【摘要】 为了提高定位精度和达到动态定位的实时性,提出了一种新的GPS定位算法——伪距差法,它消除了天线相位中心偏差、接收机时钟和热噪声误差的影响,减弱了对流层和电离层延迟、卫星星历误差和轨道误差等一些误差干扰,有效提高了定位精度。由于算法简单,解算速度快,易于编程,能满足实时性要求。最后通过实测数据验证了算法的正确性和有效性。更多还原

【Abstract】 In this paper, a novel arithmetic of GPS positioning - pseudo differential that can improve positioning and achiever real - time of dynamic positioning is proposed. Some error such as: the wrap of antenna phasic center, receiver clock error and heat noise is eliminated. It mitigate another error resulting form troposphere and ionosphere delay, satellite calendar and orbit etc. therefore, it is good for improving position precision. Because for its simple, the rapidness of calculate and the facility of program it can satisfy request of real - time. The finally, the correctness and validity of the arithmetic is validated by measurement data.更多还原
