AO-91 and RS-44 not functioning?
by hamdan＠ix.netcom.com 18 Apr '23

Dear Folks: Today, neither AO-91 nor RS-44 seemed to be functioning. To be fair, I could barely hear my CW transmission on RS-44, so I suppose its transponder is functioning, albeit not well. I can understand AO-91 going out due to its battery issues, but RS-44 on the same day? Is it possible that the problem is with my setup? Thanks for any help you can give me. 73 de Bernie, KF0QS

It was shareware. a computer guy came to a ham event, and had lots of programs for commodore, and he just happened to have a tracking program. I do remember mailing a couple bucks to the program author. Kind of brings back memories. It worked good and I used it until I got my first PC, then I bought InstantTrack. It came in the mail from Amsat on two floppies with a freeware de-compression program. Still use InstantTrack to this day for antenna control on a windows 98 computer. I think InstantTrack is one of the best tracking programs ever written, with all the information it can give you besides just tracking satellites. KB7ADL

Of course nowadays there are modern verbose style formats available: https://celestrak.org/NORAD/elements/gp.php?CATNR=25544&FORMAT=KVN https://celestrak.org/NORAD/elements/gp.php?CATNR=25544&FORMAT=JSON-PRETTY 73, Nico PA0DLO On 18-04-2023 20:42, Paul Stoetzer via AMSAT-BB wrote: > Copies of QuikTrak by Bob McGwier, N4HY, for both the Commodore 64/128 > and Apple II are available at > https://www.amsat.org/flashback-friday-satellite-tracking-with-quiktrak-for… > > > The disk image files can be used in emulators or written to real > floppy disks / modern floppy emulators and run on real hardware.

What commodore program did you use? My elmer had a cool one, and I traded a commodore 64 for an RC car because I thought it was so cool. Well guess what, I just picked up that computer for my parent's house 35 years later and it still works! I brought it to school for the kids to see. I found one on a dead link from an amsat news post, but that is not the same program. I was able to get running on a simulator, and I could tell that it was not the same app. I distinctly remember lots of colors. I am waiting for fresh floppies and a raspberry Pi hat that emulates a 1541 drive as all my floppies were dead as this thing has been in the garage for many of those 35 years.

Neither element set format encodes the century of the element set, so I suspect that whatever math is being done in the program to determine the age of the element set will fail in either case. You can test this hypothesis by making up a verbose element set manually with your favorite text editor. Decode two line element sets with the following key: 1 AAAAAU 00 0 0 BBBBB.BBBBBBBB .CCCCCCCC 00000-0 00000-0 0 DDDZ 2 AAAAA EEE.EEEE FFF.FFFF GGGGGGG HHH.HHHH III.IIII JJ.JJJJJJJJKKKKKZ KEY: A-CATALOGNUM B-EPOCHTIME C-DECAY D-ELSETNUM E-INCLINATION F-RAAN G-ECCENTRICITY H-ARGPERIGEE I-MNANOM J-MNMOTION K-ORBITNUM Z-CHECKSUM For more detail see www.amsat.org/keplerian-elements-formats/ If your trial verbose file works OK, it might be worth it to have one of the high school kids write a script to convert from TLE to verbose - it is a pretty straightforward exercise in text manipulation. The TLE format is actually the older format. AMSAT came up with the verbose format in order to facilitate distribution on voice networks. I fondly remember copying them as read by Rip, WA2LQQ on the weekly Tuesday night75 meter net. At the time I was not really all that fond of it since a static crash at the wrong time could wipe out a critical digit and render an entire element set useless. But it was the only practical means I had to obtain them as a broke high school student in the 1980's, at least until I discovered that the government would mail them to me once a week if I asked nicely :-) de KM1P Joe

I am playing around with FBB (Old packet BBS) and it has a satellite tracking server in it which I think is super cool (and even have high school kids interested in the project). I am not sure if it is Y2K compliant, the keps are updated through BBS posts and the updater is not happy with the Nasa TLE format that they come in presently. It has a flag for them, but it complains that fresh keps are too old. I am going to try passing some though that are of the older verbose variety (Old AMSAT style). Is there a source for these or at least some Perl or Python script to convert them? Thanks, Chris KQ6UP DM14ia -- Thanks, Chris Maness

(***) https://www.amsat.org/amsat/ariss/news/Successful_ARISS_schools.rtf ####################################################################################################################################### Comments on making general contacts I have been seeing a lot of traffic on Facebook and I suspect on other social media sites with people asking why they are not hearing the crew make general contacts. First off the crew is very busy on the ISS and they simply may not have the time to just pick up the microphone and talk. Also, one needs to be aware of their normal daily schedule. I have listed below the constraints that we at ARISS have to follow in order to schedule the school contacts. Hopefully this will help you better schedule your opportunities. Typical daily schedule Wakeup to Workday start= 1.5 hours Workday start to Workday end=12 hours Workday end to Sleep= 2 hours Sleep to wakeup= 8.5 hours The crew's usual waking period is 0730 - 1930 UTC. The most common times to find a crew member making casual periods are about one hour after waking and before sleeping, when they have personal time. They're usually free most of the weekend, as well. SSTV events are not that often. So please check out https://www.ariss.org/ for the latest information or watch for the ARISS announcements. And don’t forget that the packet system is active. As always, if there is an EVA, a docking, or an undocking; the ARISS radios are turned off as part of the safety protocol. The latest information on the operation mode can be found at https://www.ariss.org/current-status-of-iss-stations.html The latest list of frequencies in use can be found at https://www.ariss.org/contact-the-iss.html ######################################################################################################################################## A multi-point telebridge contact means that each student will be on the telebridge from their own home. **************************************************************************************************************************************** ARISS is very aware of the impact that COVID-19 is having on schools and the public in general. As such, we may have last minute cancellations or postponements of school contacts. As always, I will try to provide everyone with near-real-time updates. Watch for future COVID-19 related announcements at https://www.ariss.org/ The following schools have now been postponed or cancelled due to COVID-19: Postponed: No new schools Cancelled: No new schools **************************************************************************************************************************************** The ARISS webpage is at https://www.ariss.org/ Note that there are links to other ARISS websites from this site.
