用MATLAB在产生的观测数据中捕获其中PRN 号码为“5”C/A 码。 （1） 观测数据应该有一定的多普勒频偏D f（-10kHz〈D f〈+10kHz）； （2） 加入高斯白噪声，使其信噪比为-20dB； （3） 捕获成功后，应给出捕获标志，并给出估计的频偏和码偏值。(Generated by MATLAB in which observed data capture PRN number is " 5" C/A code. (1) there should be some observations of Doppler shift D f (-10kHz < D f < +10 kHz) (2) by adding Gaussian white noise, so SNR is-20dB (3) capture success After the capture flag to be given, and given the estimated frequency offset and code bias values.)

The modeling and attitude stabilization control problems of a four-rotor vertical takeoff and landing unmanned air vehicle (UAV) known as the quadrotor are investigated.The quadrotor’s attitude is represented by the unit quaternion rather than Euler angles to avoid singularity problem. Taking dynamical behavior of motors into consideration and ignoring aerodynamic effect, a nonlinear controller is developed to stabilize the attitude.The control design is accomplished by using backstepping control technique.The proposed control law is based on the compensation for the Coriolis and gyroscope torques. Applying Lyapunov stability analysis proves that the closed-loop attitude system is asymptotic stable. Moreover, the controller can guarantee that all the states of the system are uniformly ultimately bounded in the presence of external disturbance torque.The effectiveness of the proposed control approach is analytically authenticated and also validated via simulation study.
