Jiangsu Radio, TV and Satellite Earth Station was officially put into operation on December 28, 1997. Jiangsu Satellite TV transmitted through a 5A transponder located on the Asiasat-2 satellite at an altitude of 100.5 ° East with an up-link frequency of 6052 MHz. It adopts a single-carrier single-carrier mode (SCPC), OPSK adjustment, DVB standard digital television compression, radio programs. Equipment for the introduction of foreign technology in the leading domestic level. Downstream frequency of 3827MHZ, program coverage up to 42.4% of the global surface area. Jiangsu Satellite TV starred in the radio and television industry in Jiangsu on a new level. Less than a year since the launch of the satellite earth station, but encountered two times of eclipses and Japan.
