To real time monitor the Rolling Rate and Phase of high spin projectile in flighting,general measurement method is difficult to meet the engineering requirements,this paper presents a geomagnetic sensor based phaselocked loop tracking loop measurement method. The rolling measurement model of PLL with different order is established by SIMULINK, determine the appropriate loop filter order and integraldump time, complete the realtime measurement of the rolling rate and phase. Simulation results show, 2nd order phase PLL in highspin roll measurement, there is a large tracking error and tracking more slowly in phase tracking; 3rd and 4th order phase PLL can tracking effectively to carry the frequency and phase of geomagnetic sensor signal, thereby calculating the high spin rolling speed and phase, it has a higher application value.
