"南京卫星协会"微信公众号19日发布《关于12月17日南京区域导航信号异常情况的技术性探讨分析》。全文如 下： 为澄清公众认知误区、解读技术原理与战略价值，南京卫星应用行业协会作如下说明： 一、离线地图无法解决本次导航异常问题 本次导航失灵的核心原因是GNSS卫星信号（含北斗、GPS）受到临时干扰压制，而非网络信号中断，因此下载 离线地图并无实际意义。 从技术原理来看： 1. 离线地图的核心功能是存储地理数据，仅解决"地图显示"问题，无法替代定位信号来源； 2. 手机导航需依赖GNSS卫星信号（至少4颗卫星）解算位置坐标，再将位置信息匹配至地图，定位信号与地图 数据是相互独立的两大系统； 2025年12月17日傍晚，南京部分区域出现导航定位异常现象，引发社会广泛关注。 各会员单位及社会各界： 3. 考虑到美国与欧盟的军事绑定特性，北约体系同样依赖GPS信号频段，这种频段兼容设计构建了重要的战略 威慑——任何针对北斗民用信号的干扰，都将同步影响GPS相关应用，从根本上遏制了恶意干扰的可能性，为 我国民用导航服务筑牢安全屏障。 3. 本次干扰精准针对北斗、GPS民用频段，导致定位信号无法被接收机识别，即便搭载离线 ...

Core Viewpoint - On December 17, 2025, a navigation signal anomaly occurred in Nanjing, affecting multiple navigation software systems and causing delivery delays for food delivery services due to the inability to access navigation data [12][18]. Group 1: Technical Analysis of the Navigation Anomaly - The core reason for the navigation failure was temporary interference suppression of GNSS satellite signals (including Beidou and GPS), rather than a network signal interruption, making offline maps ineffective [6][20]. - Offline maps only store geographic data and cannot replace the positioning signal source, as mobile navigation relies on GNSS satellite signals to calculate location coordinates [8][21]. - The interference specifically targeted the civilian frequency bands of Beidou and GPS, leading to the inability of receivers to recognize positioning signals, resulting in navigation drift and lack of data feedback [8][22]. Group 2: Strategic Significance of Beidou and GPS Compatibility - 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 [8][22]. - 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 [8][22]. - 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 applications [8][22]. Group 3: Resilience of Beidou Military Frequency - It is important to note that the signal anomaly only affected civilian GNSS frequency bands, while Beidou's military frequencies remained completely unaffected [9][23]. - The Beidou system employs a military-civilian frequency separation design, with military frequencies being exclusive and physically isolated from civilian bands [9][23]. - The military system is equipped with advanced anti-jamming technology and adaptive filtering algorithms, providing strong resistance to interference and deception, ensuring stable and reliable time-space services for national defense and emergency support [9][23].

Group 1 - Multiple navigation software systems experienced sudden failures, displaying "driving on a road with no data" [2] - Delivery riders reported issues with navigation in food delivery apps, leading to potential delays in deliveries [3] - Shared bike services also faced location errors, with users unable to lock bikes due to incorrect operational range displays [6] Group 2 - Platforms indicated that users could file complaints regarding order anomalies caused by location issues [6] - Customer service from Baidu Maps and Gaode Maps acknowledged the reported issues and stated they would relay the information to their engineering teams [6]

Core Viewpoint - Multiple navigation software systems in Nanjing experienced sudden failures, leading to significant disruptions in navigation services for users, including delivery riders and shared bike users [1][5]. Group 1: Navigation Software Issues - Users reported that navigation interfaces displayed "driving on a road with no data," causing confusion and delays in services [1]. - Delivery riders faced issues with embedded navigation in food delivery apps, resulting in potential delays in food delivery [1]. Group 2: Shared Bike Problems - Some shared bikes also encountered location errors, with users unable to lock their bikes after use, indicating operational range issues [5]. - A specific incident involved a user whose bike showed a drop-off location 57 kilometers away, highlighting the severity of the navigation errors [5]. Group 3: Company Responses - Various platforms acknowledged the issues and stated that users could file complaints regarding order anomalies caused by location errors [5]. - Meituan, a major player in the delivery service sector, confirmed that riders could appeal for resolutions if navigation issues led to delays [5].

Core Viewpoint - The integration of "lane-level advertising" in navigation software raises concerns about driving safety and potential violations of advertising laws, as it may distract drivers and obscure critical navigation information [1][2]. Group 1: Industry Concerns - The new advertising format may violate laws that prohibit interference with normal internet use and road safety regulations [1]. - The presence of large advertisements on navigation screens can lead to distractions, increasing the risk of accidents [1]. - The ethical implications of prioritizing commercial interests over public safety are significant, as even brief distractions can have severe consequences while driving [1]. Group 2: Recommendations for Navigation Software - Navigation software developers should take responsibility by optimizing ad placements to avoid disrupting the core user experience [2]. - Clear labeling of advertisements is essential to prevent confusion with navigation instructions, and options to close or skip ads should be provided to users [2]. - There is a need for enhanced internal regulation and a robust advertising review and complaint response mechanism to ensure compliance with public safety standards [2].
