Core Viewpoint - The navigation signal anomaly in Nanjing on December 17, 2025, was caused by temporary interference affecting GNSS satellite signals, specifically targeting the civilian frequencies of Beidou and GPS, rather than a network signal interruption [2][3][4]. Group 1: Technical Analysis - Offline maps cannot resolve the navigation anomaly as the core issue is the interference of GNSS signals, which cannot be substituted by stored geographic data [2][3]. - The navigation system requires signals from at least four GNSS satellites to determine location coordinates, indicating that positioning signals and map data are independent systems [2][3]. - The interference specifically targeted the civilian frequency bands of Beidou and GPS, leading to unrecognized positioning signals, resulting in navigation failures even with offline maps [2][3]. Group 2: Strategic Significance - The simultaneous impact on both Beidou and GPS signals during the anomaly validates the strategic foresight of China's Beidou system in planning its civilian frequency bands [3][4]. - The compatibility of Beidou's civilian signal (B1C band) with GPS's civilian signal (L1C band) not only breaks the spectrum resource blockade but also creates a strategic balance where interference with Beidou also affects GPS [3][4]. - This design serves as a deterrent against malicious interference, as any disruption to Beidou's civilian signals will simultaneously impact GPS applications, thereby enhancing the security of China's civilian navigation services [3][4]. Group 3: Military Frequency Resilience - The signal anomaly only affected civilian GNSS frequencies, while Beidou's military frequencies remained unaffected due to their separation from civilian bands [4][5]. - The military system employs advanced anti-jamming technologies, ensuring robust resistance to interference and deception [4][5]. - The independence and resilience of Beidou's military frequencies provide stable and reliable time-space services for national defense and emergency support, unaffected by the civilian signal disruptions [4][5]. Group 4: Industry Response - The Nanjing Satellite Application Industry Association will continue to monitor industry developments and share professional knowledge on satellite navigation technology to enhance public understanding [4][5]. - The association encourages relevant enterprises to participate in discussions and will waive membership fees to facilitate communication between businesses and the government [5].

Core Viewpoint - The article discusses the navigation signal anomalies in Nanjing on December 17, 2025, clarifying the technical reasons behind the issue and emphasizing the strategic significance of the Beidou and GPS systems' compatibility [2][5]. Technical Analysis - Offline maps cannot resolve the navigation anomaly as the core issue is the temporary interference of GNSS satellite signals (including Beidou and GPS), not a network signal interruption [3]. - The core function of offline maps is to store geographic data, which only addresses the "map display" issue and cannot replace the positioning signal source [4]. - Mobile navigation relies on GNSS satellite signals (at least 4 satellites) to calculate position coordinates, and the positioning signal and map data are independent systems [4]. - The interference specifically targeted the civilian frequency bands of Beidou and GPS, preventing the positioning signal from being recognized by receivers, leading to issues like positioning drift and lack of data feedback, making effective navigation impossible [4]. Strategic Significance - The simultaneous impact on Beidou and GPS signals during the anomaly validates the forward-looking strategic vision of China's Beidou system's civilian frequency band planning [5]. - The international satellite navigation spectrum resources follow a "first come, first served" rule, with GPS having occupied core L-band resources early on, leaving limited quality spectrum for Beidou [6]. - Under the framework of the International Telecommunication Union, the compatibility of Beidou's civilian signal (B1C band) with GPS's civilian signal (L1C band) breaks the spectrum resource blockade and creates a strategic balance where interference with Beidou also affects GPS [6]. - Given the military ties of the U.S. and EU, NATO systems also rely on GPS signals, making this frequency compatibility a significant strategic deterrent against malicious interference [6]. Military Frequency Resilience - The signal anomaly only affected civilian GNSS frequency bands, while Beidou's military frequency remains unaffected [7]. - Beidou employs a military-civilian frequency separation design, with military frequencies being exclusive and confidential, physically isolated from civilian bands [7]. - The military system incorporates full digital anti-jamming technology and adaptive intelligent filtering algorithms, enabling precise identification and filtering of interference signals, thus possessing strong anti-jamming and anti-deception capabilities [7]. - The independence and anti-jamming capabilities of Beidou's military frequency provide stable and reliable time-space services for national defense security and emergency support in critical areas, unaffected by the civilian signal interference [7].
