Development and testing of the GISMOS instrument

Abstract

The GNSS Instrument System for Multistatic and Occultation Sensing (GISMOS) is a new remote sensing system in development for the HIAPER Gulfstream V (GV) aircraft. This system is designed to use occulted and reflected Global Navigation Satellite System (GNSS) signals to retrieve tropospheric water vapor, ocean surface roughness and soil moisture during long duration, high altitude, flights. This paper summarizes the design and ground testing of GISMOS as well as the current flight test schedule.
