Abstract: This article is based on the construction of the HD system of the Ningxia Earth Station, and explores the feasibility of IPization construction of HD/Ultra HD Earth Stations. The transmission before modulation in the uplink system adopts an IP switch+SDN architecture, core products such as encoders, scrambling multiplexers, modulators, up converters, and high power amplifiers can use independent products, provided construction direction for the uplink system of HD/Ultra HD earth stations.
