GPS Occultation Sensor GPSOS
Measures the refraction of radiowave signals from the GPS and Russia’s Global Navigation Satellite System (GLONASS) to characterize the Ionosphere. Primary instrument for electron density and ionospheric profiles. Secondary measurements for tropospheric temperature and humidity profiles.
Multiple GPS receivers to measure electron density profile
with vertical coverage 10km within 100km of E/F peaks
