NEW DELHI: The stage is finally set for the launch of the country's heaviest satellite Gsat-11 , weighing 5,854 kg, from French Guiana by Europe's Ariane-5 rocket early on Wednesday morning. European space transporter Arianespace, on its website, said the launch window is between 2.07am and 3.23am (IST) on December 5.The communication satellite, which will help increase internet speed in the country, was earlier scheduled for launch early this year but suspecting a glitch in the system the Indian space agency recalled it from French Guiana to check for possible anomalies. Indian Space Research Organisation Isro ) felt the need to take the unusual step of recalling the satellite in April as a precaution measure especially after the failure of the Gsat-6A mission around the same time. Gsat-6A satellite went out of control and signal from it was lost soon after its launch on March 29.Gsat-11 is a high-throughput satellite that carries 40 transponders in the Ku-band and Ka-band frequencies and is capable of "providing high bandwidth connectivity" with up to 14 gigabit per second (GBPS) data transfer speed. The satellite's designed lifetime is more than 15 years.Isro chairman K Sivan recently told TOI that the "launch of four high-throughput satellites will provide the country broadband connectivity of over 100 gigabits per second (Gbps) by next year." Of the four, two satellites Gsat-19 and Gsat-29 have already been launched. Gsat-11 will be launched on Wednesday and Gsat-20 launch has been scheduled next year. He said, "Together, all these satellites will provide high-speed internet connectivity in the country, especially in rural areas, and help bridge the digital divide."Gsat-11 is meant to provide multi-spot beam coverage over the India mainland and nearby islands, bringing significant advantages to users when compared with the country's existing Insat/Gsat satellite systems. It will also provide a platform to demonstrate new-generation applications. The heavy-duty satellite is so massive that each solar panel is over four metres long, equivalent to the size of a big room.The satellite will be initially be placed in the geosynchronous transfer orbit and subsequently be raised to geostationary orbit by firing the Liquid Apogee Motor on-board the satellite. Besides India's Gsat-11, the heavy-lift Ariane-5 vehicle will also carry GEO-KOMPSAT-2A for the Korea Aerospace Research Institute.
