Sattelite alert system

Abstract

A satellite is an object placed into an orbit around a planet. This object may be placed intentionally like artificial satellites or can exist in nature as is moon. Since 1957, thousands of artificial satellites have been launched from Earth and placed into orbit around the Earth. Artificial satellites originate from more than 40 countries and have used the satellite launching capabilities of ten nations. Satellites are used for a large number of purposes. Common types include military and civilian Earth observation satellites, communications satellites, navigation satellites, weather satellites, and research satellites. The military uses include guiding the weapon systems and surveillance via various means and technologies i.e. cartography, oceanography, satellite imagery etc. Satellite Alert System is developed in special context of the military uses of the artificial satellites, however the civil uses cannot be ruled out. The subject application is an active alert system based on tracking the orbits and footprints of hostile country’s satellites which pass over various area of our country at different times. Satellite Alert System is an SGP4 web application which can track satellites and display their respected orbits and show their passes and respective information. The project proposed is an idea to design a digital mechanism which will provide alert notifications to the users at the times of hovering and passage of hostile country’s satellites over them at the present time. Satellite alert system’s significance over the existing alert mechanisms is that it is an efficient, time saving and easy way to get alerts and view the hovering satellites above the atmosphere. The aim is to develop a system that provides a platform for registering and recording available data of hostile Satellites and displaying their details when specified along with the alert of live satellite hovering over the atmosphere with its footprint on a live 3d map rather than reading lengthy and time consuming reports. The idea is to incorporate the system in the Office Automation System’s Portal of Pakistan Armed Forces for timely alerts and respective actions of the concerned departments to address the cause using a more advanced but easier approach and help understand the satellites motion and their surveillance instruments / technologies in a better way.
