Isro is not stopping and is in continuous advancement leaps.

The nation's seventh navigation satellite scheduled for Thursday is scheduled on time, the Indian Space Research Organisation (Isro) stated on Wednesday, 27th April 2016.

As per Isro, the succeeding position for the launch of 44.4 metre, 320 tonne Polar Satellite Launch Vehicle (PSLV) carrying Indian Regional Navigation Satellite System-IRNSS-1G is expected to take place at at 12:50pm on Thursday, the 28th April 2016.

The rocket is expected to put the 1,425-kg IRNSS-1G satellite into orbit the at an altitude of 497.8km, just after 20 minutes. The PSLV rocket is a four stage/engine rocket power-driven by solid and liquid fuel both- but alternatively.

The satellite has a design life span of 12 years and boasts of two payloads for navigation and ranging. The navigation payload of IRNSS-1G will send out navigation service signals to the users. This payload will be in service in L5-band and S-band. A highly precise rubidium atomic clock is part of the navigation payload of the satellite.


The ranging payload of IRNSS-1G consists of a C-band transponder (automatic receivers and transmitters of radio signals) which makes accurate purpose of the range of the satellite possible.

According to Isro the applications of IRNSS will be useful in terrestrial, aerial and marine navigation, vehicle tracking and fleet management, terrestrial navigation for hikers and travelers, disaster management, integration with mobile phones, mapping and geodetic data capture and visual and voice navigation for drivers and apart from these, the IRNSS will be useful in defense purposes as well.

India has already launched six regional navigational satellites (IRNSS-1A, 1B, 1C, ID,1E and 1F) as components of a constellation of seven satellites to provide exact location information service to users across the country and the region, which extends up to an area of 1,500 km. The full system comprises of nine satellites - seven in space and two on ground as stand-by.

The first satellite IRNSS-1A was launched in July 2013, the second IRNSS-1B in April 2014, the third on October 2014, the fourth in March 2015, and the fifth and sixth on January 20 and March 10, 2016.

Once this process is complete, India need not be dependent on other platforms for the accurate positioning system.

Isro needs all the applause and a big heartfelt thank you.
