    hello people....i am using 3DM GX1 and 6dof v4 ( bluetooth enabled )
    i want to know about this CHR 6D ..... is it reliable ?? i mean how much error do you get for measurements ?
    and what is the output format ??
    do we have to convert the output values using some formula to get the desired values in desired units ?? ( i mean as in 6DOF v4 , it gives adc values which need to be converted )
    please reply asap.....
    thanks

    Using GPS velocity to infer a reference vector (UAV nose) is not ideal though. In side-wind situations for example. Having a Magnetometer allows to have a cleaner reference vector for attitude correction. Biggest drawback is to account for local magnetic field perturbations and cancel them out. Not a simple problem with our electirc UAVs.

    The inclusion of a magnetometer can allow a complete attitude solution without a GPS. Good for inside or other GPS denied environments.

    That usually means a three-axis magnetometer. Not technically accurate to call it 9DoF but everyone does so anyway.,...
