Sneak Preview

Filed under: Uncategorized — sbasuita @ 21:24

Hi all. First of all, I would like to say today has been really awesome – things couldn’t have gone better with our first launch. Anyway, we’re pretty tired at the moment and have got almost 3,000 pictures to organise. A big writeup will be coming, but in the meantime here’s a nice ‘sneak preview’ from ~30km altitude…


The Payload data (and an annotated decode of what it means) for the second that this photo was taken is pasted below
$$A1,10210,14:12:27,52.240798,000.540368,29694,0000,07,2B42ABFF,45*15 | 14:12:27: N52.240798 E000.540368 29694M (07 satellites), Internal: 33.0'C, External: 0.5'C

  1. Congratulations – judging by this one, you obviously got great pics, and a great altitude (just a km or two off the UK record, I think).

  2. Great picture, was able to track you after about 6000m in altitude although i couldnt get flight digi to work, spent some time this evening configuring, here’s to the next flight , this time im ready!!! Well done.

  3. Congratulations on a job well done, missed the first 30mins but tracked it to the end. Very good signal in Ipswich up to S6 during descent, also easily copyable on FT817 and whip indoors at times.
    Main rig FT 847 and V-2000 vertical, notable that the signal was strongest at 2500m during descent as at full height it was off the top of the main lobe.
    Could not decode the text using normal RTTY program, will use yours ‘next time’ :-)
    Also received by 2E0RBD who is very interested in the project, what a thing to tell your science teacher about on Tuesday.

  4. Well done! What a superb result from your first launch :) I can’t wait to see more of the pictures..

    I actually logged on to attempt to track Icarus, but when that didn’t happen I checked back every 1/2 hour or so and actually was looking at the tracking screen when you launched. I occasionally had a ghost of a signal from about 8000m and an easily audible one from about 15000m, but I never managed to decode anything – I’ll read up a bit and hope to do better next time.

  5. Brilliant job! Good signal here in Twickenham – my first successful attempt to receive a balloon payload. Good decodes here but I obviously have a problem with dl-fldigi in getting the data to the server. 33116m – looking forward to seeing the pictures!
