GPS_VALID_ (Windows Embedded CE 6.0)
1/6/2010
This family of constants specifies which of the fields in the GPS_POSITION structure are valid.
The GPSGetPosition function fills a GPS_POSITION structure with information that includes the latitude and longitude returned by GPS hardware. GPS_POSITION includes a field named dwValidFields, which specifies the fields in the structure that are valid, using a bitwise combination of the constants in the following table.

|---|---|
GPS_VALID_UTC_TIME = 0x00000001 |
If set, the stUTCTime field is valid. |
GPS_VALID_LATITUDE = 0x00000002 |
If set, the dblLatitude field is valid. |
GPS_VALID_LONGITUDE = 0x00000004 |
If set, the dblLongitude field is valid. |
GPS_VALID_SPEED = 0x00000008 |
If set, the flSpeed field is valid. |
GPS_VALID_HEADING = 0x00000010 |

GPS_VALID_ALTITUDE_WRT_SEA_LEVEL = 0x00000040 |
If set, the flAltitudeWRTSeaLevel field is valid. |
GPS_VALID_ALTITUDE_WRT_ELLIPSOID = 0x00000080 |
If set, the flAltitudeWRTEllipsoid field is valid. |
GPS_VALID_POSITION_DILUTION_OF_PRECISION = 0x00000100 |
If set, the flPositionDilutionOfPrecision field is valid. |
GPS_VALID_HORIZONTAL_DILUTION_OF_PRECISION = 0x00000200 |
If set, the flHorizontalDilutionOfPrecision field is valid. |
GPS_VALID_VERTICAL_DILUTION_OF_PRECISION = 0x00000400 |
If set, the flVerticalDilutionOfPrecision field is valid. |
GPS_VALID_SATELLITE_COUNT = 0x00000800 |
If set, the dwSatelliteCount field is valid. |
GPS_VALID_SATELLITES_USED_PRNS = 0x00001000 |
If set, the rgdwSatellitesUsedPRNs field is valid. |
GPS_VALID_SATELLITES_IN_VIEW = 0x00002000 |
If set, the dwSatellitesInView field is valid. |
GPS_VALID_SATELLITES_IN_VIEW_PRNS = 0x00004000 |
If set, the rgdwSatellitesInViewPRNs field is valid. |
GPS_VALID_SATELLITES_IN_VIEW_ELEVATION = 0x00008000 |
If set, the rgdwSatellitesInViewElevation field is valid. |
GPS_VALID_SATELLITES_IN_VIEW_AZIMUTH = 0x00010000 |
If set, the rgdwSatellitesInViewAzimuth field is valid. |
GPS_VALID_SATELLITES_IN_VIEW_SIGNAL_TO_NOISE_RATIO = 0x00020000 |
If set, the rgdwSatellitesInViewSignalToNoiseRatio field is valid. |
