摘要
利用ＣＲＳ３．０海潮模型计算了海潮对我国沿海地区ＧＰＳ测站的影响。结果表明海潮对我国ＧＰＳ测站的影响由东至西逐渐减小，垂直方向的影响远远大于水平方向，对东南部沿海的影响一般可达厘米量级。海潮改正对ＧＰＳ基线解算的实例表明，这一影响不仅反映在基线向量上，而且也反映在基线分量上。
The effect of ocean loading tieds on Chinese coastal GPS stations is calculated by using CRS3.0 ocean loading tiedes model.The results show that the effect of ocean loading tides on GPS is gradually reduced from east to west in China, and that the effect of vertical component is much greater than horizontal. The effect on south-east coast area of China may reach a cm magnitude normally.The case of ocean loading tides correction of GPS baseline calculation showes that the effect of ocean loading tides of GPS baseline calculation not only reflects on baseline vector but also on baseline component.
