<p>In the wave of global technological competition, satellite internet has become a strategic high ground. With the rapid deployment of overseas constellations such as Starlink and the steady progress of domestic programs such as China SatNet, global satellite internet construction is experiencing an unprecedented boom. In this process, prototype validation of LEO satellite payloads has become a key step in ensuring stable on-orbit operation and shortening development cycles, and market demand for related validation platforms is surging.</p>
<p>Developing LEO satellite payloads places extremely high demands on communication technology, including direct sampling and transmission of Ku/Ka-band IF signals, wideband satellite transmit/receive capability and on-board real-time signal processing. To fully validate these complex functions on the ground, research institutions urgently need highly realistic and flexible prototype validation platforms. Such platforms must support ultra-wideband RF signal processing as well as powerful FPGA logic resources and real-time data interaction to emulate real satellite-ground link conditions.</p>
<p>Seizing the opportunities of commercial space, Jieshi Zhitong has made forward-looking arrangements in satellite communication ground terminals and spaceborne payload prototype validation platforms. Leveraging core technologies in high-speed data acquisition, RFSoC modules and signal processing, the company has released several prototype validation systems designed specifically for satellite internet R&amp;D. These systems support multi-channel, wideband RF signal acquisition and generation, efficiently completing hardware-in-the-loop testing and performance evaluation of payload algorithms while greatly reducing the risk and cost of satellite payload development.</p>
<p>As a member of the China Radar Industry Association, Jieshi Zhitong has established joint R&amp;D programs with a number of military research institutes and aerospace research organizations. Facing the broad market prospects of satellite internet, the company will continue to deepen satellite-ground integrated communication technology and iterate its payload validation platforms, contributing core strength to the rapid development of China's commercial space industry.</p>
