uBlox ZED-F9P series of GPS is their new and first multiband GPS series. Until now we have all used mostly their M8 series which was already very good GPS modules. I have watched Tridge’s blog on his own very technically detailed testing which triggered me to do this comparison between F9 and M8 series of uBlox GPSs.
I have so far used M8 series GPSs on all of my UAV builds so far with great satisfaction.
The fact F9 series are multiband GPSs, there should be a good improvement on performance (precision, speed of acquisition)
To test it out, I connected an Ardusimple F9 GPS eval board to a Pixhawk1 board on GPS port 1. I simultaneously connected a M8 GPS on GPS port 2.
Both antenna were placed in the exact same location and orientation, inside a a three stories home. The idea is to see in a difficult non clear sky view how these two uBlox modules compare.
The results are quite self explanatory… as shown in the video.
