With reference to the Indian Regional Navigation Satellite System (IRNSS), consider the following statements :
Which of the statements given above is/are correct ?
The IRNSS is being developed parallel to the GAGAN (GPS Aided GEO Augmented Satellite Navigation) program, the ISRO SBAS (Satellite Based Augmentation System) version of an overlay system for GNSS signal corrections.
The IRNSS system consists of a constellation of seven satellites and a supporting ground segment. Three of the satellites in the constellation will be placed in a geostationary orbit and the remaining four in a geosynchronous inclined orbit of 29º relative to the equatorial plane.
Such an arrangement would mean all seven satellites would have continuous radio visibility with Indian control stations. It will cover the entire country and an area extending about 1,500 sq. km beyond its border, with a position accuracy better than 20 m in all weather conditions.
The correct option is A.
