When receiving the GGA sentence, the quality type is checked using the QI (Quality Indicator)
as mentioned in the table above.
- If the quality is valid, the operating state is indicated with the position and time information.
- If the quality is invalid, the next GNS sentence is referred.
- See 5.2 for method to display the quality information on the regular screen.
