The polar satellite launch veichle (pslvc12)carrying two satellites will soar into the sky on today morning from the spaceport at Sriharkotta,Andhrapradhesh.It will put in orbit a radar imaging satellite called RISAT-2 and Anusat, a 38-kg. experimental mini communication satellite built by Anna University, Chennai.The mini-satellite carries a “store and forward payload.” Its secondary payloads are micro electro mechanical systems (MEMS), a MEMS gyroscope, a MEMS magnetometer and a satellite positioning system. The primary payload will enable its receiver to receive the information and its transmitter to read the information to the ground station when it is passing over an intended area.Anusat will last for a year.Its users be Madrass Instiute of Technology Chennai.The current launch vehicle is a core-alone version – without the six strap-on booster motors that form part of the standard PSLV. The core-alone vehicle, which looks sleek and elegant, weighs 230 tonnes while a normal PSLV weighs 295 tonnes. The rocket is 44 metres tall. It is a four-stage vehicle, with alternate stages powered by solid and liquid propellants.
