Radar Imaging Satellite 1 or RISAT-1, was an Indian remote sensing satellite built and operated by the Indian Space Research Organisation (ISRO). The second RISAT satellite to be launched, it used a C-band 5.35 GHz synthetic-aperture radar (SAR) for Earth observation .

Radar Satellite-1 (RISAT-1) is a state of the art Microwave Remote Sensing Satellite carrying a Synthetic Aperture Radar (SAR) Payload operating in C-band (5.35 GHz), which enables imaging of the surface features during both day and night under all weather conditions.

Jan 11, 2024 · Launched in April 2012 and leaving service in March 2017, RISAT-1 (Radar Imaging Satellite 1) was the first satellite imaging mission independently developed by ISRO (Indian Space Research Organisation).

RISAT 1 (Radar Imaging Satellite 1) is the first satellite imaging mission of ISRO using an active C-band SAR (Synthetic Aperture Radar) imager. The objective of the RISAT mission is to use the all-weather as well as the day-and-night SAR observation capability in applications such as agriculture, forestry, soil moisture, geology, sea ice ...

RISAT-1 was an indigenously developed radar imaging satellite successfully launched by a PSLV-XL rocket on 26 April 2012 from Satish Dhawan Space Centre, Shriharikota. RISAT-1 was postponed in order to prioritize the building and launch of RISAT-2.

May 1, 2015 · RISAT 1 (Radar Imaging Satellite 1), an ISRO Earth observation satellite, was launched from Sriharikota Island on 26 April 2012 at 00:17 UT by a Polar Satellite Launch Vehicle (PSLV-XL). The satellite weighed 1858 kg making it the most massive spacecraft launched by …

The Polar Satellite Launch Vehicle, in its 21st flight (PSLV-C19), launches India’s first Radar Imaging Satellite – RISAT-1 into a Polar Circular Orbit with an altitude of 480 km (+ 40.5 km) and orbital inclination of 97.552 (+ 0.2).

May 2, 2012 · At 1,858 kilograms, RISAT 1 it is the heaviest Earth observation satellite ever launched by India, and the weightiest payload ever hoisted by the country's workhorse Polar Satellite Launch Vehicle, known as PSLV.

The RISAT-1 spacecraft has been built around the SAR payload in order to optimise the spacecraft weight and structure. The satellite is placed in a sun-synchronous orbit with 6 am-6 pm equatorial crossing, to maximize solar power availability.

A summary of the Radar Imaging Satellite (RISAT-1) Earth observation satellite mission from Committee on Earth Observing Satellites (CEOS). Mission status: mission complete, was launched on 26 April 2012, and ended on 26 April 2018. Operated by …
