Introduction:
The GPS-aided GEO augmented navigation (GAGAN) is an initiative by the Government of India to implement a regional satellite-based augmentation system (SBAS). It is designed to improve the accuracy, integrity, and availability of the Global Navigation Satellite System (GNSS) signals in India and the surrounding regions.
Explanation:
1. The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India.
- This statement is correct. GAGAN is indeed a regional SBAS implemented by the Government of India.
- SBAS is a system that utilizes additional ground-based and space-based infrastructure to augment the signals from GNSS satellites such as GPS, GLONASS, and Galileo. It provides improved accuracy, availability, and integrity of these signals for various applications including aviation, maritime, surveying, mapping, and transportation.
2. It is a system to improve the accuracy of a GNSS receiver by providing reference signals.
- This statement is correct. GAGAN aims to enhance the accuracy of GNSS receivers by providing reference signals.
- GAGAN consists of a network of ground-based reference stations, a master control center, and a geostationary satellite known as GSAT-8. These components work together to receive signals from GNSS satellites, monitor their accuracy, and generate correction messages.
- These correction messages, along with other navigation data, are then transmitted to the geostationary satellite, which broadcasts them to users within the coverage area.
- GNSS receivers equipped with GAGAN-compatible technology can receive these correction messages and apply them to improve the accuracy of their navigation solutions.
Conclusion:
Both the statements given in the question are correct. GAGAN is an implementation of a regional SBAS by the Government of India, and it aims to improve the accuracy of GNSS receivers by providing reference signals. GAGAN plays a crucial role in enhancing the reliability and precision of satellite navigation systems in India and the neighboring regions.
With reference to the GAGAN, consider the following statements:1. The ...
The Government of India has exempted Boeing 787 aircraft in India from complying with the indigenously developed GAGAN navigation system until December 2025 as the aircraft manufacturer has said that it involves a major design change.
- The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India.
- GAGAN helps aircraft with guided landing at airports that do not have an instrument landing system.
- It is a system to improve the accuracy of a GNSS receiver by providing reference signals.
Hence both statements are correct.
