Oral presentation

Under the framework of the project "Crustal Movement Observation Network of China" (CMONC), 3 VLBI stations located at Shanghai, Urumqi and Kunming are defined as the fiducial stations along with 260 continuous observing GPS stations.  In order to support domestic stand-alone geodetic observations with independent network based on Chinese VLBI stations, an upgrade to the correlator which was originally designed for the tracking of Chang’E 1 lunar satellite has been carried out since last year. The ongoing upgrade plan, which mainly covers the modification of correlator control system for compatibility of geodetic observing mode, the development of new software regarding format conversion and observable extraction, the implementation of MK5B playback capability, is presented in detail. Its current status and future prospect for space geodesy are also summarized.
