GSAT 11 going to Launch this Year
GSAT-11 is an Indian communication satellite which is proposed to be launched by GSLV-MkIII, an indigenously developed spacecraft propelled by cryogenic engine. The satellite is aimed at providing advanced telecom and DTH services in the country. GSAT-11 can transmit data at a speed of 10 Gigabytes per second to the entire nation.
Satellite GSAT-11 will be developed at the cost of Rs. 500 crore. At 4.5 tonnes, it will weigh more than twice as much as the biggest Indian satellite in orbit now. With 16 high capacity multi-beams in Ku/Ka band, GSAT-11 will provide much faster uplinks for a host of communications and broadcasting services, including direct-to-home (DTH television). With a dry mass of 2.1 tonne, the spacecraft will provide 10 GHz of bandwidth, which will be equivalent to about 220 transponders of 36 MHz. The advanced satellite will employ a new I-4K satellite bus. It will be configured with two-sided large solar array panels generating 11 KW of power. GSAT-11 to be located at 74 deg E is an advanced communication satellite with multi spot beam antenna coverage over Indian mainland as well as Islands to bring-in a huge advantage to the user community, compared to the existing INSAT/GSAT satellite systems. The main highlights of the system configuration are multi beam coverage, Star network based Gateway connectivity, ACM as fade mitigation techniques, on-board power management techniques etc. In addition to the advanced on-board technologies that are considered, the ground system technologies with user terminals employing Adaptive Coding & Modulation techniques, site diversity for Ka band Hub stations & sizing for fade mitigation etc are built into the design of overall system. Type/Applications: Communications Orbit Location: 74°E Geo Mission Life: 15 Years Equipments: 32 Ka x Ku Transponders 8 Ku x Ka Transponders Configuration: I4K Bus Frequency: Ka x Ku: U/L: 27000 – 27500 MHz, 29500 – 30000 MHz (LV & LH) D/L: 10700 – 10950 MHz, 11200 – 114500 MHz (LV & LH) Ku x Ka: U/L: 12750 – 13250 MHz (LV & LH) D/L: 18100 – 18600 MHz, 19700 – 20200 MHz (LV & LH) Coverage: · 16 Ku-band beams covering Indian mainland & Islands in both polarizations · 2 Ka-band beams over New Delhi & Bangaluru |
