IRNSS-1I is a replacement satellite for India's home-grown navigation constellation IRNSS. The satellite joins seven other satellites in the Indian Regional Navigation Satellite System, also known as NavIC, which stands for Navigation with Indian Constellation. IRNSS 1I was placed into an on-target orbit ranging between 174 miles (281 kilometers) and 12,881 miles (20,730 kilometers) above Earth. The navigation satellite is scheduled to enter service in May, after four orbit-raising burns with the satellite's main engine to climb into a circular geosynchronous-type orbit at an altitude of more than 22,000 miles [35,406 km]. The craft's operating orbit will be tilted at an angle of 29 degrees to the equator and centered at 55 degrees east longitude, requiring a plane change from the 19.2-degree inclination targeted on initial launch.
