Technology Demonstration of Soil Moisture  Monitoring with Reflected Global Navigation  Satellite System ( GNSS ) Signals — PI: Dr. Sunil  B. Bisnath. Measurements of land surface soil  moisture are vital for analyzing melting tundra and permafrost in  our changing climate. They are also of great interest to a  wide variety of fields, e.g., mining, farming and urban development. The Global Navigation  Satellite System Reflectometry ( GNSS-R ) technique provides insight into certain  surface conditions. Making use of freely available GNSS signal  reflections over land for remote sensing would represent a significant step  forward. This project aims to develop a prototype GNSS-R receiver capable of  making customizable surface reflection measurements from space of surface soil  moisture content and variation, using signals from the many GNSS satellites  currently in orbit.
