【摘要】 卫星授时在电力电子技术等诸多领域起着至关重要的作用，但是目前大批量应用的单频接收机没有开发授时功能或者精度较低。针对上述需求，本文提出了一种适用于单频接收机的高精度时间生成方法。实施方法中，通过BDS-3和GPS双系统组合的方式增加有效观测卫星的数量；在Hatch滤波的基础上引入载波相位信息，对伪距观测值进行重构；借助卫星共视法原理，采用站间单差算法对输出时间进行标校，把单频接收机校正到基准站的高精度时间频率水平上。经实验验证，经标校后其1PPS输出精度可达纳秒级，系统方差在千秒级时段内稳定在1 ns左右。更多还原

【Abstract】 Satellite timing is crucial in various fields, including power electronics technology. However, the single-frequency receivers in current widespread use either lack timing functions or have low accuracy. To address these needs, this paper proposes a high-precision time generation method suitable for single-frequency receivers. This method increases the number of effective observation satellites by combining the BDS-3 and GPS dual systems. Carrier phase information is introduced based on Hatch filtering to reconstruct the pseudorange observation values. Utilizing the satellite common view method principle, the inter-station single difference algorithm calibrates the output time, aligning the single-frequency receiver with the high-precision time and frequency standards of the reference station. Experimental verification shows that the accuracy of the 1PPS output can reach nanoseconds after calibration, with system variance remaining stable at approximately 1 ns over a kilosecond period.更多还原
