Core Viewpoint - The core issue of the navigation signal anomaly in Nanjing on December 17 is attributed to temporary interference suppressing GNSS satellite signals, including BeiDou and GPS, rather than a network signal interruption [1] Group 1: Technical Analysis - The offline maps are ineffective in resolving the navigation anomaly, as the core problem lies in the GNSS satellite signal interference [1] - Both BeiDou and GPS signals were simultaneously affected, highlighting the strategic foresight in the planning of China's BeiDou system for civilian frequency bands [1] Group 2: Impact on Military and Civilian Use - The signal anomaly only impacted civilian GNSS frequency bands, while the military frequency of BeiDou remained completely unaffected [1]
