QuickBird was a high-resolution commercial Earth observation satellite, owned by DigitalGlobe, launched in 2001 and reentered after orbit decay in 2015. QuickBird used Ball Aerospace's Global Imaging System 2000. The satellite collected panchromatic imagery at 61 centimeter resolution and multispectral imagery at 2.44- to 1.63-meter resolution, as orbit altitude is lowered during the end of mission life.
India's remote sensing program was developed with the idea of applying space technologies for the benefit of humankind and the development of the country. The program involved the development of three principal capabilities. The first was to design, build and launch satellites to a Sun-synchronous orbit. The second was to establish and operate ground stations for spacecraft control, data transfer along with data processing and archival. The third was to use the data obtained for various applications on the ground.
Cartosat-1 is a stereoscopic Earth observation satellite in a Sun-synchronous orbit, and the first one of the Cartosat series of satellites. The eleventh satellite of ISRO in Indian Remote Sensing Satellite (IRS) series. The satellite was launched by Indian Space Research Organisation and is operated by NTRO. Weighing around 1560 kg at launch, its applications will mainly be towards cartography in India.
Resourcesat-1 is an advanced remote sensing satellite built by Indian Space Research Organization (ISRO). The tenth satellite of ISRO in IRS series, Resourcesat-1 is intended to not only continue the remote sensing data services provided by IRS-1C and IRS-1D, both of which have far outlived their designed mission lives, but also vastly enhance the data quality.
China–Brazil Earth Resources Satellite 2B (CBERS-2B), also known as Ziyuan 1-2B, was a remote sensing satellite operated as part of the China–Brazil Earth Resources Satellite program between the Chinese Center for Resources Satellite Data and Application and Brazilian National Institute for Space Research. The third CBERS satellite to fly, it was launched by China in 2007 to replace CBERS-2.
China–Brazil Earth Resources Satellite 1 (CBERS-1), also known as Ziyuan I-01 or Ziyuan 1A, is a remote sensing satellite which was operated as part of the China–Brazil Earth Resources Satellite program between the China National Space Administration and Brazil's National Institute for Space Research. The first CBERS satellite to fly, it was launched by China in 1999.
The Integrated Space Cell was the nodal agency within the Government of India with oversight of the security of its space based military and civilian hardware systems. It was to be jointly operated by all the three services of the Indian Armed Forces, the civilian Defence Research and Development Organisation and the Indian Space Research Organisation (ISRO). This agency was superseded by Defence Space Agency in 2019.[better source needed]
Resourcesat-2 is a follow on mission to Resourcesat-1 and the eighteenth Indian remote sensing satellite built by Indian Space Research Organisation (ISRO). The new satellite provides the same services as the original Resourcesat-1, but was also designed to "provide data with enhanced multispectral and spatial coverage". Compared to Resourcesat-1, LISS-4 multispectral swath has been enhanced from 23 km to 70 km based on user needs. Suitable changes including miniaturization in payload electronics have been incorporated in Resourcesat-2.
China–Brazil Earth Resources Satellite 2 (CBERS-2), also known as Ziyuan I-02 or Ziyuan 1B, was a remote sensing satellite operated as part of the China–Brazil Earth Resources Satellite program between the Chinese Center for Resources Satellite Data and Application and Brazilian National Institute for Space Research. The second CBERS satellite to fly, it was launched by China in 2003 to replace CBERS-1.
IRS-1D is the seventh satellite in Indian Remote Sensing satellite series of Earth Observation satellites, built, launched and maintained by Indian Space Research Organisation (ISRO). The satellite has similar capabilities as that of ISRO's IRS-1C satellite with some improvements added for better imagery particularly in thematic mapping.
BILSAT-1 was an Earth observation satellite designed and developed by TÜBİTAK Space Technologies Research Institute and produced in Turkey as part of the Disaster Monitoring Constellation (DMC) project in the context of a show-how program led by DMC International Imaging of Surrey Satellite Technology (SSTL).
IRS-P2 was an Earth observation satellite launched under the National Natural Resources Management System (NNRMS) programme undertaken by Indian Space Research Organisation (ISRO). The objectives of the mission were to provide spaceborne capability to India in observing and managing natural resources and utilizing them in a productive manner. The satellite carried imaging multi-spectral radiometers on board for radio sensing of the resources.
IRS-1C was the fifth remote sensing Indian satellite built, and designed by Indian Space Research Organization (ISRO). IRS-1C is first second-generation operational Remote Sensing Satellite. The satellite carries payloads with enhanced capabilities like better spatial resolution additional spectral bands, improved repeatability and augment the remote sensing capability of the existing IRS-1A and IRS-1B.
IRS-1E was an Earth observation mission launched under the National Natural Resources Management System (NNRMS) programme by Indian Space Research Organisation (ISRO). Sometimes written IRS-P1. The objective of the mission was to develop Earth imagery using instruments carried on board. Due to a malfunction of the launch vehicle, the satellite deviated from its path and plunged into the Indian Ocean.
IRS-1A, Indian Remote Sensing satellite-1A, the first of the series of indigenous state-of-art remote sensing satellites, was successfully launched into a polar Sun-synchronous orbit on 17 March 1988 from the Soviet Cosmodrome at Baikonur. IRS-1A carries two sensors, LISS-1 and LISS-2, with resolutions of 72 m (236 ft) and 36 m (118 ft) respectively with a swath width of about 140 km (87 mi) during each pass over the country. Undertaken by the Indian Space Research Organisation (ISRO). It was a part-operational, part-experimental mission to develop Indian expertise in satellite imagery.
Oceansat-1 or IRS-P4 was the first Indian satellite built primarily for ocean applications. It was a part of the Indian Remote Sensing Programme satellite series. The satellite carried an Ocean Colour Monitor (OCM) and a Multi-frequency Scanning Microwave Radiometer (MSMR) for oceanographic studies. Oceansat-1 thus vastly augment the IRS satellite system of Indian Space Research Organisation (ISRO) comprising four satellites, IRS-1B, IRS-1C, IRS-P3 and IRS-1D and extend remote sensing applications to several newer areas.
Haiyang is a series of marine remote sensing satellites developed and operated by the People's Republic of China since 2002. As of October 2022, eight satellites have been launched with ten more planned. Built by the state-owned aerospace contractor China Academy of Space Technology (CAST), Haiyang satellites carry a variety of ocean-imaging sensor payloads and are operated by the National Satellite Ocean Application Service (NSOAS), a subordinate agency of the State Oceanic Administration (SOA). Haiyang satellites are launched from Taiyuan Satellite Launch Center (TSLC) into Sun-synchronous orbit (SSO) aboard Long March-series rockets.
PSLV-C5 was the fifth operational launch and overall eighth mission of the Polar Satellite Launch Vehicle program. This launch was also the fifty-second launch by the Indian Space Research Organisation (IRSO) since its first mission on 1 January 1962. The vehicle carried and injected India's remote sensing satellite Resourcesat-1 into a Sun-synchronous orbit; this was the heaviest and most sophisticated satellite built by IRSO through 2003. PSLV-C5 was launched at 04:52 hours Coordinated Universal Time on 17 October 2003 from Satish Dhawan Space Centre.
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.
HySIS is an Earth observation satellite which will provide hyperspectral imaging services to India for a range of applications in agriculture, forestry and in the assessment of geography such as coastal zones and inland waterways The data will also be accessible to India's defence forces.
