  • GPS: Galileo reception possible on Kiwi? [working as of v1.178]

    jksjks
    The recent addition of the QZSS sats (Asia/Oceania reception only) increases the percentage of time enough sats are available for fixes (minimum 4 sats required). This is especially true for GPS antennas that don't have a full view of the sky (i.e. shadowed by terrain or buildings). It certainly made a big difference at my NZ location. Since the Galileo E1 signal transmits on a frequency compatible with the Kiwi the question has been asked if it can also be received. It has worldwide reception and so would be very helpful.

    I think the majority of Kiwi owners struggle just to get the supplied antenna near a window, let alone outside and up high. Anything we can do to increase the percentage of Kiwis with functioning GPS would be very useful (e.g. more candidate Kiwis to participate in direction finding experiments). Plus they benefit from automatic, accurate frequency calibration of the SDR.

    I don't know much about HF-DF / triangulation, but fortunately we have a Kiwi user that does. He's already got it working! See: http://hcab14.blogspot.com

  • QZSS Support [GPS, added in v1.170]

    I have recently moved to a new location where I have a limited view of the sky. Either blocked by other apartment buildings or a nearby (hopefully inactive) volcanic cone. The addition of the QZ sats really improves the amount of time I have enough sats in view (4) to compute location fixes.

    Well, that was easier than I thought.

    I'm tracking PRN 194 and 195 no problem from here in New Zealand (QZS-2 and -4 respectively). Subframes are decoding and the software is flagging them as good. I have a little work to do to make the az/el display work correctly for them.

  • Some things I have noticed [problems with a large DX/label database]

    jksjks
    Today's release, v1.168, has some improvements to the speed of dx labels during normal operation. Please let me know how the changes work for you. Problems during on-screen label editing are still being considered.
