MOI values of spacecraft are critical values to influence the control accuracy and attitude in the orbit. Traditionally, MOI values are measured by air floating MOI measurement equipment, but the air resistance may influence the accuracy of MOI measurement. How to evaluate the scale of the influence and to reduce the influence will reduce measurement error. The thesis designs a kind of simulation boards to research the air resistance influence, then using the air influence factors to calculate the influence in quantity, and finally using the method to compensate the air resistance influence. The influence of air resistance can be compensated by calculating the coefficient of air resistance, and compensation will eliminate 96% of the error.
