<p>强大的定向干扰导致周三在中国一座主要城市的卫星导航系统，包括 GPS 和北斗，暂时失效，行业协会周五表示。\n 此次干扰影响了南京的用户，这座城市人口近 1000 万，是江苏省的省会，干扰发生在周三下午 4 点到晚上 10 点之间。依赖卫星定位的汽车导航、外卖、打车和无人机控制应用在此期间经历了 “系统性异常”。\n 用户报告称位置严重漂移，完全失去了道路数据，影响了日常生活和经济。干扰使得依赖位置的服务瘫痪，打车订单下降了 60%，外卖效率下降了 40%，而共享单车系统报告位置错误高达 57 公里（35 英里），当地媒体称。\n 根据南京卫星应用产业协会的技术分析，此事件是由于全球导航卫星系统（GNSS）信号的 “临时干扰和抑制” 造成的，而非移动网络故障。\n“干扰特别针对北斗和 GPS 的民用频段，阻止接收器正确识别定位信号，” 该协会在社交媒体上表示。\n“因此，有效导航变得不可能。即使是配备离线地图的设备也因缺乏有效的定位源而遭遇位置漂移和完全缺乏数据反馈。”\n\n\n 该协会没有提到可能实施干扰的主体或目的。\n“如果此次导航干扰是由于在重大事件期间实施的临时信号控制措施造成的，这种行为被视为行业安全标准协议，” 它表示，暗示可能发生了高安全性事件。\n“相关信号在事件结束后已经逐渐恢复正常。”\n 它补充说，信号异常仅影响了民用 GNSS 频段，而北斗的军事频率则 “完全未受干扰”。\n 根据该协会，北斗的军事和民用频率在物理上是分开的，军事频段采用专用加密和抗干扰技术，以确保国家防御和安全的可靠服务。\n 相比之下，GPS 的军事和民用信号共享相同的载波频率，尽管它们通过不同的加密和频谱调制技术在功能上是分开的。\n 该协会表示，民用北斗和 GPS 信号在此次事件中同时受到干扰是 “远见战略规划的确认”。\n 它解释说，在中国与北约之间发生冲突的情况下——北约依赖美国军方操作的 GPS——试图干扰北斗也会干扰 GPS，从而形成战略制衡。\n 它指出，使北斗的民用频段与 GPS 兼容的决定创造了显著的战略威慑：“任何针对北斗民用信号的故意干扰都会同时干扰依赖 GPS 的应用，从而从根本上威慑恶意干扰，并为中国的民用导航服务建立坚固的安全屏障。”\n 卫星干扰在军事冲突中被使用，例如乌克兰战争，以切断通信和削弱精确度。据报道，伊朗在与以色列和美国的 12 天战争中经历了 GPS 信号干扰后，考虑转向北斗导航系统，这场战争导致其军事和核设施遭受重大损失。\n</p>

<p>在中国南京发生了一起针对性的干扰事件，干扰了 GPS 和北斗卫星导航系统，影响了打车和配送等民用服务。干扰针对民用频段，暗示这是一起高安全性的事件。军事频段未受到影响。该事件突显了战略规划的重要性，因为干扰北斗也会影响 GPS，形成战略威慑。这一干扰与乌克兰战争等冲突中看到的军事战术相一致</p>

<p>Powerful, targeted jamming caused a temporary blackout of satellite navigation systems, including GPS and BeiDou, in a major Chinese city on Wednesday, an industry association said on Friday.\nThe disruption affected users in Nanjing, a city of nearly 10 million people and capital of the eastern province of Jiangsu, between 4pm and 10pm on Wednesday. Car navigation, food delivery, ride-hailing, and drone control apps relying on satellite positioning experienced a “systemic anomaly” during the period.\nUsers reported severe position drifting and total loss of road data, affecting daily life and the economy. The disruption paralysed location-dependent services, causing ride-hailing orders to plummet by 60 per cent and delivery efficiency to drop by 40 per cent, while bike-sharing systems reported location errors of up to 57km (35 miles), according to local media.\nThe incident was caused by “temporary interference and suppression” of global navigation satellite system (GNSS) signals, rather than mobile network failures, according to a technical analysis by the Nanjing Satellite Application Industry Association.\n“The interference specifically targeted the civilian frequency bands of both BeiDou and GPS, preventing receivers from correctly identifying positioning signals,” the association said on social media.\n“Consequently, effective navigation was impossible. Even devices equipped with offline maps suffered from location drift and a complete lack of data feedback due to the absence of a valid positioning source.”\n\n\nThe association did not mention who might have carried out the jamming, or for what purpose.\n“If this navigation disruption was caused by temporary signal control measures implemented for security during a major event, such actions are considered standard industry safety protocols,” it said, hinting at the possibility of a high-security event having taken place.\n“Relevant signals have already gradually returned to normal after the event concluded.”\nIt added that the signal anomaly had affected only civilian GNSS frequency bands and the BeiDou military frequencies had remained “completely unaffected” by the interference.\nBeiDou’s military and civilian frequencies are separated physically, and the military bands employ dedicated encryption and anti-jamming technologies to ensure reliable service for national defence and security, according to the association.\nIn contrast, the military and civilian signals of GPS share the same carrier frequencies, though they are functionally separated through distinct encryption and spectral modulation techniques.\nThe association said the fact that civilian BeiDou and GPS signals had been simultaneously disrupted in the incident was a “confirmation of farsighted strategic planning”.\nIt explained that in the event of a conflict between China and Nato – which relies on GPS operated by the US military – an attempt to jam BeiDou would also jam GPS, creating a strategic check and balance.\nIt noted that the decision to make BeiDou’s civilian frequency band compatible with GPS created a significant strategic deterrent: “Any deliberate interference targeting BeiDou’s civilian signals would simultaneously disrupt GPS-dependent applications, thereby fundamentally deterring malicious jamming and building a robust security barrier for China’s civilian navigation services.”\nSatellite jamming has been used in military conflicts, such as the Ukraine war, to sever communications and undermine precision. Iran has reportedly considered shifting to the BeiDou navigation system after experiencing GPS signal disruptions during its 12-day war with Israel and the US in June, which resulted in major losses at military and nuclear facilities.\n</p>
