Here's 5 types of GPS were used in the test.
- Flywoo GM8 Mini V2.0
- Beitian BN-220
- Matek M8Q-5883
- Matek M10Q-5883
- BZGNSS BZ-121
The conditions of the experiment are not completely controlled and the number of experiments is extremely insufficient.
Additional experiments may be needed.
What I felt roughly is that the refresh rate is definitely good as the generation is replaced with the M10, and the reception performance seems to be at the level of the wall.
The RTL of GPS rescue in beta 4.4 is not perfect, but it seems to be very good if you check a few things carefully.
You just need to check for a few errors.
- Does the home position indicate well?
- Check if the home point points well when turning the aircraft or changing the nose
- The altimeter seems to have an error sometimes. (There was an error once in the video. It doesn't happen often.)
While the satellite reception rate of the BN220 in the m8 series is good, the home position error seems to be severe, and the refresh rate seems to be slow.
Next time, we will get more reliable test results with more tests and data.
