Contribution

The paper introduces a new single-station, single-frequency IPS observation system and demonstrates its effectiveness through experimental observations.

Findings

Successful establishment of the SSSF system at Urumqi Observatory

First experimental observations of interplanetary scintillation with this system

Potential for improved solar wind measurement from single-station data

Abstract

The Sun affects the Earth's physical phenomena in multiple ways, in particular the material in interplanetary space comes from coronal expansion in the form of inhomogeneous plasma flow (solar wind), which is the primary source of the interplanetary medium. Ground-based Interplanetary Scintillation (IPS) observations are an important and effective method for measuring solar wind speed and the structures of small diameter radio sources. We discuss one mode of ground-based single-station observations: Single-Station Single-Frequency (SSSF) mode. To realize the SSSF mode, a new system has been established at Urumqi Astronomical Observatory (UAO), China, and a series of experimental observations were carried out successfully from May to December, 2008.
