About this score

Worked out from the flight log between liftoff and 80% of apogee, independent of the angle the altimeter was mounted at in the airframe.

Inclinaison à la fin de combustion (20%) – how close to vertical it left the rod.

Tangage/lacet (30%) and Coning · boost (25%) – how much the nose swung off the rocket's own axis. The main factor.

Rectitude de poussée (15%) – how cleanly the motor pushed along the body.

Spin about the rocket's own axis is not counted against it — a fast, straight spin is stable. The line under the bars shows the raw measurements.

Notes utilisateur

Nano appeared to have run down after flight, but log was recovered after charging for some time. flightinfo.html is blank. Odd that the stats here show charge at 63% post-flight.

Combustion moteur

The dashed line is the combined thrust curve for your motors (data from thrustcurve.org), scaled so its peak matches the recorded acceleration maximum — the shape is meaningful, the absolute level is not (your rocket's weight is unknown).

Just for fun: whichever flight came down closest to 8 m above the launch point (roughly tree height) is the one most likely stuck up a tree.

Paramètres généraux

Ceci est un aperçu des paramètres utilisés pour ce vol. Rendez-vous sur la Rendez-vous sur la page Mes appareils puis Configurer les paramètres..

Pression prévue

Set this to your local forecast pressure at sea level. This will offer you slightly improved accuracty for your flight, although it's not 100% essential every little helps!

Xcweather.co.uk is a decent place to grab pressures from for your location and time.

1013.2 mbar

Détection lancement

This is the altitude above the launch pad altitude where the altimeter will trigger itself into recording / flight mode.

The altimeter keeps a constant average of the pressure while waiting for launch, it uses a simple algorithm and the pre-flight buffers to do this. The most recent 120 samples (~4 seconds) are ignored so your pre-trigger altitude won't effect the ground baseline.

For almost all uses we suggest keeping this on the 25 Meter (~82 feet) default settings. If you want to test your altimeter by throwing it in the air, or are planning a very low flight you may want to lower the setting.

30 meters

Ratio échantillonnage

The altimeter runs at 50Hz however you can record every sample or every X samples in order to extend the log time. For example if you set the ratio to 1 it will save 1:1 samples, or if you set it to 3 it will save 1 in 3 samples.

1:1 (50Hz)

Max. échantillons

This is the maximum samples the altimeter will log per flight. When it reaches this amount it will stop and save the recording.

Arrêt enregistrement

This setting is how the altimeter decides to stop recording. You can choose either 450 (~9s) or 900 (~18s) samples stable or it will record until the max samples limit unless you press the BUTTON in Manual stop mode.

The samples stable method waits for the devices altitude not to change for the set number of samples. This is defined by not changing by more than +/- 1.0 meters for 98% of the samples, it's a reliable method to stop the recording after landing within 8-10 seconds (300 sample) or 16-20 seconds (600 sample).

Auto: 450 samples stable (~9s)

Suréchantillonnage

Oversampling is a internal setting of the BMP 390 pressure sensor. It is how many samples are taken for each reading. By taking multiple samples for each pressure reading the altimeter reduces noise and increases the resolution of the output.

The sensor can run at 50 samples per second in 4X mode, so we suggest leaving it in this mode as it will offer the highest accuracy.

16x Oversampling

Filtre IIR

The IIR filter is another internal sensor for the BMP390 pressure sensor. It is a Infinite impulse response filter used to enhance pressure measurement accuracy by reducing noise. It's primarily for smoothing out rapid pressure changes.

We suggest not setting this too high as it will cause delay to changes in altitude if set very high.

COEFF 7

Filtre pression

This filter is a software Kalman filter that runs on the altimeters processor.

The Kalman filter uses a prediction step based on a system model and then a correction step using new measurements to refine its estimate, it creates accurate most certain results from data with noise in it.

TruePath 1.0

Sample speed

The sample rate of the altimeter's sensors. 50Hz takes 50 samples per second, 100Hz takes 100 samples per second for higher resolution data.

200 Hz

Hybrid mode

When enabled, the altimeter records at full speed during ascent then switches to half speed after apogee to extend recording time during descent.

Enabled

Synchro capteurs

The filters on the pressure sensor can cause it to lag very slightly behind the Accelerometer and Gyroscope data. The Sync sensors option detects how far out of sync these sensors are. It then corrects the Acceleration and Gyroscope readings to match the pressure sensor.

ACTIVÉ (35 samples / 200ms)

Orientation

This is the orientation you intend to install the Altimeter in your rocket. It's needed to ensure completly accurate angles and orientation charts and reports. Check out the Manual for more information on this.

Down (text up)

Filtre IMU

The IMU filter, or fusion filter takes the data from each axis of the Gyroscope and Accelerometer to calculate the Pitch, Roll, Yaw and tilt angle from vertical. These filters can build up some discrepency over time so it's important to calibrate your sensors to minimise this.

Madgwick 6-Axis

ALP lancement

This is prevention against accidental launch detection.

With this disabled the launch is based only on pressure and something that creates a low pressure can trigger the flight by accident. For example pulling your nose cone off can even trigger it.

With this enabled the rocket also needs to have seen 8 samples (0.25 seconds) of acceleration above this setting in the last 3 seconds as well as the pressure drop to trigger. There is a backup trigger of 1.05 seconds of altitude being above the launch detect setting too.

There are very few situations where this option would cause issues, so we suggest leaving it on.

1.5G

Verrouillage lancement

When enabled, the altimeter locks out recording for a set period after power on to prevent false triggering during setup.

DISABLED

Température statique

A fixed temperature value used for altitude calculation when the external temperature sensor is disabled or not connected.

Hi, It's interesting about the battery. I'm wondering if the unit had in fact gone in to deep sleep. In this state you would need to turn the power switch off before connecting it to USB or it would remain in deep sleep.

It does this depending on the post flight setting and/or reaching maximum safe LiPo temperature (60C).

Best practice is ensuring power switch is off before connecting USB or turning it back on for another flight to be sure. Do let me know if you see that issue again though please as it's of interest to me.
