ABSTRACT:
An apparatus and method for modeling dynamic effects on a gyroscope. The dynamic effects are represented by a dynamic effects function. The gyroscope is placed in an oven. A test controller, coupled to the oven, controls the oven to modify the temperature of the gyroscope according to a predetermined temperature function, measures an actual temperature value of the test oven and a gyroscope drift value at predetermined time intervals during the predetermined temperature function, and calculates coefficients of the dynamic effects function as a function of the actual temperature and gyroscope drift values at the predetermined time intervals.
