PNAVACCURACY

This structure indicates valid and invalid PNACCURACY elements.

Syntax

typedef struct tagPNAVACCURACY{
DWORD dwStructureSize;
DWORD dwAv1;
DWORD dwPNReserved;
} PNAVACCURACY;

Members

dwStructureSize

Specifies the size, in bytes, of the PNACACCURACY structure.

dwAv1

Specifies bit flags, one for each member in the corresponding PNACCURACY structure, that indicate whether an element is available. The bit flags defined for the PNAVACCURACY structure are described in the following table.

Flag	Bit	Description
PN_AAC_AHORIZERROR	0	Unsupported
PN_AAC_AVERTICALERROR	1	Unsupported
PN_AAC_EDOP	2	East component of the geometric dilution of precision (EDOP) is valid or invalid.
PN_AAC_NDOP	3	North component of the geometric dilution of precision (NDOP) is valid or invalid.
PN_AAC_VDOP	4	Vertical component of the geometric dilution of precision (VDOP) is valid or invalid.
PN_AAC_PDOP	5	Position component of the geometric dilution of precision (PDOP) is valid or invalid.
PN_AAC_TDOP	6	Time component of the geometric dilution of precision (TDOP) is valid or invalid.
PN_AAC_GDOP	7	Geometric dilution of precision (GDOP) is valid or invalid.
