Promoting Beidou Development Subsidies: A Leap in Global Navigation Systems

China’s Beidou satellite navigation system is poised for substantial growth with the introduction of development subsidies. This initiative will enhance Beidou’s capabilities, making it a strong competitor in the global navigation market. The Indian Regional Navigation Satellite System (IRNSS) is also making strides, e plans to launch seven satellites to reduce dependence on the US-controlled GPS. This article delves into the specifics of these advancements, their implications, and the future of global navigation systems.


The Beidou Satellite Navigation System

Background and Development

The Beidou satellite navigation system, also known as BDS, is China’s answer to the US Global Positioning System (GPS) and Russia’s GLONASS. The system’s development follows a three-step strategy:

  1. Experimental Phase (2000): The initial phase saw the launch of the Beidou-1 system, making China one of the first countries to develop an independent satellite navigation system.
  2. Regional Coverage (2012): The second phase involved the deployment of the Beidou-2 system, providing services across the Asia-Pacific region.
  3. Global Reach (2020): The final phase aims to establish a global navigation system with the Beidou-3 constellation, which was completed in 2020.

Current Status and Future Plans

As of 2023, the Beidou system comprises 35 satellites, offering global coverage and a range of services, including positioning, navigation, and timing (PNT). The newly introduced subsidies are expected to further enhance these capabilities, focusing on improving accuracy, reliability, and the development of new applications.

Indian Regional Navigation Satellite System (IRNSS)


India’s Indian Regional Navigation Satellite System (IRNSS), also known as NavIC (Navigation with Indian Constellation), is designed to reduce the country’s dependence on the US-controlled GPS. The system consists of seven satellites, providing accurate position information to users in India and the surrounding region.

Launch and Deployment

According to the Indian Space Research Organization (ISRO), the IRNSS constellation includes three geostationary satellites and four geosynchronous satellites. These satellites are positioned at an altitude of approximately 36,000 kilometers, covering India and extending up to 1,500 kilometers beyond its borders.
