  skos:definition """The Delay Doppler Mapping Instrument (DDMI) flies aboard each of the 8 spacecraft of the CYGNSS constellation and is an L-band receiver designed to receive direct signals from GPS satellites as well as signals reflected off the ocean surface. The direct signals are used to pinpoint the location of the CYGNSS observatory (of which there are 8 unique spacecraft observatories), while the reflected signals correspond to ocean surface roughness, from which wind speed is estimated using a Geophysical Model Function (GMF).
