ISRO launch it's fifth navigation satellite by PSLV-C31

ISRO's Polar Satellite Launch Vehicle, PSLV-C31, with success launched the 1425 kilo IRNSS-1E, the fifth satellite within the Indian Regional Navigation Satellite System (IRNSS) these days morning (January 20, 2016) from Satish Dhawan area Centre SHAR, Sriharikota. This can be the 32 consecutively triple-crown mission of PSLV and therefore the eleventh in its 'XL' configuration. (click here  For more space news)..

After the PSLV-C31 lift-off at 09:31 hrs (9:31 am) IST from the Second Launch Pad with the ignition of the primary stage, the following necessary flight events, namely, strap-on ignitions and separations, initial stage separation, second stage ignition, heat-shield separation, second stage separation, third stage ignition and separation, fourth stage ignition and satellite injection, happened as planned. Once a flight of regarding 18 minutes 43 seconds, IRNSS-1E Satellite was injected to associate elliptical orbit of 282.4 km X 20,655.3 metric linear unit inclined at associate angle of 19.21 degree to the equator (very near the supposed orbit) and with success separated from the PSLV fourth stage. once injection, the star panels of IRNSS-1E were deployed mechanically. ISRO's Master management Facility (at Hassan, Karnataka) took over the management of the satellite. within the coming back days, four orbit manoeuvres are going to be conducted from Master management Facility to position the satellite within the orbit at 111.75 deg East great circle with twenty 8.1 deg inclination.

IRNSS-1E is that the fifth of the 7 satellites constituting the house phase of the Indian Regional Navigation Satellite System. IRNSS-1A, 1B, 1C and ID, the primary four satellites of the constellation, were with success launched by PSLV on Gregorian calendar month 02, 2013, April 04, 2014, October 16, 2014 and March 28, 2015 severally. All the 4 satellites area unit functioning satisfactorily from their selected orbital positions.

IRNSS is associate freelance regional navigation satellite system designed to supply position data within the Indian region and 1500 metric linear unit round the Indian terra firma. IRNSS would supply 2 kinds of services, namely, customary Positioning Services (SPS) - provided to any or all users - and Restricted Services (RS), provided to authorised users.

A number of ground stations accountable for the generation and transmission of navigation parameters, satellite travel and watching, etc., are established in 18 locations across the country. within the coming back months, the remaining 2 satellites of this constellation, namely, IRNSS-1F and immune globulin, area unit scheduled  to be launched by PSLV, thereby finishing the whole IRNSS constellation.

ISRO's Reusable launch vehcle- Technology Demonstration program

ISRO

India plays leading roll in space research now the next mission in launching vehicle is taken by ISRO which  RLV. THhe world knows, ISRO make a heavy mission possible with low cost and less period of time. Now, the technological view of our scientist, improving the level of launching vehicle to make it reusable one.

This mission is like to maken a prototype launch on april 16 but which is postborne to coming year 2016.

RLV-TD
 

The cost of access to space is the major deterrent in space exploration and space utilization. A reusable launch vehicle is the unanimous solution to achieve low cost, reliable and on-demand space access.

Reusable Launch Vehicle-Technology Demonstration Program or RLV-TD is a series of technology demonstration missions that have been considered as a first step towards realizing a Two Stage To Orbit (TSTO) fully re-usable vehicle. A Winged Reusable Launch Vehicle technology Demonstrator (RLV-TD) has been configured to act as a flying test bed to evaluate various technologies, namely, hypersonic flight, autonomous landing, powered cruise flight and hypersonic flight using air-breathing propulsion.

These technologies will be developed in phases through a series of experimental flights. The first in the series of experimental flights is the hypersonic flight experiment (HEX) followed by the landing experiment (LEX), return flight experiment (REX) and scramjet propulsion experiment (SPEX). Reusable Launch Vehicle Technology Demonstrator Hypersonic Experiment (RLV-TD HEX1) wherein the hypersonic aero-thermo dynamic characterization of winged re-entry body along with autonomous mission management to land at a specified location and characterization of hot structures are planned to be demonstrated.
