Indian Space Research Organization successfully launched IRNSS-1D into orbit today using its own rocket.

The 1,425 Kg satellite was launched at 5:19 pm with the help of 44 meters tall, 320 tones heavy Polar Satellite Launch Vehicle – (PSLV-C27).

The success of IRNSS has brought India very close to joining the group of very few nations with their own navigational satellite system.

The navigational system will give a strong boost to India’s defence capabilities. It will also help the country in mineral exploration and navigation.

IRNSS is similar to (GPS) of the US (24 satellites), Glonass of Russia (24 satellites) and Galileo of Europe (27 satellites), China’s Beidou (35 satellites).

Launched from the second launch pad at the Satish Dhawan Space Centre, the satellite is controlled by the Mission Control Facility (MCF) at Hassan in Karnataka.

The President of India,  Pranab Mukherjee also congratulated the Indian Space Research Organization (ISRO) for the successful launch of PSLV-C27.

In a message to  AS Kiran Kumar, Chairman of ISRO, the President said, “My heartiest congratulations to you and your entire team at the Indian Space Research Organisation (ISRO) for the successful launch of PSLV-C27, carrying the IRNSS-1D. I am very happy to know that this is the fourth in the series of seven satellites of the Indian Regional Navigation Satellite System. I understand the IRNSS-1D will provide navigation, tracking and mapping services which will take us closer to setting up our own navigation system. ”

The nation is proud of this achievement which has demonstrated, yet again, India’s increasing space capabilities, President added.

India’s 40th communication satellite GSAT-31 was successfully put into orbit by an Ariane 5 rocket belonging to Arianespace on early Wednesday, said Indian space agency ISRO and Arianespace.

According to Indian Space Research Organisation (ISRO), the telecommunication satellite, GSAT-31 was successfully launched on February 06, 2019 from Kourou launch base, French Guiana by Ariane-5.

The 2,535-kg GSAT-31 would augment the Ku-band transponder capacity in geostationary orbit.

According to ISRO, GSAT-31, with a mission life of 15 years, will be used for supporting VSAT networks, television uplinks, digital satellite news gathering, DTH television services, cellular back haul connectivity and more.

The GSAT-31 will provide continuity to operational services on some of the in-orbit satellites, ISRO said.

The two Ku-band beacon downlink signals are transmitted by the satellite for ground tracking purpose, it said.

According to Arianespace, it opened its 2019 mission activity by successfully orbiting a pair of telecommunications spacecraft – Saudi Geostationary Satellite 1/Hellas Sat 4 (HS-4/SGS-1) and GSAT-31 with Ariane 5 rocket.

Arianespace CEO Stéphane IsraAl confirmed the success in post-launch comments from the spaceport’s control room. “For the first Ariane 5 launch of the year, our heavyweight vehicle has once more performed flawlessly,” he was quoted as saying in a statement.

IsraAl said that GSAT-31 was the 23rd ISRO satellite orbited by Arianespace and Ariane-series launchers, tracing the relationship back to India’s APPLE small experimental communications spacecraft, lofted in 1981 by an Ariane 1 version.

He added: “Arianespace is honoured ISRO has entrusted Ariane 5 for two launches back-to-back, with the last Ariane 5 of 2018 launching GSAT-11, and today the first one of the year 2019, which orbited GSAT-31!”
