Moving objects Databases in space applications

Abstract

Determining moving objects for example spacecraft and visualizing them in defense simulation rapidly and correctly are important research issues in national defense In US military C4ISR systems - Command, Control, Communications, Computers, Intelligence, Surveillance and Reconnaissance- produce objects distance by layers of systems that combine surveillance with weapons control. In military command and control situations the technical requirements of surveillance and reconnaissance involve vast systems and architectures. In this work, moving objects description of geometry over time is concerned in such a military command Moving objects are basically geometries changing over time; hence, this is accomplished in moving object databases which deal with spatial and temporal databases. Spatial databases concern descriptions of geometry in databases and temporal databases address the development of data over time In specific time or time interval, moving object or objects can be queried in moving object databases efficiently. Moving objects capabilities are researched and an example application is described in this work.
