Members

dwStructureSize

Specifies the size, in bytes, of the PNINDSTATION structure

tiTime

Unsupported

ssState

State of this station

dwStationIDNum

Specifies the pseudo-random noise (PRN) signal number, space vehicle identification (SVID) satellite number, or unique station number

fUsed

Boolean that specifies if the station is used for calculations. TRUE indicates that the station is used. FALSE indicates that the station is not used.

dSatElevation

Specfies the satellite elevation, measured in radians. Satellite elevation must be from 0 through pi/2.

dSatAzimuth

Specifies the satellite azimuth, measured in radians. Satellite azimuth must be from 0 through 2 pi.

dSignalStrength

Specifies the signal strength, in decibels

dwCoverage

Unsupported

siAvIndStation

Indicates valid and invalid PNINDSTATION elements

dwPNReserved

Reserved for future use

Remarks

For Global Positioning System (GPS) receivers, dwStationID is defined as the pseudo-random noise (PRN) signal number or space vehicle identification (SVID) satellite number. Numbers from 33 through 64 are reserved for the Wide Area Augmentation System (WAAS). Numbers from 65 through 96 are reserved for the Global Navigation Satellite System (GLONASS).
