If you have a dual frequency receiver (L1/L2), then the ionospheric error is corrected for. These are very common these days, so probably not the reason.

- tamimio 3y agoWe had similar anomalies with tri-bands gnss drone before (L1, L2, and L5) with multi constellations support, I even remember before we had similar issues with an RTK enabled system. It is puzzling because the next day we would bring the sane drone and systems, and as of nothing happened, and since the problem solve itself we never bothered to investigate more.
- dfox 3y agoThat seems like ground based interference. Today a lot of stuff, including components of the drone itself, can be unintentional L-band radiators. Getting what is probably the cheapest tier of spectrum analyzer and investigating that behavior seems somewhat prudent.
- jrockway 3y agoIf it's obvious a spectrum analyzer will help, but GPS signals are very weak and you won't be able to see anything without special equipment. (-125 dBm at the Earth's surface; that's ATTOwatts of power.)
