Can India, a country that may be considered a competitor to us in the future, really compete with the mainland's Beidou and even the GPS of the United States? When we turn our eyes to India and analyze their homegrown Navik system, we find that the truth is not as simple as we think.
India has indeed managed to make its own satellites, and their satellite navigation system Navik is already operating in their country, even in their neighboring countries. But can we compare their system directly to global navigation systems, such as GPS in the United States or Beidou in China?
Continental's Beidou system began construction in 1994, and after more than 20 years of efforts, Beidou system has developed into a satellite navigation system on a global scale. The strength of the Beidou system is strong, and even data shows that in the second year of Beidou satellite's official use, its total service output value reached 470 billion yuan. However, India's choice is obviously based on national security and national independent research and development considerations.
Let's take a look at the Navik system in India. The construction of the Navik system dates back to 2007, when the Indian Space Research Organization began developing a satellite navigation system. However, it was not until 2016 that India completed the launch of seven satellites and realized the initial networking of the satellite navigation system.
At the same time, I think there needs to be reservations about the claim that performance is comparable to GPS and Beidou. Although the Navik system has completed the initial networking, it has obvious gaps with Beidou in positioning and communication capabilities. For example, Navik's timing accuracy is 50 nanoseconds, while Beidou's is 20 nanoseconds. The spatial error of Navik is 20m, while the positioning accuracy of Beidou is more than 4.4m.
Whether it can be compared with global GPS is also controversial. Globally, the GPS system is supported by more than 30 satellites to achieve full coverage worldwide. However, the Navik system currently has only 7 satellites and can only be used as an area navigation system, and its coverage is not comparable to GPS.
In fact, India already has a certain accumulation in satellite technology. They have a layout in the fields of communication satellites and remote sensing satellites, and they also have certain strength. However, India still faces great challenges in building a full-fledged satellite navigation system with global coverage.
The first is the number and coverage of satellites. At present, India's Navik system has only 7 satellites and can only achieve regional coverage. Moreover, the number and quality of satellites directly determine the accuracy and stability of the navigation system. India still has a lot of room for improvement in this regard.
The development of satellite navigation systems did not happen overnight. In addition to the design, launch and operation of satellites, it also includes the construction of ground base stations, signal processing and optimization of positioning algorithms. This requires a lot of capital investment and time accumulation. At this level, India is still a long way from becoming a member of the global satellite navigation system.
The international layout of satellite navigation systems is also an important issue. At present, Beidou has been used in 137 countries, while India's Navik is still in the stage of regionalization. Although India has great market potential, it needs to solve a series of technical and policy problems in order to promote further.
Of course, for India, their decision to develop their own satellite navigation system is itself a national development strategy. This is not only to meet the needs of the domestic market, but also to improve the country's scientific and technological level. Despite the challenges, it is also the source of motivation for their continuous improvement.
Going back to the original question, the refusal to use a question like China's Beidou is actually impossible to answer simply. India's Navik system, although it has its advantages in some aspects, still has a big gap compared to GPS and Beidou in many key areas such as global layout, system accuracy and stability.
This does not mean that India's satellite navigation system is not promising. Each country has its own rhythm and path on the road of scientific and technological development. India has its own advantages and potential, as long as they continue to invest in research and development and strengthen technology accumulation, it is possible to catch up with or even surpass existing satellite navigation systems in the future.
The comparison of satellite navigation systems is not only a technical comparison, but also a reflection of national strategy and international competition. We should treat the scientific and technological development of each country with an open attitude, and at the same time, we should remain vigilant and constantly improve our scientific and technological strength to meet the challenges that may arise in the future.
