magazine USA Rep dubususa(a)hotmail.com ======================================

Responding to my own query, because I always post too soon, you can cut and paste the JARL URL's into the Babelfish link below and it will do a full web page translation. Bottom line they are still investigating, collecting information and but want feed back on any signal heard. However, I hesitate to give the email address for the feedback as it may not have been translated correctly. _____ From: Alan Thoren [mailto:[email protected]] Sent: April 29, 2007 10:04 PM To: 'amsat-bb(a)amsat.org' Subject: JARL Translator needed for FO-29 status Hi to the group.
