List Of GSLV Launches
This is a list of launches conducted by the Indian Space Research Organisation (ISRO) using Geosynchronous Satellite Launch Vehicle (GSLV) rockets. This list does not include LVM3 (formerly known as GSLV Mk III) launches, which can be found here. Notable missions GSLV MK. I flight D1 This was the first developmental flight of the GSLV Mk.I featuring Russian cryogenic engine KVD-1. It was used to place an experimental satellite GSAT-1 into the orbit. However, due to sub-optimal performance and lack of fuel the vehicle did not achieve the intended orbit and the satellite had to maneuver itself using onboard fuel to correct the shortfall. ISRO claims the launch to be successful. In a 2014 interview, ISRO Chairman K. Radhakrishnan attributed the failure to incorrect mixture ratio used in the cryogenic upper stage. GSLV MK. II flight D5 This was the second test flight with indigenous cryogenic stage CE-7.5 and the first successful launch with the CE-7.5. The flight lifte ...

GSAT-5P
GSAT-5P, or GSAT-5 Prime, was an Indian communications satellite which was lost in a launch failure in December 2010. Part of the Indian National Satellite System, it was intended to operate in geosynchronous orbit as a replacement for INSAT-3E. Satellite GSAT-5P was a spacecraft, which was built by the Indian Space Research Organisation based on the I-2K satellite bus. ISRO also launched the satellite, and was to have been responsible for its operation. It was equipped with 36 transponders operating in the G/ H band of the NATO-defined spectrum, or the C band of the older IEEE spectrum. Twelve of the transponders operated on extended frequencies within the band. GSAT-5P was expected to operate for at least 12 years, and would have been placed at a longitude of 55 degrees east. Launch The launch of GSAT-5P used a Geosynchronous Satellite Launch Vehicle Mk.I, serial number F06, and took place from the Second Launch Pad at the Satish Dhawan Space Centre. The rocket featured s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GSAT-4
GSAT-4, also known as HealthSat, was an experimental communication satellite, communication and navigation satellite, navigation satellite launched in April 2010 by the Indian Space Research Organisation on the maiden flight of the Geosynchronous Satellite Launch Vehicle Mk.II rocket. It failed to reach orbit after the rocket's third stage malfunctioned. The third stage was the first Indian-built Cryogenic fuel, cryogenic-fuelled upper stage, and was making its first flight. The ISRO suspects that the failure was caused by the third stage not igniting. Satellite Weighing around two tons, GSAT-4 carried a multi-channel, Ka-band, bent pipe and regenerative transponder, and a navigation payload in the C, L1, and L5 bands. Designed to guide civil and military aircraft, GSAT-4 was to have employed several new technologies such as a bus management unit, miniaturised dynamically tuned gyros, lithium-ion battery, 70 volt bus for Ka-band traveling-wave tube amplifiers, travelling-wave tube ...

INSAT-4CR
INSAT-4CR was a communications satellite operated by ISRO as part of the Indian National Satellite System. Launched in September 2007, it replaced the INSAT-4C satellite which had been lost in a launch failure the previous year. The satellite was initially stationed in geostationary orbit at a longitude of 74 degrees east, with expected operational life of at least ten years, however this may have been reduced by the underperformance of the Geosynchronous Satellite Launch Vehicle which placed it into orbit. INSAT-4CR is planned to be replaced by GSAT-31, which was launched on February 6, 2019. Spacecraft INSAT-4CR was constructed by ISRO, and is based around the I-2K satellite bus. A spacecraft, it is equipped with twelve Ku band transponders operating at a frequency of 36 MHz, with 140 Watt travelling wave tube amplifiers. The satellite has an effective isotropic radiated power of 51.5 dBW. An additional Ku band signal is used as a beacon for tracking. INSAT-4CR operated ...

INSAT-4C
INSAT-4C was an Indian communications satellite which was lost in a launch failure in 2006. Had it reached orbit, it would have formed part of the Indian National Satellite System. Launched in 2007, it was intended to have operated in geostationary orbit at a longitude of 73.97° east. The INSAT-4CR satellite, launched in September 2007, replaced it. Built by the Indian Space Research Organisation, INSAT-4C was based upon the I-2K satellite bus. It had a dry mass of , or when fully fuelled. It was expected to have operated for ten years. The satellite carried twelve Ku band transponders, with two solar arrays to generate power. ISRO launched INSAT-4C on the second operational flight of the Geosynchronous Satellite Launch Vehicle, which was flying in the Mk.I configuration. The launch took place from the Second Launch Pad at the Satish Dhawan Space Centre Satish Dhawan Space Centre – SDSC (formerly Sriharikota Range – SHAR) is the primary spaceport of the Indian S ...

GSAT-3
GSAT-3, also known as EDUSAT, was a communications satellite which was launched on 20 September 2004 by the Indian Space Research Organisation. EDUSAT is the first Indian satellite built exclusively to serve the educational sector. It is mainly intended to meet the demand for an interactive satellite-based distance education system for the country. EDUSAT carries five Ku band transponders providing spot beams, one Ku band transponder providing a national beam and six extended C band transponders providing national coverage beams. EDUSAT was successfully launched into a Geosynchronous Transfer Orbit (GTO) on the first operational launch of the Geosynchronous Satellite Launch Vehicle, which flew from the First Launch Pad at the Satish Dhawan Space Centre in Sriharikota. EDUSAT was initially placed into a transfer orbit with a perigee of and an apogee of and a period of 10.5 hours, inclined at 19.2 degrees to the equator. EDUSAT was decommissioned in September 2010 and r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Coordinated Universal Time
Coordinated Universal Time (UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce. UTC has been widely embraced by most countries and is the effective successor to Greenwich Mean Time (GMT) in everyday usage and common applications. In specialised domains such as scientific research, navigation, and timekeeping, other standards such as Universal Time, UT1 and International Atomic Time (TAI) are also used alongside UTC. UTC is based on TAI (International Atomic Time, abbreviated from its French name, ''temps atomique international''), which is a weighted average of hundreds of atomic clocks worldwide. UTC is within about one second of mean solar time at 0° longitude, the currently used prime meridian, and is not adjusted for daylight saving time. The coordination of t ...
