Field Description
fff.f Frequency in kHz (283.5 to 325)
x Tune mode (M = manual tune mode, A = automatic tune mode)
ddd MSK bit rate (100, or 200 bps)
y MSK rate selection (M = manual tune mode, A = automatic tune mode)
n Period of output of performance status message, 0 to 100 seconds ($CRMSS)
An example of this message follows:
$CRMSK,287.0,A,100,A,0*4A
7.8.2 Performance Status Query ($GPCRQ)
This standard NMEA query prompts the SBX receiver for its performance
status:
$GPCRQ,MSS<CR><LF>
The internal SBX will reply with the following response:
$CRMSS,xx,yy,fff.f,ddd*CS
Field Description
xx Signal Strength (dB µV/m)
yy Signal to Noise Ratio (dB)
fff.f Frequency in kHz (283.5 to 325)
