    Isro's next PSLV to carry indigenous navigation satellite

    After successful launch of six Singapore satellites recently, Indian space scientists will launch PSLV rocket carrying the country’s indigenous IRNSS-1E navigation satellite from the spaceport of Sriharikota on January 20.

    Indian Space Research Organisation (Isro) said the Mission Readiness Review Committee (MRRC) meeting was held on Sunday and decided the countdown activities of the rocket. “MRCC meeting was held today. The countdown is expected to start at 9:30 am on Monday,” Isro’s spokesperson Devi Prasad Karnik told Deccan Herald on Sunday.

    Stating that the rocket was moved from vehicle assembly building to the second launch pad, the official pointed out that this is the first satellite launch for Isro in 2016.

    According to him, as in the previous four launches of Indian Regional Navigation Satellite System (IRNSS) satellites, PSLV-C31 will use “XL” version of PSLV. The 44.4 metre tall PSLV-C31, Isro’s most trusted rocket and workhorse launch flight, weighing 320 tonne, will carry IRNSS-1E, from the Satish Dhawan Space Centre (SDSC).

    The satellite, which is the fifth navigation device of the seven of its kind constituting the IRNSS space segment, is designed to provide accurate position information service to users in India as well as the region extending up to 1,500 km from its boundary.

    IRNSS-1E carries two types of payloads – navigation payload and ranging payload. The latest IRNSS, which will provide Standard Positioning Service (SPS), is responsible for navigation parameter generation and transmission, satellite control, ranging and integrity monitoring as well as time keeping.

    The year’s first domestic space mission will take off on Wednesday morning

    The year’s first domestic space mission will take off on the morning of Wednesday, January 20, at Sriharikota with the fifth regional navigation spacecraft, the IRNSS-1E.

    At the Satish Dhawan Space Centre, the launch team began a 48-hour countdown for the flight of the satellite launch vehicle, PSLV-C31, at 9.31 a.m. on Monday. The flight was cleared by two high-level review committees on Sunday, according to the Indian Space Research Organisation.

    IRNSS-1E is a 1,425-kg spacecraft carrying navigation and ranging payloads. It is similar to the earlier four navigation satellites IRNSS-1A to 1D which were put in orbit between July 2013 and March 2015.

    Two more navigation spacecraft – IRNSS-1F and 1G – are due to follow in February and March, an ISRO official said. They will then complete the seven-satellite constellation, otherwise called the ‘Indian GPS’.

    The full fleet is likely to be switched on for regular use by end-2016 after it is tested and tried for a few months.

    Already, the first four navigation spacecraft have been giving 18-hour positional information with good accuracy of the Indian region; the duration will improve with new satellites, the official said.

    After a series of orbit corrections post-launch, IRNSS-1E will be placed in a geosynchronous orbit over 111.75 degrees east longitude. It will go around Earth at a distance of 20,000 km and inclined at 28.1 degrees.

    For the current mission, ISRO is using the XL (extended) version in the first stage of the four-stage PSLV rocket. This format is being used for the 11th time.
