Default implementation Gnss HAL
Test: On Angler, GPS location available on Maps. All interfaces other
than AGnssRil, AGnssNavigationMessage and GnssNi are functionally tested. AGnssRil and
AGnssNavigationMessage are not implemented by conventional GPS HALs in Google devices that would be
upgrading to O.
