India’s Polar Satellite Launch Vehicle, in its 40th flight (PSLV-C38), will launch the 712 kg Cartosat-2 series satellite for earth observation and 30 co-passenger satellites together weighing about 243 kg at lift-off into a 505 km polar Sun Synchronous Orbit (SSO). PSLV-C38 will be launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. This will be the seventeenth flight of PSLV in ‘XL’ configuration (with the use of solid strap-on motors).
Cartosat-2E is an Earth observation satellite developed by the Indian Space Research Organisation (ISRO), and is the seventh in the Cartosat series. It is designed to collect high-resolution, large-scale imagery for use in urban planning, infrastructure development, utilities planning, and traffic management.
The satellite is planned for launch on 23 June 2017 aboard a PSLV-XL rocket from the Satish Dhawan Space Centre First Launch Pad. Massing 712 kilograms (1,570 lb), it will be deployed into a 505-kilometre (314 mi) Sun-synchronous orbit for a five-year primary mission. India has allocated ₹160 crore for the project.
Cartosat-2E carries two primary instruments: the Panchromatic Camera (PAN) and the High-Resolution Multi-Spectral radiometer (HRMX). PAN is capable of taking panchromatic (black and white) photographs in a selected portion of the visible and near-infrared spectrum (0.50–0.85 µm) at a resolution of 65 centimetres (26 in). HRMX is a four-channel radiometer sensitive across the entire visible spectrum and part of the near-infrared spectrum (0.43–0.90 µm) at a resolution of 2 metres (6.6 ft).
The co-passenger satellites comprise 29 Nano satellites from 14 countries namely, Austria, Belgium, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, United Kingdom, and United States of America as well as one Nano satellite from India. The total weight of all these satellites carried on-board PSLV-C38 is about 955 kg.
The 29 International customer Nano satellites are being launched as part of the commercial arrangements between Antrix Corporation Limited (Antrix), a Government of India company under Department of Space (DOS) and the commercial arm of ISRO and the International customers.
About Cartosat series –
The Cartosat series of satellites are a type of earth observation satellites indigenously built by India. Up till now 6 Cartosat satellites have been launched by ISRO. The Cartosat series is a part of the Indian Remote Sensing Programme. They were specifically launched for Earth’s resource management and monitoring.
The first Cartosat satellite was Cartosat-1 which was launched by PSLV-C6, on May 5th 2005 from the then newly built Second Launch Pad at Sriharikota. Department of Space (DOS), Government of India had earlier launched a series of satellites for Earth’s resource management and monitoring. These satellites had been very successful in providing data in various scales ranging from 1:1 Million to 1:12,500 scale. Each of the Indian Remote Sensing satellite missions ensured data continuity while introducing improvements in the spatial, spectral and radiometric resolutions. Considering increase demand for large scale and topographic mapping data DOS launched the Cartosat-1 in 2005.
Cartosat-1 was launched by PSLV-C6 on 5 May 2005 from Satish Dhawan Space Centre’s SLP at Sriharikota. Images from the satellite is available from GeoEye for worldwide distribution. The satellite covers the entire globe in 1867 orbits on a 126-day cycle. It carries two state-of-the-art panchromatic (PAN) cameras that take black and white stereoscopic pictures of the earth in the visible region of the electromagnetic spectrum. The two cameras with 2.5 m spatial resolution, acquire two images simultaneously, one forward looking (FORE)at +26 degrees and one aft of the satellite at -5 degrees for near instantaneous stereo data. The time difference between the acquisitions of the same scene by the two cameras is about 52 seconds.
Cartosat-2 was launched by PSLV-C7 on 10 January 2007 from Satish Dhawan Space Centre’s FLP at Sriharikota. Cartosat-2 carries a state-of-the-art panchromatic (PAN) camera that take black and white pictures of the earth in the visible region of the electromagnetic spectrum. The swath covered by this high resolution PAN camera is 9.6 km and their spatial resolution is less than 1 metre. The satellite can be steered up to 45 degrees along as well as across the track. Cartosat-2 is an advanced remote sensing satellite capable of providing scene-specific spot imagery. The data from the satellite is used for detailed mapping and other cartographic applications at cad-astral level, urban and rural infrastructure development and management, as well as applications in Land Information System (LIS) and Geographical Information System (GIS).
Cartosat-2A was launched by PSLV-C9 on 28 April 2008 from Satish Dhawan Space Centre’s SLP at Sriharikota along with 9 other satellites. It is a dedicated satellite for the Indian Armed Forces which is in the process of establishing an Aerospace Command. The satellite carries a panchromatic (PAN) camera capable of taking black-and-white pictures in the visible region of electromagnetic spectrum. The highly agile Cartosat-2A can be steered up to 45 degrees along as well as across the direction of its movement to facilitate imaging of any area more frequently.
Cartosat-2B was launched by PSLV-C15 on 12 July 2010 from Satish Dhawan Space Centre’s FLP at Sriharikota. The satellite carries a panchromatic (PAN) camera capable of taking black-and-white pictures in the visible region of electromagnetic spectrum. The highly agile CARTOSAT-2B can be steered up to 26 degrees along as well as across the direction of its movement to facilitate imaging of any area more frequently.
Cartosat-2C is a much more capable satellite, having a resolution of 25 cm (10″). It uses 1.2 m optics with 60% of weight removal compared to Cartosat-2. Other features include the use of adaptive optics, acousto optical devices, in-orbit focusing using MEMs and large area-light weight mirrors. The satellite was to be launched on board PSLV during 2014, but had been delayed and was finally launched on 22 June 2016. Potential uses include weather mapping, cartography, and strategic applications.
Cartosat-2D was launched by PSLV-C37 on 15 February 2017 from Satish Dhawan Space Centre’s FLP at Sriharikota.
Cartosat-2E will launched by PSLV-C38 on 23 June 2017 from Satish Dhawan Space Centre’s FLP at Sriharikota.The PSLV-C38 rocket would launch the 550kg satellite, the fourth of the Cartosat-2 series.
