Asset tracker GPS bad performance?

So I’m trying the Asset tracker out, and I put in a refresh interval of 1 min, and drove around.

First it took like 3 min minimum to get a GPS lock. Then it started reporting.

First location: 1.000003,21.410112
Which is in the Democratic Republic of Congo.

Second location was about 4 meters off, which is to be expected with GPS:
42.002392,21.404993

Third location is somewhere in Chad, Latitude is off:
17.000134,21.395967

Fourth location is Chad again, and the last location was finally back in my country. I gave up after that.

Why is it having such an issue getting a GPS lock and getting a coordinate somewhere within the same continent?

Hi @r0b0tn1k,

GPS is tricky! You’re getting very weak signals from very far away that depend on precise timing and a really good view of the sky and horizon.

Make sure your GPS device is laying flat on its back, with its antenna pointed up at the sky, or use an external antenna. Cold starts of 3-5 minutes are normal, use a coin cell battery for warm or hot starts to keep the GPS memory fresh.

And make sure you check the fix quality and number of satellites you’re getting back from the GPS. It has a good idea of how accurate the result is that it’s giving you, so you can use that to avoid accidentally warping hundreds of miles away. :slight_smile:

Thanks,
David
