G-FOLD: Fuel Optimal Large Divert Guidance Algorithm

This project implements the G-FOLD algorithm for spacecraft landing trajectory optimization based on:

• Blackmore et al. "Minimum-Landing-Error Powered-Descent Guidance for Mars Landing Using Convex Optimization"
• Neal et al. "Fuel-Optimal Spacecraft Guidance for Landing in Planetary Pits"

G-FOLD is a convex-optimization algorithm that generates the fuel-optimal path to land a spacecraft at the desired location.

Project Structure

This repository is organized into language-specific implementations:

• generator/ - Python package that implements G-FOLD and generates C/C++ code using CVXPYGen
• Additional language implementations will be added in the future

Getting Started

Choose the implementation that best fits your needs:

• For Python usage or code generation, see Generator README

Platform Support

By default, all tools work on Windows, macOS and Linux. However, c++ code generation feature will not support windows, but the bindings that use the generated code will run on windows too.

Development

To set up the development environment:

git clone https://github.com/samutoljamo/g-fold.git
cd g-fold

Then follow the instructions in the specific package directory you want to work with.
