India by developing IRNSS has achieved another milestone in space, civil and military technology. It will guide our weapons accurately to the targets, keep an eye on the enemy, SAR operations, fly our aircrafts etc etc.

About nine years back, the Indian Space Research Organisation’s scientists and engineers began to look at the possibility of establishing a navigation satellite system for the country, rather like America’s Global Positioning System (GPS).
Like the GPS, the Indian satellites would continually transmit data that allowed suitably equipped receivers to establish their location with considerable precision. The GPS requires a constellation of 24 orbiting satellites, supported by a global network of ground stations, to cover every part of the world. That kind of global system is expensive.
ISRO had a more limited goal — creating a system wholly in India's control for providing navigation signals over this country and surrounding areas. The cost of such a system was a major consideration.
“We looked at many thousands of configurations,” said one person who was involved in those early studies. The configuration that was finally chosen for the Indian Regional Navigation Satellite System (IRNSS) required just seven satellites.
All seven IRNSS satellites will be at a height of about 36,000 km, taking a whole day to circle the Earth. Three of the satellites will be placed over the equator, in what is known as the geostationary orbit, where they match the Earth's rotation and therefore appear from the ground to remain at a fixed position in the sky. The remaining four satellites will be in pairs in two inclined geosynchronous orbits. From the ground, these satellites will appear to travel in figures of ‘8’ during the course of a day.
The project to establish the IRNSS at a cost of Rs. 1,420 crores was approved by the Union Government in June 2006. The primary service area for the system covers India and up to 1,500 km beyond its borders.
If necessary, the coverage area around India could be enhanced by adding four satellites, the ISRO Chairman, K. Radhakrishnan, told The Hindu.
The first of the IRNSS satellites is scheduled go into space aboard the Polar Satellite Launch Vehicle on July 1.
Rubidium Atomic Clock for Space developed by NPL, Ahmadabad
CSIR-NPL has developed and transferred the critical technology of Rubidium atomic clock for space applications to ISRO. A model has been developed at CSIR-NPL and is undergoing further developments at Satellite Applications Center before being integrated in the payload of the Indian Regional Navigation Satellite system.
Further critical process for development of glass technology of Rubidium bulbs and cells is under development at CSIR-NPL for making the indigenization of space clocks complete.

............. you are doing a great dis-service to the congress by making it a laughing stock in pdf. One would think you are being sarcastic.
