Summary
Description
The DC-8 Dropsonde System (D8D) uses dropwinsonde and Global Positioning System (GPS) receivers to measure the atmospheric state parameters (temp, humidity, windspeed/direction pressure) and location in 3 dimensional space during the sonde's descent once each half second. Measurements are transmitted to the aircraft from the time of release until impact with the ocean's surface.
