able to receive beacon telemetry transmissions from the JAISAT-1 satellite.
by Tanan Rangseeprom 28 Jun '19

Dear AMSAT Member. We would like to inform AMSAT members that they should be able to receive beacon telemetry transmissions from the JAISAT-1 satellite amateur radio of Thailand by Radio Amateur Society of Thailand (RAST). for detail with picture to install all satellites to fairing of rocket see detail as link: https://www.roscosmos.ru/26486/ and https://www.roscosmos.ru/26491/ and video https://www.youtube.com/watch?v=klXEGKKTlFs) and animation video https://www.youtube.com/watch?v=xcUhJMU4mHA&t=10s Which is scheduled for launching on July 5, 2019 by a Soyuz 2.1 rocket at 05.41 UTC together with the Meteor M N2-2 satellite and along with a total of 34 satellites from 12 countries. There is a telemetry beacon with a downlink on 435.325 MHz in accordance with the details from the IARU satellite co-ordinator according to the following link: http://www.amsatuk.me.uk/iaru/finished_detail.php?serialnum=521 The telemetry signal formet is 4k8 GMSK Mobitex (CMX990 Mobitex Format) as is detailed in the link below: http://www.d-star.one/downloads/D-Star%20ONE%20telemetry%20frame%20format.p… Example of signals in same this format can be found with the the reception of signals from the D-STAR ONE Sparrow and D-STAR ONE iSAT satellite http://dk3wn.info/blog/satelliten/d-star-one/ on the frequency of 435.70 MHz with YouTube videos that at the following links: https://www.youtube.com/watch?v=UAjPOJDbHdA and https://www.youtube.com/watch?v=Rm_NS3Prz9U This is from the following link that you can download for decode: http://uz7.ho.ua/packetradio.htm and http://www.dk3wn.info/files/dstar_one.zip All amateur radio operators capable of receiving signals from the JAISAT-1 satellite are invited to send the data by email to jaisatonetele(a)gmail.com and the Radio Amateur Society of Thailand will have a SWL card to confirm reception to everyone. Sincerely and with respect. 73 de Tanan Rangseeprom, HS1JAN Project Manager of JAISAT-1

TLE Elements for PSAT2
by Robert Bruninga 28 Jun '19

28 Jun '19

I've been using object 44348 but PSAT2 is arriving maybe 2 or 3 minutes earler Steve Dimse guesses 44357 below SATNOGS guesses 44354 or 44355 and thinks they see BRICSAT2 9600 bd on 437.600 Bob -----Original Message----- From: aprssig <aprssig-bounces(a)lists.tapr.org> On Behalf Of Steve Dimse Sent: Thursday, June 27, 2019 10:54 PM To: Max Harper via aprssig <aprssig(a)lists.tapr.org> Subject: Re: [aprssig] Designation for PSAT2 > On Jun 25, 2019, at 8:33 AM, Max Harper via aprssig <aprssig(a)lists.tapr.org> wrote: > > Yes, the keplerian elements or TLE is what I'm looking for.

Watching when IGates receive the beacons, my wild-ass guess is PSAT2 is 19-036U, but it could be R, S, or T, those are still pretty close together. Here is the latest TLE for 19036U 1 44357U 19036U 19178.41227610 .00060436 00000-0 94415-3 0 9996 2 44357 28.5325 187.1376 0389997 127.0282 350.5130 14.97361557 296 NORAD is releasing new keps for these several times a day as they refine them, so even if this is the right bird expect these to be worthless in a couple days.

Satpc32
by Bruce 28 Jun '19

28 Jun '19

I bought a Yaesu G5500 to use during field day this year, we got tired of the arm strong rotor. This is the first time I have used SATPC32 for anything more than AOS-LOS predictions. I still moved the rotor by hand. Have not been able to get the Yaesu cable built to have the LVB tracker control the rotor. May work on that for next year. Used the ICOM IC-9100 and a laptop this year. It worked great to set the frequency for the FM satellites but was horrible for any SSB satellite. I can find myself with the computer turned off. When I tried to use Satpc32, it would jump to somewhere in the passband and no matter how i tried to adjust the radio to find myself, satpc32 had a mind of its own. So, never made an SSB contact. Of course it is more fun to do this during field day with everyone watching. So what is the secret for making Satpc32 see where you have found the sweet spot on the up and down link when you click CAT control instead of doing what it wants? I would have thought it would read the settings from the radio and go from there. After all, it takes me a few seconds to find myself and really easier to adjust for Doppler manually. I wanted to give the automated feature a go for those watching. 73...bruce -- Bruce Paige, KK5DO AMSAT Director Contests and Awards AMSAT Board Member 2016-2020 ARRL Awards Field Checker (WAS, 5BWAS, VUCC), VE Houston AMSAT Net - Wed 0100z on Echolink - Conference *AMSAT* Also live streaming MP3 at http://www.amsatnet.com Podcast at http://www.amsatnet.com/podcast.xml or iTunes Latest satellite news on the ARRL Audio News http://www.arrl.org AMSAT on Twitter http://www.twitter.com/amsat

PSAT2 simple tracking for wilderness mobiles
by Robert Bruninga 27 Jun '19

27 Jun '19

You don't need no stinkin' computer... I updated my Mobile LEO tracking site to show graphically how PSAT2 orbit works. http://aprs.org/MobileLEOtracking.html Easy to remember. 5 minutes later per day, but a new orbit an hour and a half earlier every other day. (This is approximate... time will tell... might change as we see the effect of the elliptical orbit) If you are in the wilderness, just monitor 145.825 and when you hear PSAT2, then you can easily guess all orbits in the future... Bob, WB4APR -----Original Message----- From: Robert Bruninga <bruninga(a)usna.edu> Sent: Thursday, June 27, 2019 12:13 PM To: 'amsat bb' <amsat-bb(a)amsat.org> Cc: Robert Bruninga <bruninga(a)usna.edu>; 'Steve Dimse' <sdimse(a)gmail.com> Subject: PSAT2 is coming to Northern Latitudes!! PSAT2 is coming to the Northern hemisphere! After reviewing the orbit, it is somewhat time synchronous, meaning each orbit time (at mid northern latitudes) is just 5 minutes later each night. But then a NEW earlier orbit appears 90 minutes earlier every other day. So, by the 4th of july, one week from now, PSAT2 first pass will be as early as 4 PM local time... (in the Northern Hemisphere mid latitudes) And the Apogee moves rapidly, In just two weeks, Apogee will be over the northern hemisphere giving higher latitudes much better access. At launch it was the middle of the night and perigee was in the Northern hemisphere making it only visible for lower latitudes. So things will improve for Northern Hemisphere .... (and then two weeks get worse, etc)... 24 Hour telemetry plots (links to FINDU.COM) are now available on the http://aprs.org/psat2.html page. Bob, WB4APR

AO-85 update
by Andrew Glasbrenner 27 Jun '19

27 Jun '19

At about 2105UTC today I disabled the auto Safe mode function on AO-85, and turned the transponder on. After verifying it would drop with inactivity, a few QSOs were made before LOS. Currently, the battery voltage is very low and it looks like we have a cell about to give up the ghost. Please do not use the satellite while it is in eclipse, even if you hear it OK. We are not sure what will be usable if and when this cell fails completely. In the meantime, reports to -bb are welcome and helpful. Thanks and 73, Drew KO4MA AMSAT VP Operations
