针对对流层湿延迟参数估计及水平梯度处理策略对精密单点定位影响的问题, 以9个多系统实验网实测数据为基础, 设计了6种对流层延迟处理方案并进行实验. 实验结果表明, 观测时长在8 h时段内, BDS/GPS定位模式下, 对流层延迟的水平梯度处理不宜采用随机游走模型; 采用随机游走估算对流层湿延迟参数, 且不估算或使用分段常数处理水平梯度的策略相对占优. 动静态精密单点定位结果显示, BDS/GPS采用分段常数或随机游走进行对流层湿延迟参数估算和分段常数处理水平梯度的策略相对占优, 采用随机游走处理水平梯度的策略稍弱. 总体而言, BDS较GPS估算的对流层延迟及定位精度稍弱; 海洋周边6种方案解算结果差异较内陆站大. 静态精密单点定位模式下, 随着观测时长的增加, 6种方案定位误差趋势趋于一致, 误差大小基本在2 cm内, 观测时长大于12 h时, 随机游走估算对流层湿延迟参数和不考虑水平梯度的处理策略整体较优.
