  1. Is there a Linux version of this software?

  3. Is the telemetry encoding format documented anywhere? It appears it’s using the concatenated Reed-Solomon/Viterbi scheme I designed for AO-40, and I wish I had known because much of my AO-40 design was forced by the limitations of that particular spacecraft and particularly the damage it experienced. High and low altitude satellites are generally also very different problems requiring different solutions; high altitude satellites have long passes, weak signals and little fading unless it’s a property of the antennas (as on AO-40). Satellites in LEO have short passes, much stronger signals and heavy fading due to tumbling and rapidly changing aspect angles.

      I’d also be interested in the encoding format, so that I can compare the funcube encoding with other schemes such as LDPC or Reed-Solomon codes. For the ‘normal’ Cubesat link, these codes are probably much more suitable.

      I have developed a channel model for the cubesat of my university a few months ago and I’d love to verify it with funcube telemetry data. So, if the team could release the source code or at least publish a document that explains the encoding in great detail, that’d be great.

      @Phil Karn: Have you ever experienced fading effects due to multipath propagation? We have received roughly about 2000 telemetry frames of funcube-1, most of them severely damaged. Since our antennas are cross-polarized yagis, I rule out spin fading.

        Hi Nicolas, could you contact me directly about LDPC coding?

        I would not rule out spin fading simply because you have cross-polarized antennas. You are probably seeing nulls in the spacecraft antenna. Many cubesats use simple linear whips, so you lose signal when the antenna axis sweeps past you. Multipath is a severe problem in terrestrial communications but it is relatively minor with satellites except at very low elevation angles. I designed the telemetry schemes for AO-40/73, ARISSAT-1 and FOX-1, and all make heavy use of interleaving to ride through fades. But interleaving adds delay, and nobody can ever tell me the maximum length of a fade, so I have to pick a number.

        I also use noncoherent modulation as it is more tolerant of fading at the cost of several dB worse performance on a weak non-fading channel. When an antenna null sweeps past you the carrier phase usually flips, and that makes it difficult to track coherently. I used DBPSK on AO-40 and ARISSAT-1 and data under voice on the FM satellite FOX-1.

    And what about a RPI dashboard version?. It may be greath to capture and forward telemetry without leaveng my Pc on all day.!! and

    I have tried to get Nayif-1 telemetry successfully, but the Dashboard shows error sending the data.
    I realized the Dashboard is receiving the message “Unathorized” from Nayif Warehouse site (can see it through network protocol analyzer).
    The Auth Code I have received works fine for Funcube Dashboard data.
    Is the warehouse url for Funcube the same for Nayif? Am I missing something?

    • g3vzv permalink

      Hi Luiz, Yes the warehouse address http://data.funcube.org.uk is the same for both FUNcube-1 and Nayif. Just make sure that there are no no leading spaces…I have suffered with that before! Let us know how you get on and thanks in advance for your data. 73 Graham G3VZV

      • Luiz Tresso permalink

        Hi Graham. I have checked the auth code/site ID and it seems to be ok (found no leading spaces or special characters).
        The warehouse website still sending unathorized message.
