The fields are:

  • 1 - Sentence version [1]
  • 2 - Message name
  • 3 - PRN set by the req_ftest element; (Field always present) Can be "CW" for continuous wave testing.
  • 4 - Last observed estimation of the signal strength referenced to the antenna port with assumption of end to end noise figure configured through the RfType attribute; (Field is empty if the signal is not detected or lost) In the case of CW, this is the best signal strength seen.
  • 5 - Average estimation of the signal strength referenced to the antenna port over x seconds period, where x is a "avg_int_sec" attribute of the req_ftest configuration element ; (Reports empty field before acquisition of GPS signal, and x-1 samples between repeated reports after acquisition)
  • 6 - Units of two fields above [dBm]
  • 7 - Last observed estimation of the C/No referenced to the antenna port with assumption of end to end noise figure configured through the RfType attribute; (Field is empty if the signal is not detected or lost)
  • 8 - Average estimation of the C/No referenced to the antenna port over x seconds period, where x is a "avg_int_sec" attribute of the req_ftest configuration element; (Reports empty field before acquisition of GPS signal, and x-1 samples between repeated reports after acquisition)
  • 9 - Last observed estimation of the C/No seen at the baseband processor; (Field is empty if the signal is not detected or lost)
  • A - Average estimation of the C/No [dB Hz] over x seconds period seen at the baseband processor, where x is a "avg_int_sec" attribute of the req_ftest configuration element; (Reports empty field before acquisition of GPS signal, and x-1 samples between repeated reports after acquisition)
  • B - Units of two fields above [dB Hz]
  • C - Last seen ref clock offset [ppb]
  • D - Uncertainty of the value above [ppb]
  • E - RTC clock offset [ppm]
  • F - CNTIN measurement status
    • NU - Not used
    • OK - OK
    • NI - No input frequency was detected on CNTIN pin
    • UD - Platform HAL failed to call RefFreqStatus() on GlEngineOnFreqUpdate callback request
    • UC - Platform HAL reported reference frequency as unreliable during the CNTIN interval
  • G - TCXO offset as measured by CNTIN [ppb] ( Field is empty if CNTIN is failed or not configured)
  • H - Number of successfully decoded words
  • I - Total number of decoding attempts
  • J - Word Error Rate [percent]
  • K - RF AGC value (combined value with the analog AGC + digital AGC)
  • L - Energy Drop-Out Counter.
  • M - RF Analog AGC value
  • CC - checksum

The carrier-wave PGLOR,FTS output is slightly different:

 $PGLOR,1,FTS,CW,-124.8,-dBm,126886,0.7,ppb*30
        1  2  3   4      5     6     7   8

The fields are:

  • 1 - Sentence version [1]
  • 2 - Message name
  • 3 - "CW" for continuous wave testing.
  • 4 - Best CW signal strength seen.
  • 5 - Units of CW signal strength [dBm]
  • 6 - Frequency offset of CW signal (200KHz should be 126950.27 ppb)
  • 7 - Uncertainty of frequency offset.
  • 8 - Units of two fields above [ppb]
  • CC - checksum
