The 0/6 sats has me concerned that it’s not able to make a fix on any known satellites. My next step would be to place the device in the most open southern-facing spot possible - making sure the GPS antenna is securely connected and there is no possible interference.
Are you completely powering-down the Pi in between runs? If so, FYI the Notecard will lose any satellite data it has stored, so a cold start will require additional time to get a fix.
This thread may be helpful as well - including my next suggestion, which would be to get a GPS trace log. See the instructions here for initiating a trace, and note you’ll want to use this argument with your card.trace call: "trace":"+gpsmax".
We will figure this out!
