This structure defines specific data elements associated with carrier wave test results returned from the driver.
SizeStructure size.
VersionVersion number.
TestResultStatusNTSTATUS value indicating whether this fix contains a valid data, or if the GNSS engine or driver encountered any errors in getting the measurements for the carrier wave test.
Success - carrier wave test successfully started.
Failed - with error code: test not implemented, carrier wave test already in progress, fix session in progress, or other failure.
SignalToNoiseRatioSignal to noise ratio in the carrier wave in dB-Hz.
FrequencyFrequency of the carrier wave detected in the measurement band.
This frequency is provided as a difference to GPS frequency (1575.42 MHz) in kHz.
UnusedPadding buffer reserved for future use.
