The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO).
The Indian National Satellite System or INSAT, is a series of multipurpose geostationary satellites launched by ISRO to satisfy the telecommunications, broadcasting, meteorology, and search and rescue operations. Commissioned in 1983, INSAT is the largest domestic communication system in the Indo-Pacific Region. It is a joint venture of the Department of Space, Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. The overall coordination and management of INSAT system rests with the Secretary-level INSAT Coordination Committee.
The GPS-aided GEO augmented navigation (GAGAN) is an implementation of a regional satellite-based augmentation system (SBAS) by the Government of India. It is a system to improve the accuracy of a GNSS receiver by providing reference signals. The Airports Authority of India (AAI)'s efforts towards implementation of operational SBAS can be viewed as the first step towards introduction of modern communication, navigation and surveillance / air traffic management system over the Indian airspace.
The Indian Regional Navigation Satellite System (IRNSS), with an operational name of NavIC, is an autonomous regional satellite navigation system that provides accurate real-time positioning and timing services. It covers India and a region extending 1,500 km (930 mi) around it, with plans for further extension. An extended service area lies between the primary service area and a rectangle area enclosed by the 30th parallel south to the 50th parallel north and the 30th meridian east to the 130th meridian east, 1,500–6,000 km (930–3,730 mi) beyond borders where some of the NavIC satellites are visible but the position is not always computable with assured accuracy. The system currently consists of a constellation of eight satellites, with two additional satellites on ground as stand-by.
IRNSS-1A is the first navigational satellite in the Indian Regional Navigation Satellite System (IRNSS) series of satellites been placed in geosynchronous orbit.
GSAT-10 is an Indian communication satellite which was launched by Ariane-5ECA carrier rocket in September 2012. It has 12 KU Band, 12 C Band and 6 lower extended c band transponders, and included a navigation payload to augment GAGAN capacity. Following its launch and on-orbit testing, it was placed in Geosynchronous orbit at 83.0° East, from where it will provide communication services in India.
IRNSS-1B is the second out of seven in the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A. The IRNSS constellation of satellites is slated to be launched to provide navigational services to the region. It was placed in geosynchronous orbit on 4 April 2014.
IRNSS-1C is the third out of seven in the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A and IRNSS-1B. The IRNSS constellation of satellites is slated to be launched to provide navigational services to the region. It was launched on 15 October 2014 at 20:02 UTC by PSLV-C26 and will be placed in geostationary orbit.
IRNSS-1D is a satellite in the Indian Regional Navigational Satellite System (IRNSS) constellation. The satellite is the fourth of seven in the constellation, launched after IRNSS-1A, IRNSS-1B and IRNSS-1C. The satellite is the only satellite in the constellation slated to provide navigational services to the region. The satellite will be placed in geosynchronous orbit. It was launched successfully on 28 March 2015 onboard ISRO's PSLV-C27 from Satish Dhawan Space Center, Sriharikota.
IRNSS-1F is the sixth navigation satellite out of seven in the Indian Regional Navigational Satellite System (IRNSS) series of satellites after IRNSS-1A, IRNSS-1B, IRNSS-1C, IRNSS-1D and IRNSS-1E. The satellite is one among the seven of the IRNSS constellation of satellites launched to provide navigational services to the region.
IRNSS-1G was the seventh and final of the Indian Regional Navigation Satellite System (IRNSS) series of satellites after IRNSS-1A, IRNSS-1B, IRNSS-1C, IRNSS-1D, IRNSS-1E and IRNSS-1F. This system of satellites will provide navigational services to the Indian region. The satellite was launched successfully on 28 April 2016 at 07:20 UTC.
PSLV-C34 was the 36th mission of the PSLV program and 14th mission of PSLV in XL configuration. The PSLV-C34 successfully carried and deployed 20 satellites in the Sun-synchronous orbit. With a launch mass of 320,000 kilograms (710,000 lb) and payload mass of 1,288 kilograms (2,840 lb), the C34 set a new record of deploying the maximum number of satellites by Indian Space Research Organisation in a single mission. The PSLV-C34 carried One Cartosat-2 satellite, SathyabamaSat, Swayam & 17 other satellites from United States, Canada, Germany & Indonesia.
Resourcesat-2A is a follow on mission to Resourcesat-1 and Resourcesat-2 which were launched in October 2003 and in April 2011 respectively. The new satellite provides the same services as the other Resourcesat missions. It will give regular micro and macro information on land and water bodies below, farm lands and crop extent, forests, mineral deposits, coastal information, rural and urban spreads besides helping in disaster management.
PSLV-C37 was the 39th mission of the Indian Polar Satellite Launch Vehicle (PSLV) program and its 16th mission in the XL configuration undertaken by the Indian Space Research Organisation (ISRO). Launched on 15 February 2017 from the Satish Dhawan Space Centre at Sriharikota, Andhra Pradesh, the rocket successfully carried and deployed a record number of 104 satellites in sun-synchronous orbits in a single mission, breaking the earlier record of launching 37 satellites by a Russian Dnepr rocket on 19 June 2014.
IRNSS-1H was the eighth in the Indian Regional Navigational Satellite System (IRNSS) series of satellites, after IRNSS-1A, IRNSS-1B, IRNSS-1C, IRNSS-1D, IRNSS-1E, IRNSS-1F and IRNSS-1G. It was lost in the launch failure of PSLV-C39 on August 31, 2017.
Polar Satellite Launch Vehicle – C39 was the forty-first flight of the PSLV series of launch vehicles on 31 August 2017. Launched in its XL configuration, the vehicle suffered a rare failure – the first failure after 24 years of operations when the heat shield failed to separate and the payload became trapped inside the heat shield and could not be deployed.
IRNSS-1I is the eighth satellite in the Indian Regional Navigational Satellite System (IRNSS) series of satellites, in reality, IRNSS - 1I is the ninth satellite that launched in IRNSS constellation but it is counting as eighth satellite because IRNSS - 1I is an eighth satellite that has launched successfully in IRNSS constellation. ISRO already launched IRNSS-1A, IRNSS-1B, IRNSS-1C, IRNSS-1D, IRNSS-1E, IRNSS-1F, IRNSS-1G and IRNSS-1H. The satellite is intended to replace the failed IRNSS-1A, and complete the constellation of geosynchronous navigation satellites after IRNSS-1H failed to do so. The satellite's assembly, integration and testing is partly done by a consortium of six small firms led by Alpha Design Technologies, a Bengaluru-based aerospace firm under URSC's supervision.
