鉴于载波相位观测量可提供高精度定位信息的特点,分析了在高动态环境获得载波相位观测量的三种可 能方法,对三种方法的估计精度和动态跟踪能力进行了比较. 提出了一种适合GPS 系统的高动态环境载波相位 测量方案.(View of the carrier phase measurements can provide accurate location information, analyzes the dynamic environment in the high carrier phase measurements to obtain three possible methods, three methods of estimation accuracy and dynamic tracking ability was compared. Presents a GPS system for high dynamic carrier phase measurement program.)

Particle swarm optimization has been used to solve many optimization problems since it was proposed by Kennedy and Eberhart in 1995 [4]. After that, they published one book [9] and several papers on this topic [5][7][13][15], one of which did a study on its performance using four nonlinear functions adopted as a benchmark by many researchers in this area. In PSO, each particle moves in the search space with a velocity according to its own previous best solution and its group’s previous best solution. The dimension of the search space can be any positive integer.

说明：  谐波小波滤波再加上随机减量，谐波小波相当于带通滤波器，效果很好(Coupled random harmonic wavelet filter reduction, harmonic wavelet is equivalent to band-pass filter, the effect is very good)
