IRNSS

Statement 2 is incorrect: It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. An Extended Service Area lies between primary service area and area enclosed by the rectangle from Latitude 30 deg South to 50 deg North, Longitude 30 deg East to 130 deg East.

Statement 3 is incorrect: While India has been working on enhancing the coverage of its navigation system, as of the given timeframe (2019), it does not have full global coverage. The system is primarily regional, although there are plans for augmentation and expansion.
