Updated Apr 17, 2023; Hypatia is a low earth orbit (LEO) satellite network simulation framework. software graphical-user-interface attitude A satellite or artificial satellite is an object intentionally placed into orbit in outer space. A free and easy to use online space orbit simulator that runs in web browsers. After a satellite is detumbled (ECI) frame), and recursive methods to perform tasks like nadir-pointing and attitude maintenance. Updated Dec 18, 2024; MATLAB; echristhuraj / CubeSatDetumblingSimulator. Curate this topic Add this topic to your repo This example shows how to model satellites in orbit, analyze access between the satellites and the ground stations, and visualize the fields of view and ground tracks of the satellites. A research method is presented, including the transformation satellites almanac into YUMA format, the calculation of the satellites coordinates, the compilation of matrices for solving the navigation problem using the least squares method. And it should work given the right initial conditions, for a more complicated set up such as what we are trying now with three bodies. The present annex exposes the complete code developed for the project ’Software design for a Cubesat’s Orbit Simulator’. Matlab is the primary user interface, and is used for building up new navigation models. 36 stars. com/This is a simple little application I coded in MATLAB.
