BeiDou: China’s GPS Challenger Takes Its Place On World Stage – Analysis​

July 6, 2022

Global navigation satellite systems (GNSS) provide a service many people take for granted. The GNSS applications people use fall into five major categories: location (determining a position), navigation (getting from one location to another), tracking (monitoring movement of people or objects), mapping (creating maps of the world), and timing (calculating time). Generally, a GNSS has a constellation of at least 24 satellites in medium-Earth orbit (about 12,550 miles high) spread out around the world to deliver global service.1 Such GNSS capabilities are considered so essential that countries and alliances are simply unwilling to rely on each other for a system that is now considered indispensable to sovereignty. GNSS supports millions of applications that track and analyze our everyday lives—from farming, to finance, to reliable Internet. Simply put, it has become a vital service.

GNSS were created almost 50 years ago when U.S. scientists pioneered a global positioning system (GPS). Today, four countries operate GNSS: the United States has GPS, Russia has GLObal NAvigation Satellite System (GLONASS), the European Union (EU) has Galileo, and China has the BeiDou Navigation Satellite System, usually referred to as “BeiDou.” Japan and India have regional systems, and even the United Kingdom is planning for its own constellation since leaving the EU.2

With the launch of its final satellite to reach full system capability, China completed BeiDou in June 2020, and much has been made of the system and its features thus far.3 But BeiDou is only the latest GNSS to come online since the United States developed GPS. Although much speculation and debate exist, it remains unclear if BeiDou will matter to the United States and other Western powers. An examination of the various types of GNSS reveals differences in their development and military use/adoption as well as in international response to them. This closer look sheds light on the likely impact of BeiDou, as it considers the system’s integration with China’s Belt and Road Initiative (BRI), the relationship with Russia and the EU, security concerns, and relative accuracy. A careful analysis of BeiDou and the multi-GNSS environment reveals that, although BeiDou does not represent a technological coup for the Chinese, it does constitute an incremental erosion of American technical prestige by presenting a viable alternative to GPS in an important sector that billions of people around the world use every day.


China decided to develop BeiDou after the 1995–1996 Taiwan Strait Crisis, when an unexpected disruption in GPS caused the People’s Liberation Army to lose track of its ballistic missiles fired over the Taiwan Strait.34 China decided it could not afford to repeat such an incident and needed to invest in its own satellite-based PNT system.35 Even though China had a standing agreement with Russia to use GLONASS for basic navigation and GLONASS-guided munitions, China persisted with its plan to develop BeiDou.36 Given China’s emergence on the world stage and desire for recognition, this move is not surprising; Beijing desires a GNSS that it can maintain complete control of.

BeiDou is currently on its third generation of satellites. In 2000, BeiDou-1 was completed and began to provide PNT services to China only; in 2012, BeiDou-2 was completed and began to provide service to the Asia-Pacific region.37 The third and final phase of the project, BeiDou-3, hit a milestone in 2018 when it began offering services globally. BeiDou-3’s preliminary system was completed with the launch of its final satellite in June 2020.38 BeiDou uses two different general types of service: Radio Navigation Satellite Service (RNSS) and Radio Determination Satellite Service (RDSS). RNSS functions like other GNSS and was designed to have similar performance. RDSS is significantly different: A ground station using signals from the BeiDou satellites calculates a user’s position. The RDSS approach allows for large-volume message communication and extended coverage.39 However, any employment of BeiDou where ground stations are located allows the Chinese government to monitor a user’s location. Both RNSS and RDSS allow the user to send communications via short message service (SMS), a feature unique among the GNSS to BeiDou. The operational implications for such a feature mean that the Chinese government has a system to broadcast messages to any compatible BeiDou user in the world. The potential applications for such a feature are limitless.

