Green pine is for Indian BMD for its initial phases of development.

Why cant a geo-stat satellite provide real time input to the seeker of BMD missile?? Havent you heard Techsar is a SAR (Synthetic aperture Radar) Although for different purpose.
Havent you heard of Glonass at all?
Sir, Glonass is for providing guidance in navigation once you have the target coordinates not for target acquisition. Missile launch detection from space generally employs infrared sensors.
From global security: Missile Defense Infrared Sensors
Remote sensing of visual, ultraviolet, and infrared sources currently employ electro-optical detection systems. The detection systems are mounted on platforms supported by satellites, airplanes, ships or land based vehicles. The detection systems include an electro-optical or optical sensor, typically a telescope, for collecting photons representative of a target and a detector for converting these collected photons into electrons and hence an electronic current. This enables information to be gathered about the target.
Traditionally, strategic and tactical missile launch detection and tracking systems use infrared surveillance techniques employed by satellite sensors. The satellite sensors are required to view the whole earth at one time because the missiles could be launched from any location. It is necessary to determine where the missile is going and, from the trajectory, to find where the missile is likely to hit with a high probability of detection. For example, it is usually required to have a probability of detection of at least 99% and to avoid a false detection to a probability of less than once per month.
