India's spy satellite, built by Israel, is undergoing final stages of testing and integration at the spaceport of Sriharikota in Andhra Pradesh for an April 20 launch.
The 300-kg radar imaging satellite, which would primarily keep a watch on movements on the borders and help the country in anti-infiltration and anti-terrorist operations, is set to be launched on board the 230-tonne core-alone, home-grown rocket Polar Satellite Launch Vehicle without strap-on motors in view of the light weight of the payload.
"The satellite is expected to be launched at around 6.45 am", an Indian Space Research Organisation (ISRO) official told PTI here today.
The Bangalore-based space agency has kept the mission low-profile, given the sensitivenessof the venture.
Top ISRO officials, including the agency's Chairman G Madhavan Nair, are expected to address a media conference after the launch on Monday.
This imaging satellite, built by Israel Aerospace Industries, has all-weather capabilities which means it can take pictures during day and night and under cloud cover.
In addition to surveillance applications, the spacecraft will add to the capabilities of ISRO in managing disasters like cyclones, floods and landslides.
Anusat, a 40-kg satellite built by Chennai-based Anna University, is the co-passenger on board PSLC-C12.
