Abstract
The Global Positioning System Occultation Sensor (GPSOS) is a precision GPS instrument carried by the NPOESS spacecraft. It measures primarily the electron density profile and scintillation parameters of the ionosphere. The measurements are obtained by tracking signals of GPS satellites that are observed to rise or set through the atmosphere while recording the signal amplitude and phase.
