5 Using the AHRS-1 / MAG-1 and SP-X sensor packages
in flight
The pilot in command of the aircraft has to be aware of the following:
The SP-X sensor packages are not certified by the FAA or any other agency for use during IFR (instrument flight
rules). This implies that any such flight that uses the SP-X sensor packages as reference for either heading, turn
and bank or horizon is illegal.
6 RS232 NMEA enabled GPS receiver message
The AHRS-1 has the ability to be connected to a NMEA enabled RS232 GPS receiver to allow the AHRS-1 to use the
actual ground speed in the attitude aiding algorithms.
The NMEA enabled RS232 GPS receiver must be able to output a GPRMC message (The Recommended Minimum
sentence defined by NMEA for GPS/Transit system data.) This message is defined as:
$GPRMC,hhmmss,status,latitude,N,longitude,E,spd,cog,ddmmyy,mv,mvE,mode*cs<CR><LF>
Example: $GPRMC,083559.00,A,4717.11437,N,00833.91522,E,0.004,77.52,091202,,,A*57
