News Desk <http://defense-update.com/author/news-desk> April 27, 2012 13:21 The Indian Space Research Organization launched yesterday the second radar imagery satellite, and the first indiginously built by the country's space research organization (ISRO). The satellite named Risat-1 successfully deployed into a polar orbit at an altitude of 480 km and orbital inclination 97.552 degrees. Risat-1 has an expected life span of five years. The satellite will provide high resolution radar images, obtained in day and night and also through clouds, enabling the country to continue monitoring areas of interest during the monsoon season. The satellite was launched at 5.47 a.m. on the Polar Satellite Launch Vehicle C19 (PSLV-C19). At around 17 minutes into the flight, PSLV-C19 delivered Risat-1 into an intermediate polar orbit at an altitude of 480 km and an orbital inclination of 97.552 degrees. Over the weekend the satellite will be elevated to its final intended orbit at an altitude of 536 km. With Thursday's launch the PSLV rocket has launched successfully 53 satellites out of 54 it carried majorly remote sensing/earth observation satellites both Indian and foreign and has been a major revenue earner for ISRO. The ISRO-made Risat-1 is the heaviest luggage so far ferried by a PSLV since 1993. India currently has 11 remote sensing and earth observation satellites in orbit, providing imagery at different resolution levels, from 500 meters to about one meter resolution. These spacecraft include the TES, Resourcesat-1, Cartosat-1, 2, 2A and 2B, IMS-1, Oceansat-2, Resourcesat-2 and Megha-Tropiques. Risat-1 joins Risat-2 in orbit, an Israeli SAR satellite launched in 2009. Both satellites carry synthetic aperture radars (SAR). Risat-1 operates in C-band while Risat-2â²s SAR works in the X-band. <http://defense-update.com/20120427_risat-1.html> [Non-text portions of this message have been removed] ------------------------------------ -------------------------- Want to discuss this topic?
