A recent NERC-funded proof of concept award successfully demonstrated that Global Navigation Satellite System (GNSS) signals reflected off the sea surface and received by very low cost (<£30) GPS receivers can be used to estimate the difference in height between the receiver and the water. This represents a method of remotely sensing tidal elevations and, if averaged over time, mean sea level. These could be routinely and remotely measuring sea level at a cost that would allow unprecedented numbers of systems to be deployed around the world by organisations of all sizes and levels of funding.Here we propose to take the initial proof of concept from TRL 3 up to TRL 7 by designing a self-contained unit that receives, records and processes the required signals to output a tidal water level in near real time and at a target hardware and assembly cost of less than £100. The demonstration units will be tested and used by our project partners, the RNLI, initially to provide tidal information at an intertidal causeway with a history of RNLI rescues of members of the public who have become stranded by the rising tide.The technology has the potential to be rolled out not only across the UK but globally, potentially as open source designs & firmware, revolutionising the ability to collect tidal and sea level data at an unprecedented price point and operational simplicity.

最近由NERC资助的概念验证奖成功证明，全球导航卫星系统（GNSS）信号从海面反射并由非常低成本（<30英镑）的GPS接收器接收，可用于估计接收器和水之间的高度差。这是一种遥感潮汐高度的方法，如果按时间平均，还可以遥感平均海平面。这些可以是常规和远程测量海平面的成本，这将允许前所未有的系统数量被部署在世界各地的各种规模和资金水平的组织。在这里，我们建议通过设计一个独立的单元，从TRL 3到TRL 7，记录和处理所需的信号，以接近真实的时间输出潮汐水位，目标硬件和组装成本低于100英镑。我们的项目合作伙伴RNLI将测试和使用这些示范装置，最初是为了在一个潮间带堤道提供潮汐信息，该堤道有RNLI救援被涨潮搁浅的公众的历史。该技术不仅有可能在英国推广，而且有可能在全球推广，可能是开源设计和固件，以前所未有的价格和操作简单性彻底改变了收集潮汐和海平面数据的能力。