Although every GNSS broadcasts a more accurate signal for only military and government use, BeiDou uniquely provides these sensitive users with information about the status and current accuracy of the navigation signal in real time.40 BeiDou has been widely integrated with the Chinese military since at least 2014, and the military uses the SMS feature heavily; it is ideal for communicating among units and headquarters in remote locations. The military has also integrated BeiDou into its precision-guided munitions, including ballistic and cruise missiles.41 Although China promotes BeiDou worldwide, especially within the Asia-Pacific region and BRI countries, its most developed BeiDou relationship is with Pakistan. As of December 2018, as part of a military cooperation agreement with China, Pakistan was the only country permitted to use the BeiDou restrictive service.42 Pakistan also signed a first-of-its-kind agreement with China in 2013 to install five BeiDou ground augmentation stations and one processing center, allowing greater accuracy in the country.43

On July 9, 2019, the Consultative Assembly of Saudi Arabia agreed on a draft memorandum of understanding to cooperate on the military use of BeiDou. The Saudi Ministry of Defense and the Equipment Development Department of China’s Central Military Commission signed the memorandum. This agreement comes after the Second China-Arab States BeiDou Cooperation Forum, which took place April 1–2, 2020, in Tunis, Tunisia. Before this event, the two countries reportedly agreed in March 2019 to “deepen military collaboration to jointly promote regional peace and stability.”44

China aggressively markets BeiDou to the private sector, especially as part of its BRI in Asian countries. In 2013, electronics leaders Qualcomm and Samsung collaborated to bring to market the first smartphones that included BeiDou; their smartphones and tablets were also the first to track three GNSS—GLONASS, GPS, and BeiDou.45 Together, this marked an important milestone for inclusion of BeiDou in the world consumer electronics market as well as for the synthesis of multiple PNT systems on handheld devices. BeiDou made the transition to consumer electronics faster than did GLONASS, having entered the market at a later point in the maturity of handheld electronics after two other GNSS (GPS and GLONASS) had established demand and precedent. Smartphones began using Galileo in 2016, and it is now common for consumer devices to track using multiple GNSS.46 Clearly, the consumer smart-electronics market saw value in utilizing other sources of PNT.

By the end of 2019, more than 70 percent of Chinese smartphones utilized BeiDou for positioning services—with a purported $57 billion in goods and services tied to the capability. China aims to use BeiDou, together with its fifth-generation cellphone technology, to dominate the market for telecommunications services, which China envisions will include next-generation technologies such as autonomous vehicles. Agreements to use BeiDou under China’s expansive BRI have already been signed with 120 partners.47 More than 30 countries, 400 million users, and 6.5 million vehicles use BeiDou.48 Without abandoning GPS, thanks to multi-GNSS radio chipsets, the world has also embraced BeiDou.


In addition to being a full-fledged GNSS, BeiDou is a critical piece in the digital architecture of China’s BRI. Consequently, China aggressively promotes BeiDou as part of its complete system of wares when it markets to other countries. China has indeed seen a surge of activity regarding BeiDou within the international community in the past few years. Security professionals should anticipate more countries adopting the system or coordinating with China now that BeiDou has achieved FOC.

Somewhat surprisingly, Russia is one of those countries that, despite having GLONASS, signed a joint GLONASS-BeiDou cooperation and compatibility agreement in 2015. This agreement was followed by a joint Chinese-Russian Silk Road Project that “marked the first, large-scale Sino-Russian effort to share, compare, and systematize satellite data” in 2017.49 By 2018, China and Russia were able to agree on the same chipset, giving users “access to the total of GLONASS-BeiDou zone coverage, which spans across 40 functioning satellites” and “encompasses the Earth’s entire surface,” according to GLONASS President Alexander Gurko.50 This move created a technological interdependency between two countries that have long struggled to maintain a peaceful border.

As a GNSS, BeiDou offers a slight improvement over GLONASS in terms of accuracy and availability. When considered as an entire system with additional ground antennas, signal post-processing, and communications, BeiDou is superior to GPS, GLONASS, and Galileo. Time will tell if integration with the BRI makes BeiDou more—or less—appealing to the world.

China’s relationship with the EU’s Galileo is somewhat murkier. China’s aborted participation in Galileo not only gave China BeiDou’s technological underpinnings but also left it seemingly unencumbered by any fallout on the international scene. Comparing the military impact of Galileo and BeiDou directly is difficult because Galileo is civilian-run and not well-suited or marketed for weapons systems. Galileo is not part of a broad infrastructure initiative like BeiDou is with the BRI. The EU provides Galileo to the global community without significant installations in foreign territory or a political agenda; it does not seem interested in marketing Galileo as a replacement for GPS but rather views Galileo as an augmentation or “kinder” alternative (per marketing). In the commercial domain, Galileo, much like BeiDou, has been widely accepted in the international marketplace for incorporation into both hardware and software applications. This level of incorporation will likely soften any political or economic impact from BeiDou on the United States simply by broadening the competition.

