Enumerate for all the Observation Types for Rinex 2 and 3. For Rinex 2, there is an two-character enumerate composed of the Observation Code (C,P,L,D,S) and the Frequency code (1,2,5,6,7,8). For Rinex 3 there is a three-character enumerate composed of the Observation Code (C,L,D,S), the frequency code (1,2,5,6,7,8) and a final attribute depending on the tracking mode or channel.

- Method Detail
  - values
```
public static ObservationType[] values()
```
    Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
    for (ObservationType c : ObservationType.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static ObservationType valueOf(String name)
```
    Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
    
    Parameters:
    
    name - the name of the enum constant to be returned.
    
    Returns:
    
    the enum constant with the specified name
    
    Throws:
    
    IllegalArgumentException - if this enum type has no constant with the specified name
    
    NullPointerException - if the argument is null
  - getMeasurementType
```
public MeasurementType getMeasurementType()
```
    Get the measurement type.
    
    Returns:
    
    measurement type
  - getSignalCode
