Learn about NASA’s new system of small satellites that could help scientists better understand and forecast tropical storms, in this article from NOVA Next. NASA’s Cyclone Global Navigation Satellite System (CYGNSS) is an experimental mission to demonstrate how a network of small satellites with GPS technology could improve storm observations. CYGNSS consists of eight satellites that use GPS signals to monitor wind speeds over tropical oceans. This system will allow scientists to learn more about how storms develop and intensify because it can penetrate heavy clouds and observe locations more frequently than traditional weather satellites, which use higher frequency radio waves. Small satellite systems such as CYGNSS can also be developed more quickly and at less cost than traditional weather satellites. This resource is part of the NOVA Next Collection.
