I am currently using the ADIS16405 and ADIS16448 inertial sensor for our small satellite application. During the cold stage(dwell at -35degC) of our thermal cycle test , the temperature reading of the inertial sensor is around -42degC which is lower than the expected temperature. Thus, I am wondering
1) What is the output noise and the accuracy of the inertial sensor temperature measurement?
2) Does the accuracy of the temperature measurement drops when the surrounding temperature goes below certain negavite temperature? I understand from the data sheet that the sensor operating temperature range is between -40 to 85 degC for ADIS16448 and -40 to 105 degC for ADIS16405
