Policy Ignition: India’s satellite navigation sector is on the path of greater development.

BANGALORE: India’s satellite-based navigation and augmentation services sector is on track to grow with the proposed policy towards efficient development, operation and maintenance of such systems.
The Department of Space (DOS) intends to formulate a “comprehensive and basic” national policy for satellite-based navigation – Indian Satellite Navigation Policy – 2021 (SATNAV Policy – 2021)
The draft has now been placed on the Indian Space Research Organization’s (ISRO) website for public consultation, after which it will be placed before the Union Cabinet for final approval.
It seeks to achieve self-reliance in “satellite-based navigation and enhancement services with an emphasis on ensuring availability and quality, increasing utilization, working towards progressive evolution of services and promoting research and development.” Is”.
In the last few decades, there has been a tremendous increase in the number of applications that position, speed and Time. (PVT) services are provided by a space-based navigation system.
With the advent of information and mobile phone technology, millions of consumers across India rely heavily on PVT-based applications in all walks of life.
The Global Navigation Satellite System (GNSS) is a space-based navigation system that provides navigation signals around the world.
Currently, there are four GNSS-GPS from the United States. Glonas from Russia Galileo from the EU and Baidu from China – offer global PVT solutions.
In addition, there are two regional navigation satellite systems – Nuke of India and QZSS offering navigation signals from Japan.
Navigation signals for a variety of applications ranging from aerial, aerospace, marine and ground applications to tracking, telematics, location based services (cell phones and mobile devices), automotive, surveys, mapping and GIS. Are offered. Timing
GNSS also offers secure navigation signals specifically for strategic applications in its respective countries as free-to-air signals are sensitive to adversaries.
According to the draft, such secure services are also needed, especially for the Indian strategic community.
That is why the Government of India has set up a flexible and independent system – Navigation with Indian Constellation (NavIC) which is completely under its control.
Satellite-based augmentation systems (SBAS) are enhancing navigation satellite towers by providing integrity and corrective information through geostationary satellites.
WAAS of USA, EGNOS of EU, SDCM of Russia, SNAS / BDSSBAS of China offer these services in their default coverage area.
The Government of India has also set up a similar SBAS system – GPS Aided Geo-Augmented Navigation – (GAGN) for Indian airspace.
“The space-based navigation / enhancement system is essentially a public good that should be accessible to all users,” the DOS said.
“Only the government can provide such national infrastructure.”
Furthermore, in order to strengthen the Government’s ‘Spiritual India’ initiative, it is important to ensure the continuity of Nivek and Gagan services, upgrade the system in view of technological advances and work closely with other GNSS / SBAS. Capacity must be maintained. .
Therefore, it is appropriate to formulate a comprehensive and solid national policy for satellite-based navigation.
The policy aims to ensure the safe and continuous availability of free-to-air navigation signals for civilian use and to ensure safe navigation signals for strategic use in the default coverage area.
Another goal is to ensure the guarantee and continued availability of SBAS to ensure aviation safety in the coverage area.
There is also a need to work towards the progressive evolution of navigation signals and the expansion of coverage for better use.
Attention will also be paid to the development of technology to enhance the navigation satellite system, and to enhance the compatibility and collaboration of Indian satellite navigation with other GNSS / SBAS signals.
Another goal is to promote Indian industry and educational institutions to carry out research and development activities in the field of satellite navigation-based applications with an emphasis on social benefits.
The DOS said in the draft that work also needs to be done to facilitate global use of Indian satellite navigation and enhancement systems.
