GPS radio occultation measurements of the ionosphere from CHAMP: Early results
[1] The paper deals with initial analyzes of radio occultation measurements of the ionosphere carried out on board the CHAMP satellite since 11 April 2001. The accuracy of the operationally retrieved electron density profiles has been estimated by comparing with independent measurements. The derived ionospheric key parameters such as f0F2 and hmF2 agree with a standard deviation of 18 and 13%, ...
متن کاملOn the ionosphere calibration in GPS radio occultation measurements
Elimination of the ionospheric contribution to atmospheric delays in GPS radio occultation measurements is a key issue in the retrieval of accurate pressure and temperature profiles above the tropopause. The traditional so-called “ionosphere-free” combination of the L1 and L2 phase paths, eliminating the first-order ionospheric effects, is not sufficient because of the nonnegligible bending of ...
متن کاملIonosphere of Callisto from Galileo radio occultation observations
[1] An ionosphere has been detected at Callisto by the Galileo spacecraft, using the radio occultation technique. There were four usable occultations by Callisto, providing eight observation opportunities, all equatorial and near the terminator (entry and exit observations). Detectable electron densities were obtained from six of the eight opportunities. It was found that a detectable ionospher...
متن کاملAtmospiieric Profiles from Radio Occultation Measurements of Gps Satellites
Atmospheric profiles can be retrieved with techniques utilizing measurements of the propagation delay of signals from Global Positioning System (GPS) satellites observed by one or more receivers in low earth orbit. The. observations are made in a limb-sounding geometry when the radio path between the transmitter and receiver passes through the atmosphere. The various componen~s of the microwave...
متن کاملAnalysis of Gravity Waves from Radio Occultation Measurements
In the height range 10-30 km atmospheric gravity waves lead to periodic perturbations of the background temperature field in the order of 2-3 K, which can be resolved in temperature profiles derived from radio occultation measurements. Due to the spherical symmetry assumption in the retrieval algorithm and the low horizontal resolution of the measurement weakening in the amplitude and phase shi...
