I have been running experiments with these sensors working for more than 24 hours.
It seems that there’s always the same signals missing from the L2 band.
Running tests from different positions and constellations configurations, we are always missing the same L2 band signals for the exact same satellites. We receive their signals from L1, but not from L2.
Other GNSS receivers with the same configuration are able to receive them, so it is a specific problem of our ZED-F9P.
Has anybody else experienced something similar?
Hi mosphet19!,
That is a weird issue that I have not seen before. You should have no issues picking up L2 band signals with the ZED-F9P. The only thing I can think of off the top of my head is you are decoding the wrong RTCM 3.3 message or are not in the correct mode. The table in section 1.4.2 of the [ZED-F9P Datasheet has a list of the RTCM 3.3 messages the ZED-F9P can decode in RTK and rover mode. That may help you troubleshoot the issue.
If this information does not help solve the problem, can you please elaborate on how you are receiving the data from the ZED-F9P? Are you using it with u-center or the Arduino Library? Are you using a specific port to view the data? If so, which one?](https://cdn.sparkfun.com/assets/8/3/2/b/8/ZED-F9P_Data_Sheet.pdf)
