It provides both civilian and military services and is part of Chinaโs strategy to achieve technological self-sufficiency and reduce dependency on the U.S. GPS.
๐Obfuscation Algorithm: The GCJ-02 system, also known as ยซMars Coordinates,ยป 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.
๐Legal Framework: The Surveying and Mapping Law of the Peopleโs 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 ยซshift correctionยป algorithm to align GPS coordinates correctly on maps.
๐Cold 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.
๐Daily 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.
๐Device 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.
๐Indian 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.
๐Strategic 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.
๐GPS Jamming and Spoofing: Israel uses GPS jamming and spoofing as defensive measures to protect against potential attacks from adversaries like Hezbollah and Iran. This jamming can disrupt enemy navigation systems and precision-guided weapons, but it also affects civilian GPS services, causing inaccuracies in location data for apps like Google Maps and Uber.

Inaccurate mapping systems can significantly impact daily navigation in various regions around the world, including China, India, Israel and Palestine, North Korea, Westchester County in New York, and Antarctica.
Misalignment of Maps and GPS Data
๐Offset Issues: The GCJ-02 system introduces random offsets to latitude and longitude, ranging from 50 to 500 meters. This results in GPS coordinates (based on the global WGS-84 system) not aligning correctly with Chinese maps, which use GCJ-02.
๐Practical Impact: For users, this means that GPS devices and applications may show their location inaccurately on maps. For example, a GPS coordinate might place a user in a different part of a city than their actual location.
Challenges for Foreign Mapping Services
๐Google Maps: Google Maps in China must use the GCJ-02 system for street maps but uses WGS-84 for satellite imagery, causing visible misalignments between the two. This discrepancy can make navigation difficult for users relying on Google Maps.
๐Other Services: Similar issues affect other foreign mapping services, which must either comply with GCJ-02 or face inaccuracies. Unauthorized mapping or attempts to correct the offsets without approval are illegal.
Local Solutions and Workarounds
๐Chinese Apps: Local apps like Baidu Maps and WeChat use the GCJ-02 system and often provide more accurate navigation within China. Baidu Maps even uses an additional layer of obfuscation called BD-09.
๐Conversion Tools: Several open-source projects and tools exist to convert between GCJ-02 and WGS-84 coordinates, helping developers and users mitigate some of the navigation issues.
Legal and Security Implications
๐Regulations: The Chinese government enforces strict regulations on geographic data to protect national security. Unauthorized mapping activities can result in severe penalties, including fines and legal action.
๐Device 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.
