Description

The simulation showcases a satellite orbiting Earth, capturing data for use in various computational algorithms. This simulation can be utilized for research and development in fields related to computer vision, machine learning, and 3D graphics.

Scale and Measurements

The simulation uses a 1:10000 scale model. The key measurements are as follows:

Earth Diameter: 12756 km → 127.56 m in simulation
Atmosphere Thickness: 100 km → 1 cm in simulation
- Total Diameter with Atmosphere: 12856 km → 128.56 m
Satellite Size: 10 m → 0.001 m in simulation
Low Earth Orbit (LEO): 500 km above Earth surface → 50 m in simulation

The satellite orbits approximately 50 m + (127.56 m / 2) ≈ 113.78 m from the Earth's center in the simulation.

Installation

Clone the repository:

git clone https://github.com/yourusername/satellite-orbit-simulation.git
cd satellite-orbit-simulation

Install Blender 4.0 or higher: Follow the official Blender installation guide. set folder's name and hierarchy as described in Folder Structure section.
Open Blender and load the scene:

Open Blender, navigate to the Scene folder, and open satellite_earth_model_for_3DGS.blend.
Generate Simulation:
- Adjust settings as needed (e.g., resolution, rendering details, animation settings) or click render->render animation to generate data with default settings.
- Alternatively, run the script orbit_around_satellite.py to automate the process.

Requirement

Nvidia GPU (any 3060 or higher will do)
basic knowledge of blender
