Chinese Academy of Engineering Academician Liu Jingnan: The ability to control time and space is the "strategic cornerstone" of national security, and we cannot hand over our "lifeline" to others.

On April 1st, Securities Times interviewed Liu Jingnan, academician of the Chinese Academy of Engineering, professor of Wuhan University, and director of the National Satellite Navigation System Engineering Technology Research Center. Liu Jingnan stated that the importance of the spatio-temporal information industry is reflected in three aspects: First, spatio-temporal information is the "metric" of the digital economy. Calling for ride-hailing, placing orders on e-commerce platforms, watching short videos based on local recommendations... more than 80% of the data we generate each day is tagged with spatio-temporal information. Second, the spatio-temporal foundation is the "infrastructure" that serves and empowers emerging industries. Low-altitude economy, autonomous driving, artificial intelligence, these exciting emerging industries all have a common underlying demand for high-precision, high-reliable spatio-temporal positioning information. Third, spatio-temporal capabilities are the "strategic cornerstone" of national security. Spatio-temporal information is related to national defense security, economic security, and public security. If a country's critical infrastructure, such as power grids, communication networks, financial systems, transportation, etc., all rely on another country's satellite navigation and timing services, it is equivalent to handing over its "lifeblood" to others.
