Quantum navigation system. According to foreign media reports, a foreign defense company recently announced that its developed quantum navigation system has completed field testing. During the testing period, the system was able to continuously provide high-precision positioning services for ground equipment. It is reported that this quantum navigation system has GPS like positioning function and significant advantages. It adopts a passive operation mode, making it difficult to detect and not subject to interference or deception, and is expected to provide new options for navigation in both defense and civilian fields. Analysis suggests that the system is capable of meeting the growing navigation demands in fields such as aerospace, field operations, and autonomous driving. For example, in the field of national defense, this system can enhance the accuracy and concealment of combat operations during the execution of tasks such as operations or reconnaissance; In the civil field, it can optimize transportation operations and provide reliable positioning support for the auto drive system, thus promoting the development of related industries.
