```
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 PredefinedObservationType[] 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 (PredefinedObservationType c : PredefinedObservationType.values()) System.out.println(c);
    Returns:
    
    an array containing the constants of this enum type, in the order they are declared
  - valueOf
```
public static PredefinedObservationType 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
  - getName
```
public String getName()
```
    Get the name of the observation type.
    
    Specified by:
    
    getName in interface ObservationType
    
    Returns:
    
    name of the observation type
  - getMeasurementType
```
public MeasurementType getMeasurementType()
```
    Get the measurement type.
    
    Specified by:
    
    getMeasurementType in interface ObservationType
    
    Returns:
    
    measurement type
  - getSignalCode
```
public SignalCode getSignalCode()
```
    Get the signal code.
    
    Specified by:
    
    getSignalCode in interface ObservationType
    
    Returns:
    
    signal code
  - getSignal
```
public GnssSignal getSignal(SatelliteSystem system)
```
    Get the signal for a specified satellite system.
    
    Specified by:
    
    getSignal in interface ObservationType
    
    Parameters:
    
    system - satellite system
    
    Returns:
    
    signal for the satellite system, or null if satellite system not compatible
