Regards the record data while manually flying what data do we want to record?
Anything else?
Sensor | Max Update Frequency | Accuracy | Output Resolution |
---|---|---|---|
TeraBee TeraRanger Evo 60m | 240Hz | 40mm below 14m and 1.5% above 14m | 5mm below 14m and 20mm above 14m |
Seeed Studio Grove VL53L0X module | 50Hz | +/- 3% at 5Hz at 1.2m and +/- 5% at 50Hz at 1.2m | |

Regards the record data while manually flying what data do we want to record?
- ToF
- Barometer
- GNSS
Anything else?
That should be sufficient. It would be interesting to record accelerations from the IMU too, if possible. We should look at the missing values too, so let's record unfiltered values.
@pdavid747, can you update the document in this PR using the notes I shared on Teams the other day? We should also include some simulation results in the document.
Main Changes
This is still work in progress. I'm creating this PR to keep everyone in the loop. The objective here is to create a whitepaper on how the kalman filter for altitude estimation. The sensors we want to fuse are (i) the ToF, (ii) the barometer, (iii) the GNSS. They have quite different characterstics (update frequency, precision/accuracy, missing values).
An immediate exercise we need to do is to record sensor data, preferably while flying manually. Do record a video at the same time.
