Received ESTCube-1 Telemetry

ESTCube-1 ModelI had a couple of nice ESTCube-1 passes this day and I gave it a try.

I used my FUNcube Dongle Pro+, SDRSharp, DDE Plugin and SatPC32. To decode the signals I used my sound card modem setup. This gave me a total of 277 frames that I tried to decode with the ESTCube-1 FM decode software from DK3WN.

When I used this software it also created a image.raw file but I am unable to convert it into an image. The kiss file can be downloaded at the following location so if somebody else can give it a try, be my guest.

  1. Hi Jan, try IfanView in 24bpp 640*480 mode rgb you will see the beginnings of an image,I’ve had not much better success with my other downloads from Estcube, hopefully someone else has a better solution ,maybe Colin Hurst knows how to do it ,he produced some good image software for some of the early hamsats. Best of luck….

  2. Hi Dave,

    Thanks for the reply. I will give that a try. I did some experiments with ufraw on a GNU/Linux system but this command line tool did detect any data. Maybe the settings 24bpp 640×480 as input for ufraw will give some output that is readable.

    • Hi Dave,

      DK3WN has made a new ESTCube-1 decoder version that has the ability to decode the image file. One thing that you have to keep in mind, it takes two days for the Cubesat to download a complete image. This was shared with the community at the Amsat-UK Colloquium.
