RISAT-1/PSLV-C19 Integration смотреть онлайн

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.

Application

Active Microwave Remote Sensing provides cloud penetration and day-night imaging capability. These unique characteristics of C-band (5.35GHz) Synthetic Aperture Radar enable applications in agriculture, particularly paddy monitoring in kharif season and management of natural disasters like flood and cyclone.

PSLV-C19

The Polar Satellite Launch Vehicle, in its 21st flight (PSLV-C19), will launch India's first Radar Imaging Satellite -- RISAT -1 into a Polar Circular Orbit with and altitude of 480 km (+- 40.5 km) and orbital inclination of 97.552° deg (+-0.2° ). RISAT-1 weighing 1858 kg is the heaviest satellite being launched by PSLV as on April 2012

This is the third flight of the high end version (PSLV-XL) with six extended strap-on motors, eqach carrying 12 tonnes of solid propellant. (The two earlier flights of PSLV-XL were used to launch Chandrayaan-1 and GSAT-12 Communication Satellite)
