GPS Surface Reflection for Ionosphere and Sea State Determination

Abstract

In the past three to four years the recognition that GPS signals reflected from the earth s surface can yield useful geophysical information has led to aggressive and successful efforts to begin the exploitation of this phenomenon. Current research has demonstrated performance utilizing only the unencrypted C/A code at the L1 frequency of GPS. Information available when using both L1 and L2 is expected to enhance sea state and wind field retrievals and enable other important measurements. These enhancements will further improve performance of GPS as a powerful new tool for remote sensing from aircraft, balloon, and space platforms.
