ISRO to Launch Last IRNSS Spacecraft
The Indian Space Research Organization (ISRO) has announced plans to launch the final satellite for the Indian Regional Navigation Satellite System (IRNSS) on April 28.
The IRNSS-1G launch is scheduled for 12:50 p.m. local time from Satish Dhawan Space Center, in Sriharikota, Andhra Pradesh, India, with the navigation payload being carried into space on India’s Polar Satellite Launch Vehicle (PSLV-C33).
Seven satellites comprise the IRNSS constellation. Three satellites are located in geostationary orbits (GEOs), including IRNSS-1G, at 32.5° East, 83° East, and 131.5° East longitude, and the remainder located in geosynchronous orbits (GSOs) with the required inclination and equatorial crossings of two GSOs each at 55° East and two at 111.75° East.
