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

i

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

i

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.

25 meters

Ratio échantillonnage

i

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:

Max. échantillons

i

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

12000

Arrêt enregistrement

i

This setting is how the altimeter decides to stop recording. You can choose either 300 or 600 samples stable or it will record until it's 10000 sample 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: 300 samples stable

Suréchantillonnage

i

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

i

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

i

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.

Kalman 2 (default)

Changement verrouillage

i

This is how we detect a lockout. If the pressure changes by this much in a single sample downwards (pressure increase, lower altitude) then it's likely to be a false reading. Multiply the setting by 32 to get the speed in meters per second that it will trigger at.

0.5 meters

Synchro capteurs

i

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 (21 samples / 220.00ms)

Orientation

i

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.

Upwards (text up)

Filtre IMU

i

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

i

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.

1.4G

Verrouillage lancement

i

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

DISABLED

Température statique

i

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

15.00 °C

Capteur temp.

i

If an external MT1 temperature sensor is connected, this controls whether it is used for logging only or also for altitude calculations.

Sortie 1 activée

i

Disable or enable the output from being able to turn on or off.

DÉSACTIVÉ

Sortie 1 déclencheur

i

After apogee (altitude)

This method triggers when the altitude drops below the set altitude after apogee is detected.

After apogee (time)

This method triggers the defined seconds after apogee is detected.

After launch (altitude)

This method is activated if/once the altimeter exceeds the set altitude after launch.

After launch (time)

This option triggers the defined seconds after launch is detected.

After burnout (time)

This method triggers the defined seconds after burnout is detected.

After apogee (altitude)

Sortie 1 durée

i

This is how long the output should trigger ON state when the rules are met.

2000ms

Sortie 1 altitude

i

This is the altitude to trigger at if using a trigger method that works on altitude.

For example if you set this to 75m and After apogee (altitude) for the trigger then the output will turn on at 75m on descent above the launch altitude.

0 meters

Sortie 1 temps

i

This is the time variable for output triggers that work on time.

For example if you set this to 3 seconds and After apogee (time) as the trigger then the output will turn on 3 seconds after apogee.

0 seconds

Verrouillage altitude

i

Altitude lock is a safety feature that prevents the output from triggering if the altitude is below this level when the rules are met.

50.00 m

Verrouillage inclinaison

i

This is another safety feature. It can be used to disable the output if the rocket has gone too far from vertical.

For example if you set the tilt angle lock to 40 degrees then the output will not fire if the rocket is more than 40 degrees from vertical. To disable set this to 0.

Prédiction et aérofreins

Ceci est un aperçu des paramètres utilisés pour ce vol.

Le Mercury peut prédire l’apogée pendant la phase de vol libre. Ces paramètres contrôlent le calcul et le système d’aérofrein.

Masse sèche

i

The total mass of the rocket after motor burnout (dry mass). This is used for the ballistic prediction of apogee altitude. Enter the mass without the motor propellant, or the mass at burnout.

0.1500 kg

Coefficient Cx

i

The aerodynamic drag coefficient (Cd) of the rocket. This is used with the rocket area to calculate aerodynamic drag during coast. A typical model rocket has a Cd of 0.4 to 0.8. You can find this value from OpenRocket or RockSim simulations.

0.750

Surface référence

i

The cross-sectional reference area of the rocket in square meters. This is typically the area of a circle with the body tube diameter. For example a 38mm tube has an area of approximately 0.00113 m².

0.00100 m²

Gas constant

i

The specific gas constant for dry air, used in the atmospheric model for altitude and density calculations. The standard value is 287.05 J/(kg·K). You shouldn't need to change this unless you know what you're doing.

287.05 J/(kg·K)

Les paramètres suivants configurent le système d’aérofrein.

Aérofrein activé

i

Enables or disables the active air braking system. When enabled, the Mercury will deploy air brakes via the configured servo channel to try and reach the target altitude. Firmware 2.1+ required.

OFF (default)

Servo channel

i

Which servo output channel the air brake mechanism is connected to. GP6 and GP7 are the two onboard servo headers, I2C channels are for an external servo expander board.

GP6

Deploy speed

i

The speed at which the air brakes deploy. The Mercury gradually increases the servo angle until the predicted apogee matches the target rather than going full on/off. This setting controls how quickly it ramps up to full braking.

Medium (default)

Altitude cible

i

The target apogee altitude in meters. The air brake system will try to slow the rocket so it reaches this altitude.

300.00 m

Over shoot %

i

The percentage over the target altitude to aim for until within 15% of the target. This helps prevent undershooting if the prediction is slightly off early in the coast. For example, with a 1000m target and 5% early adjustment, the Mercury will aim for 1050m until it passes 850m.

5.00%

Activation altitude

i

The air brake system activates after burnout, but won't engage until the rocket has reached this percentage of the target altitude. This prevents the brakes from deploying too early when predictions may be less accurate.
