The successful GSAT-31 launch on February 6, 2019, from the Spaceport in French Guiana marked a significant stride in India’s quest for robust and reliable satellite communication. This India communication satellite, engineered by the Indian Space Research Organisation (ISRO), is poised to revolutionize digital connectivity across the nation, from bustling urban centers to remote island territories.
GSAT-31 Launch Details and Specifications
Lifted into space by the powerful Ariane 5 VA-247 launch vehicle, the GSAT-31 satellite, weighing 2536 kg, was placed into an elliptical Geosynchronous Transfer Orbit. This crucial step initiated a series of orbit-raising maneuvers, eventually positioning the satellite in its final geostationary orbit, approximately 36,000 km above the equator. The ISRO satellite launch was precisely timed, with the separation of the satellite from the Ariane 5 upper stage occurring 42 minutes into the flight.
GSAT-31 is configured on ISRO’s enhanced I-2K Bus, maximizing the capabilities of this platform. Equipped with Ku-band transponders and a wide-beam transponder, it offers flexible frequency segments and extensive coverage. This space technology will support a wide range of applications, including VSAT networks, television uplinks, digital satellite news gathering (DSNG), DTH television services, cellular backhaul connectivity, 1 stock exchange operations, and e-governance initiatives.
The Role of GSAT-31 in India’s Communication Infrastructure
The importance of the GSAT-31 launch extends far beyond technical specifications. It addresses the growing need for reliable digital connectivity in India, a nation with a vast and diverse geography. This satellite will play a vital role in bridging the digital divide, ensuring that even the most remote areas have access to essential communication services.
Consider the impact on rural communities. GSAT-31 will enable improved access to education, healthcare, and government services through telecommunication services. For disaster management, the satellite will provide crucial communication links during emergencies, ensuring timely information dissemination and coordinated relief efforts. In the realm of entertainment, it will enhance the quality and reach of DTH television services.
Technical Aspects of the GSAT-31 Mission
The journey to geostationary orbit involved a series of precise maneuvers controlled by ISRO’s Master Control Facility at Hassan. The deployment of the satellite’s solar arrays and antenna reflector was meticulously executed, ensuring the satellite’s operational readiness. Two Ku-band beacon downlink signals are transmitted for accurate satellite tracking from the ground.
The geostationary orbit of GSAT-31 allows it to maintain a fixed position relative to the Earth, providing continuous coverage over a specific region. This is essential for uninterrupted communication services. The satellite’s 15-year mission life underscores its long-term contribution to India’s communication infrastructure.
ISRO’s Master Control and Orbit Raising Procedures
After the Ariane 5 launch and separation, ISRO’s Master Control Facility at Hassan took control of the GSAT-31. The facility monitored the satellite’s health parameters and initiated the phase-wise orbit-raising maneuvers. These maneuvers, utilizing the satellite’s on-board propulsion system, gradually increased the satellite’s altitude, eventually placing it in its final geostationary orbit. The deployment of the antenna reflector during the final stages ensured the satellite’s optimal configuration for satellite communication.
The Impact of GSAT-31 on Everyday Communication
For the average Indian citizen, the GSAT-31 launch translates to improved access to a range of services. Imagine a farmer in a remote village accessing real-time weather updates or agricultural advice through improved internet connectivity. Picture a student in the Andaman and Nicobar Islands attending online classes or accessing digital learning resources. Consider the convenience of seamless digital transactions and e-governance services, regardless of location.
These practical applications highlight the tangible benefits of space technology and the importance of investing in robust communication infrastructure. The GSAT-31 satellite is not just a technological marvel; it is a tool for empowerment and progress.
Future Implications and India’s Space Strategy
The GSAT-31 launch is a testament to India’s growing capabilities in the space sector. It reinforces ISRO’s commitment to developing and deploying advanced satellite communication systems that address the nation’s evolving needs. This mission also strengthens India’s position as a leading player in the global space arena.
Looking ahead, ISRO will continue to innovate and expand its satellite capabilities, focusing on enhancing digital connectivity, improving disaster resilience, and supporting sustainable development. The GSAT-31 satellite, with its advanced features and extended mission life, will play a crucial role in realizing these goals.
