Isro Begins Countdown for Fifth Navigation Satellite Launch on Wednesday

The 48-hour commencement for the lift of an Indian rocket - the first for 2016 - with the nation's fifth route satellite as the sole traveler started at 9.31am on Monday, senior Isro authorities said.

"The 48-hour commencement for the dispatch of rocket Polar Satellite Launch Vehicle (PSLV-31) conveying Indian Regional Navigation Satellite System-IRNSS-1E started in the Sriharikota rocket port in Andhra Pradesh," senior authority at Indian Space Research Organization (ISRO) told IANS.

The rocket is required to take off at 9.31 a.m. on January 20 to put into space the 1,425 kg IRNSS-1E satellite.

Till date India has dispatched four provincial navigational satellites (IRNSS-1A, 1B, 1C and ID) as a component of a group of stars of seven satellites to give exact position data administration to clients the nation over and the district, stretching out up to a territory of 1,500km.

In spite of the fact that the full framework contains nine satellites - seven in circle and two on the ground as stand-by - the route administrations could be made operational with four satellites, Isro authorities had said before.

Every satellite expenses around Rs. 150 crores and the PSLV-XL adaptation rocket costs around Rs. 130 crores. The seven rockets would include a cost of around Rs. 910 crores.

The whole IRNSS group of stars of seven satellites is wanted to be finished in 2016 itself.

The primary satellite IRNSS-1A was dispatched in July 2013, the second IRNSS-1B in April 2014, the third on October 2014 and the fourth on March 2015.

Once the local route framework is set up, India need not be subject to different stages.

By, IRNSS-1E conveys two sorts of payloads - route and running payloads.

The route payload of IRNSS-1E will transmit route administration signs to the clients. This payload will be working in L5-band and S-band.

An exceptionally precise Rubidium nuclear clock is a piece of the route payload of the satellite.

The running payload of IRNSS-1E comprises of a C-band transponder (programmed beneficiaries and transmitters of radio signs) which encourages precise determination of the scope of the satellite.

IRNSS-1E likewise conveys Corner Cube Retro Reflectors for laser running.

On January 20 at 9.31 a.m. the PSLV-XL rendition rocket standing 44.4 meters tall and weighing 320 ton would take off from India's rocket port at Sriharikota.

A little more than 19 minutes into the flight the rocket would put into space IRNSS-1E at a height 503.3 km.

The satellite's life range is 12 years, the Isro official said.

The Indian space organization's central goal status survey council (MRRC) and the dispatch authorisation board (LAB) on Sunday gave the green sign for the Wednesday's rocket dispatch.
