Abstract. Ground-based observations can be used to provide
substantial support for Cluster/Double Star measurements and greatly enhance
the mission's scientific return. There are six Chinese ground stations
involved in coordinated cluster/Double Star and ground-based instrument
observations. Among them, the Chinese Zhongshan Station in Antarctica and
the Yellow River Station on Svalbard are closely magnetic conjugate and are
situated under the ionospheric projection of the magnetospheric cusp
regions, which, combined with satellite data, provide a perfect
configuration to conduct conjugate studies of cusp phenomena. In this paper
we present the ground-based instrumentation at these stations, discuss the
restriction which is applyed to the optical sites and present an overview of the occurrences for
conjunctions of these instruments with the spacecraft. Samples of data
products are given to illustrate the potential use of these instrumentations
in coordination with Cluster/Double Star measurements.
