摘要

雪水当量(SWE)是水文应用的一个关键参数。在本文中，我们描述了一种新的积雪监测站，它仅通过GPS和伽利略卫星的差分载波相位测量来确定SWE。将SWE估计与几种传统传感器进行比较，以证明可实现的性能。测量结果还表明，仅4颗伽利略卫星就可将RTK定位的总固定时间缩短3分钟。

Estimation of Snow Parameters with GPS and Galileo

The Snow Water Equivalent (SWE) is a key parameter for hydrological applications. In this paper, we describe a novel snow monitoring station that determines SWE solely from differential carrier phase measurements of both GPS and Galileo satellites. The SWE estimates are compared with several traditional sensors to demonstrate the achievable performance. The measurement results also show that just 4 Galileo satellites reduce the combined fixing time of RTK positioning by up to 3 minutes.
