12月19日，南京卫星协会发布"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"，内容如下： 各会员单位及社会各界： 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。 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； 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，即便搭载离线地图，也因缺乏位置数据源出现定位漂移、 无数据反馈等问题，无法实现有效导航。（离线地图更适用于公海荒漠深山等有卫星定位信号、无通信网络信号的区域）。 二、北斗与GPS民用频段兼容的战略意义得到验证 本次异常中北斗与GPS信号同步受影响，恰恰印证了我国北斗系统民用频段规划的前瞻性战略眼光： 1. 国际卫星导航频谱资源遵循"先到先得"规则，GPS早年间占据了L频段核心资源，北斗立项时优质频谱已所剩无几； 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 ...
