Introduction
Space surveillance provides information on what is orbiting Earth. The smallest object that can be tracked is about 4 inches (10 cm) in diameter. Space surveillance provides essential information to the operators of space systems, helps to determine the capabilities of potential adversaries, predicts the orbits of objects in space to include warning of potential collisions, provides warning of an attack on a U.S. space system, and predicts space object reentry impact points.The smallest object that c ....etc

ABSTRACT
Global Positioning System (GPS) is the only system today able to show ones own position on the earth any time in any weather, anywhere. This paper addresses this satellite based navigation system at length. The different segments of GPS viz. space segment, control segment, user segment are discussed. In addition, how this amazing ....etc

A pulse detonation engine is an unsteady propulsive device in which the combustion chamber is periodically filled with a reactive gas mixture, a detonation is initiated, the detonation propagates through the chamber, and the product gases are exhausted. The high pressures and resultant momentum flux out of the chamber generate thrust.

Quasi-steady thrust levels can be achieved by repeating this cycle at relatively high frequency and/or using more than one combustion chamber operating out of phase.A pulse ....etc

Global Positioning System
Global Positioning System is an System to Identify the Position on Globe through a Network Of Satellites.
The Global Positioning System (GPS) is a U.S. space-based global navigation satellite system. It provides reliable positioning, navigation, and timing services to worldwide users. The Space, Control and User are the three segments of this . The User Segment is composed of hundreds of thousands of U.S. and allied military users of the secure GPS Precise Positioning Service. The Space Segment is composed of 24 ....etc

INTRODUCTION

The history of antimatter begins with a young physicist named Paul A.M.Dirac (1902-1984) and the strange implications of a mathematical equation. This British physicist formulated a theory for the motion of the electrons in electric and magnetic fields. Such theories had been formulated before, but what was unique about Dirac’s was that his included the effects of Einstein’s Special Theory of Relativity. This theory was formulated by him in 1928.Mean while he wrote down an equation, which combined quantum theory and s ....etc

Have u ever been lost and wished there was an easy way to find out which way u needed to go? How about finding yourself out hiking and then not knowing how to get back to your camp or car? Ever been flying and wanted to know the nearest airport?

Our ancestors had to go to pretty extreme measures to keep from getting lost. They erected monumental landmarks, laboriously drafted detailed maps and learned to read the stars in the night sky.

GPS is a satellite based radio navigation system which provides continuous, all weather, worldwide nav ....etc
