In this paper,a method for real-time rocket attitude determination by measuring the difference in GPS carrier phases is proposed. First,a single-difference model is established for the attitude determi-nation based on the relevant measurement principle,and a real-time attitude solution for the projectile with multiple GPS antennas is provided. Then,baseline vectors are estimated with the least-square meth-od. Finally,the recursive algorithm is adopted to simulate the GPS attitude measurements. Results show that the algorithm preferably estimates the attitude of rocket projectiles,which successfully validates the presented approach.
