Using GPS Multipath for Snow-Depth Estimation
In this month’s column, we look at a technique that uses interference fringes generated by signals arriving at an antenna directly from GPS satellites and those reflected by snow surrounding the antenna to measure its depth and how it varies over time. GPS for measuring snow depth; who would have thought? read more
