Not sure whether it can provide 300km trans frontier coverage into India, but never the less a potent system and a great complement to our existing radar coverage which is exceptional. Heres some info:
VERA S/M Passive Surveillance System
The VERA S/M is a product of the ERA Inc. of Pardubice in the Czech Republic. The system, as an independent source of information on air situation, can meet tasks of a monitoring and a back-up system for radar systems of the Air Traffic Control Centre of the Czech Republic.
The prototype of the VERA system has been first installed at the elevation of about 1000 metres and from 1995 it has been successfully tested in round-the-clock and permanent operation by a group of experts from the Air Force Passive Systems Centre and from Air Defence Command of the Army of the Czech Republic. It has used the improved working method first introduced in its predecessors (e.g. TAMARA or TACAN surveillance systems).
The manufacturer offers the system also in the following modifications: VERA P3D, VERA ASCS, VERA - AP, VERA - ADSB and VERA HME and VERA E, and S/M, used predominantly by the military.
The testing has proven that the system has an operation range of 400 to 500 kilometres in an angle higher than 120 degrees. The software presently used is capable of automatic and simultaneous tracking of up to 300 aircraft/targets at the real time.
The crew is a single operator, plus an officer.
The PSS VERA is a useful complement and a back-up of existing active radars of air traffic control centres, without ambition to replace them.

Dude DOB is no troll, she is a very highly respected member on this board and her knowledge in matters of Military Aviation far exceeds our. Show some respect, instead of posting a reply like that you should have answered the question.
