My team and I have just fired a CanSat and are a bit confused about the data we got from our magnetometer(Mag_data.png). We would assume that it should be constant.

We used the 9 Degrees of Freedom sensor: https://www.sparkfun.com/products/12636

From the sensor we got 3 values, x, y, and z. We used these equations to calculate the raw data to Gauss.

Magnetic Flux Density = sqrt(MagX^{2} + MagY^{2} + MagZ^{2})

Here are some raw sample data:

MagX MagY MagZ

1,100192267 0,993682669 -0,37018952

1,082125309 0,993133335 -0,372142705

1,066866054 0,994903409 -0,371532334

1,047517319 0,995818964 -0,373912778

Could this be caused by noise from the other components, or are we missing something crucial
