Reflections on Development of Queqiao Communication， Navigation，and Remote Sensing Integrated Constellation System

Abstract

First，the development trends of lunar communication，navigation and remote sensing（CNR）systems in the United States，Russia，Europe，Japan，and multilateral organizations were investigated，deriving insights for future development. Next， the current status of China’s lunar CNR system was analyzed and development needs from multiple perspectives，including supporting major engineering projects，enabling cis-lunar economic development，contributing to building China into a space power，safeguarding space assets，and promoting deep space international cooperation，were examined. It was proposed that China should accelerate the detailed design and key technology development of the Queqiao Communication，Navigation，and Remote Sensing Integrated Constellation System（QCNRSICS），actively advance international cooperation under Chinese leadership，and enhance its global standing. On this basis，a development concept for China’s QCNRSICS was proposed，covering construction objectives，overall architecture and development phases. Finally，nine critical technologies urgently requiring resolution for future constellation construction were identified.
