ASSALAM O ALAIKUM,

anybody has any information regarding Anschütz (STD 20) course bus like baud rate , data format i.e how heading information presented in it. what i so far understand is this is a type of data transmission of gyro heading/course. i have read its name along with NMEA 0183.

i need this information badly because i a device which is transmitting heading data in this format instead of NMEA and i can't understand it.

is it represented like following (this example is from a Doppler device data format which i decode) or any other format.

Byte 1 S M 12 11 10 9
Byte 2 8 7 6 5 4 3 2 1


S --> SIGN , M = Measurement of gyro , compass , speed
M=000 GYRO M=001 MAGNET COMPASS
bit 1------------------12
0.01 m/s--------------(2^12 * 0.01 )=10.24 m/s

PLEASE HELP. i would be very thankful
