According to the RIN website India’s Satellite Based Augmentation System has become the fourth such system to offer improved navigation.

On 30th December, the Indian Directorate General of Civil Aviation (DGCA) provisionally certified the country’s Satellite Based Augmentation System (SBAS) programme, the GPS Aided Geo Augmented Navigation (GAGAN) system, to the ‘Required Navigation Performance, 0.1 Nautical Mile’ (RNP0.1) service level. This will enable SBAS-capable aircraft to use GAGAN signals in space for en-route navigation and non-precision approaches – those without vertical guidance – in Indian air space.

GAGAN will bridge the gap between the EU’s EGNOS and Japan’s MSAS coverage areas, offering a huge area of seamless navigation to the aviation industry.
