#PC USB GPS RECEIVER HOW TO#
Full details of how to do this are in the ComDebug program Help and on our Parsing page.Īnother Example of a GPS Data String $GPRMC,hhmmss,A,llll.ll,N,yyyyy.yy,W,kk.k,tt.t,ddmmyy,mm.m,W*CSĪ is the status: data valid (A) or receiver warning (V) For the longitude channel you might search for 'N,' and extract until ','. In this example, for the latitude channel, you might tell Windmill to search for 'GLL,' and extract up to the next comma. Windmill will collect this information as 2 "channels" of data, but you have to tell it how to recognise the desired information. Out of this data string you might want to record just the latitude and longitude. This might look something like thisįirst, there is a NMEA code ($GPGLL), then the latitude, North or South, Longitude, East or West, Time (hhmmss), Data Valid (A), Carriage Return and Line Feed. The GPS receiver sends data in a string or sentence.
