The use of different GPS standards or the implementation of GPS jamming and spoofing in India, Israel and Palestine, North Korea, Westchester County, New York, and Antarctica is driven by various strategic, security, and environmental factors
China
📌BeiDou Navigation Satellite System (BDS): China uses its own BeiDou system, which has been recognized as a global standard for commercial aviation and other applications. It provides both civilian and military services and is part of China’s strategy to achieve technological self-sufficiency and reduce dependency on the U.S. GPS.
📌Obfuscation Algorithm: The GCJ-02 system, also known as «Mars Coordinates,» uses an obfuscation algorithm that introduces random offsets to latitude and longitude coordinates. This is intended to prevent accurate mapping by foreign entities, which could be used for military or intelligence purposes.
📌Legal Framework: The Surveying and Mapping Law of the People’s Republic of China mandates that all geographic data must be processed using the GCJ-02 system. Unauthorized mapping or surveying activities are strictly prohibited and can result in severe penalties, including fines and legal action. Companies providing location-based services in China must obtain authorization from the Chinese government and use the GCJ-02 system. This includes purchasing a «shift correction» algorithm to align GPS coordinates correctly on maps.
📌Cold War Era: The use of a different coordinate system dates back to the Cold War era, aimed at frustrating foreign intelligence efforts. The GCJ-02 system continues to serve this purpose by ensuring that geographic data within China cannot be easily used for unauthorized purposes.
📌Daily Navigation: For users in China, this means that GPS devices and applications may show their location inaccurately on maps unless they use local services like Baidu Maps, which also employs an additional layer of obfuscation called BD-09.
📌Device Restrictions: Many GPS-enabled devices, including cameras and smartphones, have restrictions or modifications to comply with Chinese laws. This can include disabling geotagging features or using modified GPS chips that align with GCJ-02.
India
📌Indian Regional Navigation Satellite System (IRNSS): India has developed its own regional navigation system, known as NavIC (Navigation with Indian Constellation), to reduce dependency on foreign GPS systems like the U.S. GPS. This system ensures regional self-reliance, enhances positioning accuracy, and provides strategic advantages, especially for military operations.
📌Strategic Autonomy: The development of NavIC was partly motivated by the denial of GPS data by the U.S. during the Kargil War in 1999. NavIC provides India with an independent and reliable navigation system that can be used for both civilian and military purposes.
