GnssMeasurementsData - Qualcomm Dragonwing Documentation

Specifies the SV pseudo range and carrier phase measurement from a standard positioning engine (SPE). Determine the validity of a field in GnssMeasurementsClock by checking whether its corresponding bit in GnssMeasurementsClock::flags is set.

Field	Type	Description
`flags`	GnssMeasurementsDataFlagsMask	Specifies the valid fields in `GnssMeasurementsData.`
`svId`	`INT16`	Specifies SV ID number. For the SV ID range of each supported constellation, refer to documentation in `GnssSv::svId`.
`svType`	GnssSvType	SV constellation type.
`timeOffsetNs`	`DOUBLE`	Time offset when the measurement was taken, in nanoseconds.
`stateMask`	GnssMeasurementsStateMask	Specifies the GNSS measurement state.
`receivedSvTimeNs`	`INT64`	Received GNSS time of the week in nanoseconds when the measurement was taken. For subnanoseconds part of the time, refer to field of `GnssMeasurementsData:: receivedSvTimeSubNs`. Total time is: `receivedSvTimeNs + receivedSvTimeSubNs`.
`receivedSvTimeSubNs`	`FLOAT`	The subnanoseconds portion of the received GNSS time of the week when the measurement was taken. For a nanoseconds portion of the time, refer to field of `GnssMeasurementsData:: receivedSvTimeSubNs`. Total time is: `receivedSvTimeNs + receivedSvTimeSubNs`.
`receivedSvTimeUncertaintyNs`	`INT64`	Satellite time. All SV times in the current measurement block are already propagated to a common reference time epoch, in nanoseconds.
`carrierToNoiseDbHz`	`DOUBLE`	Signal strength, carrier to noise ratio, in dB Hz.
`pseudorangeRateMps`	`DOUBLE`	Uncorrected pseudorange rate, in meters/second.
`pseudorangeRateUncertaintyMps`	`DOUBLE`	Uncorrected pseudorange rate uncertainty, in meters/sec.
`adrStateMask`	GnssMeasurementsAdrStateMask	Bitwise OR of `GnssMeasurementsAdrStateMask`.
`adrMeters`	`DOUBLE`	Accumulated delta range, in meters.
`adrUncertaintyMeters`	`DOUBLE`	Accumulated delta range uncertainty, in meters.
`carrierFrequencyHz`	`FLOAT`	Carrier frequency of the tracked signal, in Hz.
`carrierCycles`	`INT64`	The number of full carrier cycles between the receiver and the satellite.
`carrierPhase`	`DOUBLE`	The RF carrier phase that the receiver has detected.
`carrierPhaseUncertainty`	`DOUBLE`	The RF carrier phase uncertainty.
`multipathIndicator`	GnssMeasurements MultipathIndicator	The multipath indicator could be unknown, present, or not present.
`signalToNoiseRatioDb`	`DOUBLE`	Signal to noise ratio, in dB.
`agcLevelDb`	`DOUBLE`	Automatic gain control level, in dB.
`basebandCarrierToNoiseDbHz`	`DOUBLE`	Baseband signal strength, in dB Hz. This field should always be available in the measurement report.
`gnssSignalType`	GnssSignalTypeMask	GNSS signal type mask of the SV. This field should always be available in the measurement report.
`fullInterSignalBiasNs`	`DOUBLE`	The full intersignal bias (ISB) in nanoseconds. This value is the sum of the estimated receiver-side and the space-segment-side intersystem bias, interfrequency bias, and intercode bias.
`fullInterSignalBiasUncertaintyNs`	`DOUBLE`	1-sigma uncertainty associated with the full intersignal bias in nanoseconds.
`cycleSlipCount`	`UINT8`	Increments when a cycle slip is detected.
