Abstract

The Physical Research Laboratory has been engaged in setting up a three-station radio observatory operating at a frequency of 103 MHz in western India for exploration of the heliosphere by the interplanetary scintillation (IPS) technique. The three radio telescopes are separated by about 200 km from each other and are being operated as 'transit' telescopes in correlation interferometer mode with excellent relative time accuracy. IPS observations of scintillating radio sources made over a wide range of their solar elongations permit determination of not only the solar wind velocity at different heliolatitudes and other traveling interplanetary disturbances, but also the structure of the heliosphere up to a distance of about 1.0 AU.
