```
public IonosphereBDGIMMessage(SatelliteSystem system,
                              int prn,
                              String navigationMessageType)
```
    Simple constructor.
    
    Parameters:
    
    system - satellite system
    
    prn - satellite number
    
    navigationMessageType - navigation message type
- Method Detail
  - getAlpha
```
public double[] getAlpha()
```
    Get the α coefficients.
    Beware Orekit uses SI units here. In order to retrieve the more traditional TECu, use Unit.TOTAL_ELECTRON_CONTENT_UNIT.fromSI(msg.getAlpha()[i])
    
    Returns:
    
    α coefficients (m⁻²)
    
    See Also:
    
    Unit.TOTAL_ELECTRON_CONTENT_UNIT
  - setAlphaI
```
public void setAlphaI(int i,
                      double alphaI)
```
    Set one α coefficient.
    Beware Orekit uses SI units here. In order to use the more traditional TECu, use msg.setAlpha(i, Unit.TOTAL_ELECTRON_CONTENT_UNIT.toSI(ai))
    
    Parameters:
    
    i - index of the coefficient
    
    alphaI - α coefficient to set (m⁻²)
    
    See Also:
    
    Unit.TOTAL_ELECTRON_CONTENT_UNIT
