ARISSat-1 02.55

Good signals from ARISSat-1 with transistion from eclipse to sunlight here this morning. Apx. 6 second spin period puts deep nulls in transmitted signal. - Not sure if this is due to linear polarisation of my receive antenna or blockage from spacecraft. Managed to capture just 3 tlm frames and '2 Kursk frames' . (mission time 29997-30018) However, software forwarded zero frames via internet (?). If recording to a .wav file, CW positioned to be 500Hz seems to work well. Battery voltage around 33V status - charging. Thanks David G0MRF

Let's redirect our energy
by E. Michael McCardel 04 Aug '11

04 Aug '11

Gould touches on something I haven't heard mentioned here, "...potential for STEM education." STEM = Science, Technology, Engineering, and Mathematics. It is what is driving education and schools are hungry for community involvement from people who can present projects that help the schools meet STEM education standards. (see stemeducationcoalition.org) Perhaps we should address the impact ARISSat-1 should have on education and the potential of introducing what we do to large amount of young minds. Instead bitching about what has gone wrong, should we redirect our collective energies contacting teachers and local school officials and explaining the educational impact of ARRISat-1, the help them setting up an antenna receiver and installing software. Engage the students. Show them what a great hobby we have and follow-up in getting them more involved. We have a golden opportunity that worth more than 100 grid squares contacts via the transponder. Something I consider more valuable than the cost of deploying this thing, Young Minds. We are lacking dreamers in this age. Here is our chance to create some. Hmmm, maybe one of these kids who get involved will be become our best ally when they go to space.

Hello everyone and it is time again for the Hudson Valley Satcom Group Net this evening on Echolink N2EYH-L and the Mt Beacon Repeater 146.970 pl 100. We will be talking about the deployment of Arrisat-1. Please bring your reports of hearing our newest satellite. Hope to hear you there.73 Gary wa2aqh

ARISSat-1 in SATPC32
by Alan P. Biddle 04 Aug '11

04 Aug '11

Hi, The deployment of ARRISat-1 is approaching. Here is a collection of data on the various modes for use in configuring SATPC32. Note that you will need to tweak the sideband frequencies slightly to account for rig calibration and other issues, as usual, but these should be close. You can paste these in the DOPPLER.SQF file, but before you do, please read on! ARISSat-1,145918.5,0,USB,,,0,0,BPSK/CW-2 ARISSat-1,145950.0,0,FM,,,0,0,VOICE/SSTV ARISSat-1,145930.0,435750.0,USB,LSB,REV,0,0,XPDR ARISSat-1,145938.5,0,USB,,,0,0,CW-1 Since ARISSat-1 will be deployed by a gentle push from the ISS by Cosmonauts, the ISS Keps will be good until separate Keps are released by Space Track. One way to handle the transition is to change the Doppler information slightly: ISS,145918.5,0,USB,,,0,0,BPSK/CW-2 ISS,145950.0,0,FM,,,0,0,VOICE/SSTV ISS,145930.0,435750.0,USB,LSB,REV,0,0,XPDR ISS,145938.5,0,USB,,,0,0,CW-1 Paste the ARISSat-1 data as desired, and also paste the ISS version of the data into the DOPPLER.SQF file after the regular ISS data. For the final test aboard the ISS, and initially after deployment, select ISS tracking, and then select the desired ARRISat-1 frequency data at the end of the list in the CAT window. After the ISS and ARISSat-1 are far enough apart that independent Keps are available, you can begin using ARISSat-1 as a separate object by adding it to the objects you track in the Satellites menu window. The satellite may be identified as ARISSat-1, but may well have some other designation which will be reported. If it is not ARRISat-1, then change the name in the first group above to that used in the Keps. They must agree exactly for SATPC32 to match the Doppler data with the satellite. (You can also use the AmsatNames.txt file, which is covered in the SATPC32 documentation.) You can then delete the extra ISS data if you wish. They won't hurt anything, but it will clean up the ISS CAT window. 73s, Alan WA4SCA

Keps for ARISSat-1?
by Mike Ryan 04 Aug '11

04 Aug '11

Hello, Are there keps for this bird yet? So far I’ve been listening using the ISS keps in SATPC32 but eventually this wont work. What will its official designation in the downloadable keps files be? Also, do we have a “final answer” on the UHF side? Is there an antenna or not? Mike WB1AAT

ARISSat-1 13:59 UTC pass over Florida
by n4csitwo＠bellsouth.net 04 Aug '11

Great pass. The first I've heard out of safe mode. Solid, full quieting using just an Arrow ant. and HT. Heard 3 messages, 2-SSTV frames, 2 or 3 voice tlm. Should be great for schools, etc. Yeah!

I am finding out who has a Mac and who doesn't (grin) ... sorry about the too-long filenames with weird characters. Here's a "better" more-accessible link to the photo gallery cited earlier. http://web.me.com/clintbradford/k6lcs/EVA29-1.html Clint Bradford 909-241-7666
