Using the DSST semi-analytical orbit propagator package via the nondywebtools/astrodywebtools open science environment

Laburpena

An initiative within the realm of Space Surveillance Awareness (SSA) is to create an open source software suite that can provide all space actors access to the basic SSA analysis tools needed to operate safely and efficiently in space. These applications include observation compression, orbit propagators, state transition matrix, weighted least squares, improved nonlinear Kaiman filters, realistic process noise, atmosphere density variations, observation data association and observation data simulation which will be rewritten in a modern distributed object-oriented computing environment. It is the intent to make these applications useable via an Internet framework. While the project is being developed, one of the tools considered, the DSST standalone, which is an accurate Semi-Analytical Satellite Theory, can be used through Internet framework Astrody. Tools; Web. This provides an Astrodynamics framework so as to carry out open science in which specialized applications can be integrated, and to encourage scientific collaboration through Internet. This framework, through a user-friendly web interface, allows the user to choose applications, introduce data and select appropriate constraints in an intuitive and easy way, with the help of graphical interface options. After that, the application is executed in real-time and the critical information about program behavior and output (graphical representation of data, statistical analysis or whichever manipulation therein) is shown via the same web interface and can be downloaded to users' computers.
