Constructor & Destructor Documentation

TPositionGpsMeasurementData()

IMPORT_C

TPositionGpsMeasurementData

(

)

Default constructor for a TPositionGpsMeasurementData .

Member Functions Documentation

CarrierNoiseRatio()

IMPORT_C TInt

CarrierNoiseRatio

(

)

const

Returns the carrier to noise ratio from the satellite measurement. SetCarrierNoiseRatio

Doppler()

IMPORT_C TInt

Doppler

(

)

const

Returns the Doppler from the satellite measurement. Result should be multiplied by 0.2 to obtain actual frequency For more information see: 3GPP TS25.331. SetDoppler

FractionalGpsChips()

IMPORT_C TInt

FractionalGpsChips

(

)

const

Returns the fractional value of the GPS code-phase measurement. Scale factor 2-10. For more information see: 3GPP TS25.331. SetFractionalGpsChips WholeGpsChips

MultiPathIndicator()

IMPORT_C TMultiPathIndicator

MultiPathIndicator

(

)

const

Returns the MultipathIndicator from the satellite measurement. This is an enumeration indicating the level of multi path error. For more information see: 3GPP TS25.331. SetMultiPathIndicator TMultiPathIndicator

PseudoRangeRmsError()

IMPORT_C TUint

PseudoRangeRmsError

(

)

const

Returns a bitmap indicating the pseudo range RMS Error from the satellite measurement. For more information see: 3GPP TS25.331. SetPseudoRangeRmsError

SatelliteId()

IMPORT_C TInt

SatelliteId

(

)

const

The ID of the satellite measured. SetSatelliteId

SetCarrierNoiseRatio(TInt)

IMPORT_C void

SetCarrierNoiseRatio

(

TInt

aCarrierNoiseRatio

)

Sets the carrier noise ratio for the satellite signal. For more information see: 3GPP TS25.331. CarrierNoiseRatio

Parameters

TInt aCarrierNoiseRatio

The carrier noise ratio to be assigned

SetDoppler(TInt)

IMPORT_C void

SetDoppler

(

TInt

aDoppler

)

Sets the Doppler from the satellite measurement. Value should be actual value divided by 0.2. For more information see: 3GPP TS25.331. SetDoppler

Parameters

TInt aDoppler

Actual doppler frequency divided by 0.2

SetFractionalGpsChips(TInt)

IMPORT_C void

SetFractionalGpsChips

(
