Isro Completes Fourth Orbit-Raising Manoeuvre Of GSAT-7A

Indian Space Research Organisation (ISRO) has completed the fourth manoeuvre to position the GSAT-7A military communication satellite closer to its final position. The satellite is currently between 35,800 and 36,092 kilometres from earth and is very close to its final position in the geostationary orbit, which is located at an altitude of around 35,786 km from Earth.

Now the satellite will be moved in a final orbital manoeuver to its final position. ISRO uses propulsion system, or thrusters to perform manoeuvres. ISRO has already done four such manoeuvres on GSAT-7A so far.


The features of the GSAT-7A are:

  • ISRO has built GSAT-7A for the Indian Air Force and was launched on a GSLV-Mk2.1 rocket (GSAT-F11) on 19 December from the Satish Dhawan Space Centre (SDSC) at Sriharikota.
  • The satellite will be placed in the sun-synchronous orbit, which is roughly 2000 kilometres higher than the geosynchronous transfer orbit, in which most satellites are released by launch vehicles to be moved and positioned in low-Earth orbit.
  • GSAT 7A is ISROs 35th communication satellite and it weighs 2.25 ton.
  • The satellite is designed to work in the Ku-band frequency and houses a powerful ‘I-2K’ bus, which functions as the satellite’s communication hub or service module.

Benefits to Air Force:

GSAT-7A will allow cross-connectivity between different ground radar stations, airbases and Airborne early warning and control (AWACS) aircraft like the Beriev A-50 Phalcon. It will also boost the air force’s network-dependent warfare capabilities, enhancing its abilities to operate globally.

In future, it is also expected that it would give a big push to drone operations in the Indian military by helping the Navy reduce its reliance on ground-based control stations and switch to satellite-controlled unmanned aerial vehicles (UAVs), that offer better range and endurance.

‘Made in India’ e-dumper put into trial by Coal India

Coal India for the first time, has started using an indigenously-made, 205-tonne electric dumper, a critical piece of equipment in mining. This indigenously-made dumper has been developed by state-owned BEML. Coal India has put this electric dumper on a trial in Northern Coalfields’ Amlohri coal mine. This indigenously-made dumper is the biggest one deployed by Northern Coalfields limited.

This indigenously-made dumper is expected to increase competition among suppliers, bring down costs and improve the availability of spares.

How the successful trail can give a boost to Make in India?

The successful trial will open a plethora of opportunities because

  • The successful trial will enable BEML to participate in tenders for higher capacity dumpers floated by Coal India.
  • Northern Coalfields limited has already floated one such tender and the Eastern Coalfield limited is in the process of floating tender for 10 dumpers.
  • The dumper market in India is captured by Russia’s Belaz, Tata Hitachi and Caterpillar. But these dumpers come at prices upwards of Rs 15 crore.

If the BEML gains an opportunity to enter the e-dumper market, it will act as a disruptor in the market and give fierce competition to the big market players. It can open a plethora of opportunities for BEML and give a fillip to Make in India together with cutting the costs for Coal India.

Make in India

‘Make in India’ campaign aims to facilitate investment, foster innovation, enhance skill development, protect intellectual property & build best in class manufacturing infrastructure in India.  The initiative aims to transform India into a global manufacturing hub. The initiative focuses on creating jobs in 25 sectors.
