GPS signal quality

[Bernhard]

Hello,

we have built a custom nRF9160 board with different populations for the GPS antenna,
now we would like to do some tests to find out which variant offers the best signal quality.

For LTE antenna there are different AT commands available for such purposes,
but I was not able to find similar ones for the GPS antenna.
Also other methods (like measuring TTFF) seem not really useful since for
GPS such values strongly depend on environmental influences.

Is there any preferred method which can be easily (without full EMC equipment) performed?

Thank you!

Best regards,
Bernhard

Hello Bernhard,

You will have several GPS antennas on your custom board?

To test the Signal to Noise Ratio, we have command %XRFTEST (https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/production_test/xrftest_gps_snr.html?cp=2_1_10_3) that you can try. You may try this for each GPS antenna on your custom bord.

Thanks.