Unlike the Huawei 5G cellular network—another part of China’s BRI that the U.S. Government is actively campaigning against in partner nations due to security concerns—BeiDou does not pose an obvious security threat to users outside of Asia, where BeiDou ground stations are installed. Although concerns abound that the navigation signal may be able to install malware into a user’s device, such possibility is highly unlikely, according to industry experts. However, malware could be installed through the BeiDou receiver chip, especially in a Chinese-manufactured device, or if the device uses the two-way transmission messaging service. Two-way transmission is necessary for BeiDou to monitor the location of the user and provide enhanced, post-processed position accuracy. Furthermore, most smartphone manufacturers are not expected to utilize BeiDou’s SMS functionality because the service requires a large amount of power and is not practical in a nondedicated device.51 Thus, while many smartphones in the United States can already employ BeiDou as a GNSS, there is little security risk to U.S.-based users, as U.S. law does not allow the Chinese ground stations, which are required to track BeiDou users, to be installed in U.S. territory.52 The traditional one-way listening activity of receiving PNT is inherently safe from a cyber-intrusion standpoint.

Demand for increased location accuracy—already a driving requirement—spurs innovation and competition in GNSS design. Measurements of accuracy depend heavily on the application and methodology. When solely relying on a real-time fix from orbiting satellites, all four GNSS have roughly comparable performance, given that GLONASS is closing the performance gap.53 However, adding terrestrial antennas and signal post-processing, features that BeiDou is offering right now, promises orders of magnitude enhanced location accuracy that the physics of atmospherics and space flight prevent, thus enabling applications such as self-driving cars that the public yearns for.54 The new capabilities will differentiate the next generation of GNSS.


The fielding of modern precision-guided munitions is the most obvious military implication of BeiDou, though China has had guided munitions with that capability for a long time—first through GPS and later through a diplomatic agreement with Russia. The completion of BeiDou does have some potentially positive aspects for the United States and other global competitors. BeiDou will provide redundancy for both civilian and military applications worldwide; most commercial technology now incorporates multiple GNSS to take advantage of that redundancy. This redundancy can have powerful advantages, like being able to receive more satellite signals while in an urban canyon or, while in open spaces, getting more accurate positional data by using multiple GNSS. Militaries and governments worldwide can use BeiDou for redundancy as well. For example, American U-2 Dragon Lady pilots have been authorized to use multi-GNSS as a backup navigation system in case the aircraft’s GPS fails.55 Other U.S. military units could easily take advantage of BeiDou by incorporating similar commercial technologies into their toolkits. The United States should consider allowing the military to use multi-GNSS receivers produced by a trusted manufacturer.

Continued and diversified investment in space by other countries, especially peers and near-peers, reduces the strategic advantage of “nuking space,” whether literally or figuratively. Whereas in times past the overwhelming superiority and number of U.S. space-based platforms made the space domain itself a ripe target in a hot war, worldwide dependence on space, as well as the cost of repopulating constellations, acts as an incentive to preserve space as a global common.

Early on, the United States enjoyed a virtually unchallenged upper hand, as GPS was the gold standard of GNSS; this predominance made other nations dependent on the United States. That this reliance created tension in international relations is evident through the existence of now-multiple allied and adversary GNSS. When only GPS and GLONASS were available, countries worried about their reliance on just one or two systems. Now a solid quorum of GNSS gives all countries, both those with and without their own systems, a higher degree of confidence that they can plan on at least one system being available if another goes down.

Competition breeds innovation, though, and, even before BeiDou, GPS competed with both GLONASS and Galileo in a market that required constant improvements. That said, BeiDou may have applied new pressure. The newest GPS satellites (GPS III, which launched in 2018) will have three times better accuracy, up to eight times improved anti-jamming capabilities, and a longer lasting spacecraft.56 With several global systems currently online, it behooves the U.S. militarily to ensure that GPS remains the GNSS of choice. One addition in GPS III is a new signal that will “make it the first GPS satellite broadcasting a compatible signal with other international GNSS, like Galileo, improving connectivity for civilian users.”57 Of course, innovation requires fresh capital. The U.S. military was projected to spend $1.8 billion in fiscal year 2020 for GPS III, a figure that will likely increase as the United States contends with other GNSS.58 The United States should focus on building the most reliable, accurate, and trusted source of PNT. Copying BeiDou’s two-way communication method of delivering improved positioning accuracy at the cost of revealing user location and costly linear scalability is not a winning strategy in an expanding GNSS marketplace.

