NASA Awards Orbital Sciences Launch Services Contract for Hurricane-Forecasting CYGNSS Mission

The CYGNSS mission is comprised of eight Low-Earth Orbiting (LEO) spacecraft (S/C) that receive both direct (white lines) and reflected (blue lines) signals from GPS satellites. The direct signals pinpoint LEO S/C positions, while the reflected signals respond to ocean surface roughness, from which wind speed is retrieved. GPS bi-static scatterometry measures ocean surface winds at […]
