Way to calibrate only airspeed sensor..?

[Truth_T]

Hello.

1. Suggestion :

now “preflight_calibration” in mission planner does both gyro calibration and air speed calibration. I want to seperate the gyro calibration and air speed calibration

2. Reason :

Airspeed sensor calibration problem

Hi, I am using a Matek airspeed sensor ASPD-7002. When I recalibrate it in a few minutes after turning power on, I get pretty good readings in still air, close to zero (0-3km/h, sometimes 4-5). But I usually don’t have a computer in the field. Soon after normal switching on and calibration, the speed readings are about 13-15 km/h in still air. Turning the power off and on doesn’t help. I tried to warm up the electronics for ten minutes, disconnect the battery and connect it back, airspeed dr…

in the above link, you can confirm that airspeed sensor should be calibrated manually before every flight.

so, we have to press “pre-flight calibration” button before every flight.

the problem is, “pre-flight calibration” button also calibrates gyro and acc.

I will operate VTOL on moving ship, in the deep ocean(south pacific). because there is no place that calibrate gyro and acc, I have to turn off automatic calibration.

but airspeed sensor calibration forces me to do gyro and acc calibration on shaking fishing vessels.

I have programming knowledge but I hope I don’t need to write lua script or other plugins…

Gyros are only calibrated at preflight when using a copter. With plane, only the airspeed sensor is calibrated…

 if (CMB_action.Text == actions.Preflight_Calibration.ToString())
                {
                    if (MainV2.comPort.MAV.cs.firmware == Firmwares.ArduCopter2)
                        param1 = 1; // gyro
                    param3 = 1; // baro / airspeed
                }