As worldwide reliance on GNSS expands, the criticality of these systems to multiple facets of modern life will continue to evolve; as a result, questions of sovereignty will loom as this critical infrastructure will hang, exposed, in the global commons of inner space. Tellingly, it was “desire for political sovereignty and control over a critical infrastructure” that sustained Galileo through years of strained planning and development. The United States should expect more nations to realize that depending on another’s GNSS makes a country exactly that—dependent. 59 If China had decided to forgo pursuing a GNSS when the United States, EU, and Russian Federation had pursued theirs, such avoidance could have been interpreted as a sign of weakness or inferiority, especially in such a high “face culture.” After all, China considered the exposure of its dependence on GPS to be an “unforgettable humiliation.”60 Because an emphasis on public image and a long societal memory are major aspects of Chinese culture, the United States should expect that China will attempt to never repeat this error.


Examining other GNSS programs offers some unique insights into what the United States should expect with BeiDou. Comparing BeiDou with GLONASS and Galileo reveals that, although the Chinese system will not cause a technological sea change in the GNSS ecosystem, BeiDou is significant and deserves attention, since it brings both security concerns and benefits to the United States. Through the lens of Great Power competition, BeiDou signifies another incremental erosion of the status of the United States as the sole superpower. China now offers sympathetic nations a viable GNSS alternative to GPS with highly competitive features that essentially did not exist before. Globally, GPS has been the de facto choice for PNT services because GLONASS was a markedly inferior service, and Galileo is only now coming into its own. BeiDou changes this status quo—it is clearly a better alternative than Galileo and GLONASS.

Despite GLONASS’s rocky start, Russia was eventually successful in fielding its system and garnering international cooperation and use of its GNSS, including sharing GLONASS-enabled precision-guided munitions. Still, while Russia broke GPS’s monopoly, it did not represent a fundamental shift in the status quo, neither was it an adequate replacement for GPS technologically. China has enormous economic, technological, and political advantages over Russia to speed the adoption of BeiDou as an (if not the) international standard of GNSS.

Galileo, set to reach FOC soon, may be aptly described as a demilitarized GPS without the political liability of single-country ownership. Galileo was quickly adopted by industry, and with multi-GNSS receivers already common, inclusion of BeiDou in most devices practically ensures that BeiDou will become the industry standard. It is, however, unlikely that BeiDou will displace GPS as the GNSS of choice for either military or civilian functions worldwide—BeiDou will likely become just another tool in the kit for most applications.

BeiDou does not pose a security threat for American users because the United States will not allow BeiDou ground stations in its territory; however, for nations participating in China’s BRI and taking advantage of the additional capability that ground stations offer, security is a concern. These nations are sacrificing privacy for access to superior service. Geopolitically, China has already sold access to its military-only signal to Pakistan and Saudi Arabia, allowing these countries to use BeiDou-enabled precision-guided munitions, which need not rely on other foreign GNSS, thus complicating any U.S. effort to deny these nations military-grade PNT capabilities directly through GPS.

BeiDou brings some benefits to the United States and the global community. Multi-GNSS receivers provide redundancy, additional features, and better positional accuracy, and BeiDou only deepens these advantages. Chinese investment in BeiDou also reduces the risk of conflict in the space domain, since physical destruction of any satellites puts other satellites in that orbit at risk, making kinetic conflict in space a shakier proposition. Finally, BeiDou forces all systems to innovate or risk becoming obsolete. The United States should take advantage of the benefits BeiDou provides while maintaining a vigilant eye on the security threats and implications that it brings. With the prestigious work of pioneering GPS complete, many other countries now join the United States in space, vying for dominance in navigation. The Nation would benefit from continued technological advances in GPS to keep it the gold standard of GNSS in this increasingly competitive field.
