This special issue is devoted to the GPS radio occultation (RO) technique, which holds a great promise for investigating the natural processes of the Earth’s atmosphere and ionosphere on a global scale with high vertical resolution and accuracy. The results obtained thus far by means of the GPS RO technique have generated much interest in several geophysical disciplines including geodesy, meteorology, climatology, and ionospheric physics.

The main idea of the RO technique appeared in 1964 as part of a proposed scheme for the bistatic study of the planetary atmospheres and surfaces. RO experiments were included in the NASA’s planetary exploration missions to Mercury, Venus, Mars, Jupiter, Saturn, Neptune and some of their satellites, and are included in plans for future missions. During 1972–1985, the Soviet’s interplanetary missions also provided RO experiments for studying the ionosphere and atmosphere of Mars and Venus. In addition, since 1975, the RO method has been applied to the...
