The first regular domestic geodetic VLBI observing program in China, dedicated to the project Crustal Movement Observation Network of China (CMONOC), has been carried out from the year 2011 onward, with participation of Shanghai, Kunming and Urumqi stations. In order to support the data correlation of the geodetic observations, the Shanghai correlator system, which was originally designed for the tracking of the Chinese lunar satellites, has been upgraded to be compatible with geodetic sub-array mode and Mark 5B data format. The whole system is now an operational, fully functional and internationally compatible system. In order to connect with the global terrestrial reference frame more accurate, Kunming has also begun to join in a few IVS sessions on annual basis. It is anticipated that the wider bandwidth observations (16ch$ imes$32MHz/ch) by taking advantage of CDAS and wider frequency coverage at X band (8.2-9.0GHz) will be operational in the near future to reduce the measurement error.
