摘要: 提出了一种按仰角加权的多通道GPS共视资料处理算法,充分利用了所有观测数据,同时抑制了多径等因素影响,从而可提高共视比对精度。对日本邮政省通讯研究所(CRL)和国家授时中心(NTSC)2002年5月~2003年3月的多通道共视比对的处理结果表明,新的处理算法结果更接近真实钟差。Abstract: A new algorithm with weight in accordance to the elevation is introduced.The algorithm may decrease the influence of multi-path effect,on the other hand,it may utilize the data of all observations.The result of the multichannel GPS observations datum from Communications Research Laboratory(CRL) and National Time Service Center(NTSC) shows that the more accurate time synchronization may be obtained with the new algorithm.
