Selection/Projection
If you for example only need GPS Positions are needed, you only need to extract latitude and longitude informations can be extracted from the sentences. As you can see in In "Supported Sentences" table can be seen, that the sentences GGA, GLL and RMC do have the needed information you want to have. To extract the this information you want to do a Selection can be done, to get only these sentence types and a Projection, to extract only the needed informations.
