Summary of China’s Alternative to GPS and its Implications for the United States

Core Content

This report provides an analysis of China’s Beidou satellite navigation system, its development, and its potential implications for the United States in the areas of security, diplomacy, and commerce. It highlights how Beidou, developed since 1994, is becoming a global alternative to GPS, with China aiming to achieve full global coverage by 2020.

Main Objectives of Beidou

• Military and Security: Beidou was initially developed due to concerns about reliance on foreign PNT systems, particularly after the 1995–1996 Taiwan Straits Crisis. It aims to provide China with a reliable, independent PNT system to support its military operations, especially in the Western Pacific region.
• Commercial and Economic: The system is now being promoted for commercial use, with the goal of building a domestic and global GNSS industry. China has invested heavily in the Beidou program and has implemented preferential policies to support its growth.
• Diplomatic and Strategic: Beidou is being used as a tool for international influence, particularly through its expansion into regions such as Southeast Asia and the Middle East under the "One Belt, One Road" initiative. It also enhances China's soft power and prestige on the global stage.

Key Features of Beidou

• Beidou currently has 23 satellites in medium Earth and geosynchronous orbits, providing regional coverage with accuracy under ten meters.
• It is expected to have 35 satellites by 2020, offering global coverage with improved accuracy.
• Beidou includes a short messaging service, allowing up to 120 characters to be sent between devices, which is a unique feature not available in GPS.
• The system is free for all users and is being integrated into a wide range of products, including smartphones, vehicles, and maritime equipment.

Market Development and Industry Growth

• The downstream GNSS industry is growing rapidly, with a global market value of $82.4 billion in 2014 and projected to grow at 7% annually through 2023.
• China’s GNSS industry has seen significant growth, with over 14,000 companies and 450,000 employees involved.
• The market penetration of Beidou in China is expected to reach 60% by 2020, indicating strong domestic adoption.
• China’s latecomer status in the GNSS market and fragmented industry structure suggest opportunities for economic gains in the future.

U.S. Implications

Military and Security

• If Beidou achieves global coverage by 2020, it will reduce China’s reliance on GPS for precision strike capabilities, potentially undermining U.S. military advantages.
• Beidou is likely integrated into China’s military systems, including ballistic and cruise missiles, and may be used as an alternative if GPS is denied.
• Security concerns include the potential for embedded malware in Beidou-equipped devices to track users, though experts suggest this is unlikely without the messaging function.
• The U.S. military is restricted from using non-allied PNT systems (such as Beidou) unless approved by the Secretary of Defense.

Diplomatic

• Beidou's global coverage could enhance China’s influence in international organizations like the International Maritime Organization and the International Committee on GNNS.
• China is using Beidou to expand its diplomatic reach, especially in the "One Belt, One Road" regions, by offering a free alternative to GPS.
• The establishment of differential ground stations in other countries could lead to diplomatic tensions, similar to the situation with Russia and GLONASS.

Commercial

• The trend toward multi-constellation devices (supporting GPS, GLONASS, Galileo, and Beidou) is expected to continue, increasing the importance of interoperability.
• U.S. companies may face challenges in the Chinese market due to preferential policies favoring local firms, such as subsidies, tax breaks, and early access to Beidou specifications.
• However, U.S. firms may have an advantage in the international market by offering multi-constellation compatibility.

Key Policies and Industry Support

• Domestic Mandates: China has mandated the use of Beidou in certain sectors, including buses, trucks, and fishing boats, with subsidies to encourage adoption.
• Government Support: The 2013 National Navigation Satellite Industry Medium- and Long-Term Development Plan aims to increase domestic market share to 60% by 2020.
• International Expansion: China has signed agreements with countries like Thailand, Brunei, Laos, and Pakistan to promote Beidou use. It is also in talks with Middle Eastern nations.
• Technological Cooperation: China and Russia have agreed to a joint venture for Beidou and GLONASS-compatible devices, indicating a strategic collaboration in the GNSS sector.

Conclusion

China’s Beidou system represents a significant challenge to the U.S. GPS monopoly, with implications across military, diplomatic, and commercial domains. As Beidou becomes more integrated into global markets, the U.S. must consider how to maintain its strategic advantage, ensure security, and adapt to the growing trend of multi-constellation GNSS devices. The system's unique features, such as the short messaging service, and its potential for international influence underscore the need for continued vigilance and strategic engagement from the U.S. government and private sector.
