The Indian Space Research Organisation’s first radar imaging satellite, RISAT-1, is scheduled to be launched from the Satish Dhawan Space Centre, Sriharikota on Thursday. A launch authorization board on April 21 cleared the mission for which a 71-hour countdown began at 6.47am on Monday. The microwave remote sensing satellite is carrying a Synthetic Aperture Radar (SAR).An Isro release said the satellite can capture aerial pictures of the earth in any weather — rainy, sunny, cloudy, foggy or cyclonic.
To be launched by PSLVC19(XL), the 1,850 kg RISAT-1, the heaviest remote sensing satellite built by ISRO, has been in the making for 10 years. It will first be put in orbit at an altitude of 480 km at an inclination of 97.552 deg before settling in its final orbital configuration at an altitude of 536 km. Propellant-filling operations of the liquid Propellant Second stage (PS2) and fourth stage (PS4) are being carried out. “Mandatory checks on the launch vehicle, including charging batteries and pressurizing propellant tanks, are being carried out. The readiness of various ground systems such as tracking radar systems and communication networks will also be checked,” said an official release.
