    Hi. 
    
 
    As i detected in Adxrs623's  datasheet, Null voltage has around +_100mv Voltage instability.
    
 
    The problem is the Scale factor is around 12.5mV. So the Null voltage instability is a huge problem for me(100mv means 100mv/12.5mvperdeg/sec=8deg/sec)
    
 
    what is your suggestion for solve this problem?
    
 
    thanks.

        Hi
        
 
        Thanks again and again for your replays 
        
 
        As i told you i'm using this gyro for My masters thesis and for quad application.
        
 
        As you mentioned, and i detected recently, calibration may be is the solution. Now i'm looking for leads for calibration methods and i will be grateful if you lead.
        
 
        And about the accuracy, because of academic peruses, it should be as much as possible.
        
 
        thanks again
