About Me

Abolfazl Shirazi

I am a Postdoctoral Researcher at BCAM - Basque Center for Applied Mathematics. In 2016, I was awarded the La Caixa Fellowship Grant for my doctoral studies and in 2021 I obtained my Ph.D. degree with “Sobresaliente Cum Laude” distinction award from the University of the Basque Country UPV/EHU. My research interests are Astrodynamics and Machine Learning and my activities mainly involve spacecraft trajectory optimization, evolutionary computations, space dynamics and control, numerical simulation, orbital mechanics, meta-heuristics, and software development for space simulation.

My research interests are in the field of space engineering including orbital mechanics, attitude control, spacecraft dynamics, interplanetary trajectories and optimal control. In my Ph.D program, I am working on the development of optimization algorithms for spacecraft trajectory design and optimization.

About Homa

Overview

HOMA is a space orbit simulator developed by Abolfazl Shirazi. It is an online tool that analyzes the space orbits and generates 3D visualization of the space trajectory along with ground track and numerical results.

History

The current online tool was originally a MATLAB-based tool, developed in 2011 as a 3D environment framework for understanding orbital elements. The website was launched on July 2014, based on searching in a database of results which have been simulated by the MATLAB code. Until October 2016, the online simulator had limited option in specifying orbital elements. In late 2016, the work for turning the MATLAB code into a WebGL tool started. In October 2017, the upgraded version of HOMA with unlimited simulation was launched successfully.

Simulation

The space orbit simulator displays satellite orbits and generates usable data associated with space trajectories. Designed to fill a need for affordable, user-friendly online tool, HOMA is an academic educational tool intended for engineering, physics, and astronomy students, as well as professors of introductory orbital mechanics. It can also be used for quick visualization and analysis of satellite orbits. The tool can generate a satellite ground track or trajectory with high quality graphics, allowing the user to modify and visualize various orbits, and convert Keplerian orbital elements to position and velocity vectors. In addition, given the orbital elements, HOMA computes the anomalies including mean anomaly and eccentric anomaly and their variations.
