Xinhua: The Compass Navigation Satellite System Is Unique

Sun Jiadong, an Academician at the Chinese Academy of Engineering, recently gave a speech at the Shanghai Expo. Sun is the Chief Architect and Designer of China’s self-developed GPS system – the Compass Navigation Satellite System (CNSS). Sun emphasized a unique feature that all other GPS systems do not have: CNSS allows ground devices to transmit short text messages to the satellites, thus establishing two-way communication. Sun also mentioned that although the CNSS is being built rapidly, the real world usage, or even preparation for usage, is minimal. Other than some central government branches, the entire domestic market is still asleep. The Chinese market is still dominated by foreign technologies and products. He believed that the general public needs to be educated about the Chinese space industry’s achievements.
