Do not show up on TDOA list

I think I have setup my Kiwi correctly to support TDOA. However I never show up on the map. Is there something special that needs to be done to show up on the map?

    Very interesting. All of a sudden I show up. 1/2 and hour ago I wasn't there.

    Very strange.

    And now I am off the map again. I was running a test and it complained of that I wasn't getting GPS fixes. Yet I am constantly getting good GPS fixes.

    Not sure where to look.

    Looks like I am not getting enough "GPS Fixes per Minute" to qualify. My GPS fixes per minute is low. I guess I need a way to extend my GPS antenna up higher so I get man more fixes per minute.

    Hi Jim,

    Take a look at http://wa6our.ddns.net:8073/status The parameter "fixes_min" is what the TDoA extension is looking at (it's currently zero). You've had 10k fixes over an uptime of 86700 secs (a little over 1 day). But the "fixes_hr" parameter currently says 55, so that's not so great. Probably your antenna doesn't have a large enough view of the sky and there are times where there are no fixes at all due to < 4 good sats in view (the parameter "gps_good" is the number of sats considered good enough to provide a fix -- it's currently only 2).

    I have acquired a longer cable and plan on moving the GPS antenna higher up on my house. Hopefully it will get a 180 degree view of the sky.

    Placed the antenna in the front yard and it is now showing around 25 fixes per minute. What a difference 20 feet can make. Plans now are to put it on the roof of the house to get an even better view.

    Mine are super low .. I'm in the middle of the house and cable isn't long enough to makeit outside... but I do get a couple sats inside..
