Story of IRNSS
Why India needed IRNSS?
Though the Indian government had the ideology to have Navigation Satellite system of their own, the situation faced by the Indian military during the Kargil war, in 1999 spurred the Indian Government, even more, to make it possible as early as they could.
During the Kargil war, the US Government denied their GPS access to the Indian military in a hostile situation, which made the Indian government realize how the dependency over the foreign GNSS would put India’s interests under a vulnerable condition.
What is IRNSS?
The Indian Regional Navigation Satellite System (IRNSS) is India’s regional satellite navigation system that is designed by the Indian Space Research Organization (ISRO) to provide geospatial positioning information within the Indian sub-continent. India’s answer to GPS. It enables users to map out their locations. The objective of developing IRNSS was to cut down India’s dependence on foreign navigation satellite systems.
IRNSS is otherwise called as NavIC – Navigation with Indian Constellation.
Initialization of IRNSS and its Launch
The Indian government approved the project in May 2006. In the year 2010, it was reported that India was planning to start to launch their satellites by the end of 2011, which though got postponed and the First IRNSS satellite was launched on 1st July 2013. And the last satellite was launched on 12th April 2018. There are 8 satellites in the geostationary orbit and which covers up to 1500kms from the boundaries of India.
What does IRNSS provide?
This independent Indian Satellite based positioning system for critical National applications’ main objective is to provide Reliable Position,
Navigation, and Timing services over India and its neighborhood, to provide fairly good accuracy to the user.
The IRNSS will provide two types of services
- Standard Positioning Service (SPS)
- Restricted Service (RS)
Standard Positioning Service (SPS) is released to the public to provide the essential information on the IRNSS signal-in-space, to facilitate research & development and aid the commercial use of the IRNSS signals for navigation-based applications.
Restricted Service (RS) is an encrypted service provided only to authorized users.
The IRNSS is expected to provide a position accuracy of better than 20 m in the primary service area.
Some applications of IRNSS are:
- Terrestrial, Aerial and Marine Navigation
- Disaster Management
- Vehicle tracking and fleet management
- Integration with mobile phones
- Precise Timing
- Mapping and Geodetic data capture
- Terrestrial navigation aid for hikers and travelers
- Visual and voice navigation for drivers
AIS – 140
Automotive Industry Standard shortened as AIS 140, is a set of norms published by ARAI (Automotive Research Association of India) which is designed explicitly to obtain complete authority over public transportation to make travel/transportation hassle-free and it deals with the necessary safety features required on government and commercial transport. It must also contain one or more panic/SOS buzzers depending on the length of the vehicle.
AIS 140 is designed to obtain a real-time position using the Global Navigation Satellite System (GNSS), IRNSS and it can fetch the transportations’ performance information.
India’s IRNSS uses the L5 band which is the latest, whereas the US’s GPS and Russia’s GLONASS uses the L1 band.
