Akhilesh calls Modi's tour during Ramzan 'international appeasement' of Muslims

New Delhi, Jul 25: The Indian Air Force (IAF) has made key appointments in its different commands all across the country including formations that look after operations along the borders with China and Pakistan.

Air Marshal Vivek Ram Chaudhari has been appointed as the head of the Delhi-based Western Air Command (WAC) which looks after both the crucial borders, with China in Ladakh and all along Pakistan from Ladakh up to Bikaner in Rajasthan.

Chaudhari would be assuming charge of the new office on August 1, replacing Air Marshal B Suresh who is superannuating after a brief tenure of nine months there.

In the Shillong-based Eastern Command, incumbent Air Marshal RD Mathur would be moving to the Bangalore-based Training Command on October 1, he will be replaced by Air Marshal Amit Dev. The Eastern Command looks after the entire Northeastern region including the border with China from Sikkim to Arunachal Pradesh.

As per the new appointments issued on July 24, Kargil war gallantry awardee Air Marshal Dilip Kumar Patnaik would be taking over as the Senior Air Staff Officer (SASO) at the Prayagraj-based Central Air Command.

On October 1, the Air Force would also get a new in-charge of personnel in Air Marshal RJ Duckworth who is presently the SASO in the WAC.

Air Marshal Vikram Singh would be the next SASO of the WAC. Air Marshal J Chalapati-- the officer who had briefed the Supreme Court on the Rafale issue last year, would be the SASO of the Trivandrum-based Southern Air Command.

Jan 17: India's "high power" communication satellite GSAT-30 was successfully launched in the early hours of January 17, the Indian Space Research Organisation (ISRO) said.

The satellite, aimed at providing high-quality television, telecommunications and broadcasting services, was launched onboard Ariane 5 rocket from French Guiana.

Blasting off from the Ariane Launch Complex in Kourou, a French territory located in northeastern coast of South America at 2.35 am IST, European space consortium Arianespace's Ariane 5 vehicle injected GSAT-30 into the orbit in a flawless flight lasting about 38 minutes.

Arianespace CEO Stéphane Israël tweeted about the successful launch of GSAT-30.

ISRO's U R Rao Satellite Centre Director P Kunhikrishnan, who was present in Kourou, congratulated the ISRO community and Arianespace team on the successful launch.

Calling it an "excellent start" to 2020 for ISRO with the launch, he said, "The mission team at the master control facility have already acquired the satellite and they will immediately complete the post launch operations...."

The 3,357-kg satellite, which was deployed from the lower passenger position of Ariane-5 launch vehicle (VA 251) into to geostationary transfer orbit (GTO), is configured on ISRO's enhanced I-3K Bus structure to provide communication services from Geostationary orbit in C and Ku bands.

The satellite derives its heritage from ISRO's earlier INSAT/GSAT satellite series, and is equipped with 12 C and 12 Ku band transponders.

GSAT-30 is to serve as replacement to the "aging" INSAT-4A spacecraft services with enhanced coverage, ISRO has said, adding the satellite provides Indian mainland and islands coverage in Ku-band and extended coverage in C-band covering Gulf countries, a large number of Asian countries and Australia.

With a mission life of 15 years, GSAT-30 is an operational communication satellite for DTH, television uplink and VSAT services.

The Bengaluru-headquartered ISRO has said the communication payload of GSAT-30 is specifically designed and optimised to maximise the number of transponders on the spacecraft bus.

According to the space agency, the spacecraft would be extensively used for supporting VSAT (Very Small Aperture Terminal) network, television uplinking and teleport services, digital satellite news gathering (DSNG), DTH television services, cellular backhaul connectivity and many such applications.

One Ku-band beacon downlink signal is transmitted for ground-tracking purpose, it added.

For its initial flight of 2020, Arianespace on its website said, it would orbit EUTELSAT KONNECT, a telecommunication satellite for the operator Eutelsat, along with GSAT-30, using an Ariane 5 launch vehicle from the Guiana Space Centre.

EUTELSAT KONNECT – which was produced by Thales Alenia Space for Eutelsat – was riding in the upper position of Ariane 5's payload arrangement, and was released first in the flight sequence at 27 minutes following liftoff.

Since the launch of India's APPLE experimental satellite on Ariane Flight L03 in 1981, Arianespace has orbited 24 satellites, including GSAT-30, for the Indian space agency.
