Hi @williamzoe2002,

There is a relatively [long forum thread here](https://discuss.blues.com/t/not-getting-track-qo-notes-after-initial-satellite-fix/1145) that goes through some common GPS-related issues with the Notecard (e.g. make sure the antenna has a clear view of the southern sky, among many other suggestions to help debug).

Please let us know here if you resolve the issue (or if you still need help after reading through the forum).

Thanks,  
Rob

Try initiating your trace with this command:

```auto
{"req":"card.trace", "mode":"on", "trace":"+gpsmax"}

```

Let me know if that works!
