利用GPS水准法和同步改正法实现了跨海高程基准的传递。GPS传递结果与同步改正法传递结果相差3cm。结果表明，GPS结合大地水准面精化技术实现跨海高程基准传递省时省力、方便可靠。%Height datum transference across the sea was realized by using the method of GPS height datum transference and synchronous reduction. The results got by the method of GPS height datum transference and synchronous reduction vary in height by 3cm. The result showed that to realize height datum transference across the sea using the method of GPS combined with geoid refining technology is more time-saving, con- venient and reliable.
