Soft Capture of Tumbling Space Objects

Code accompanying the paper "A Convex Formulation of the Soft-Capture Problem". Run examples/scp.jl after installation.

This repository contains:

  • An implementation of the convex trajectory optimization algorithm described in the paper.
  • A dynamics simulator for the maneuver.
  • Full examples with provided geometric models for a chaser and a target satellite in the examples/ directory.
  • A Meshcat-based visualizer.

The algorithm requires a Second-Order Cone Programming solver compatible with Convex.jl. The examples in the paper were run using an academic license of the MOSEK solver (see examples/properties.jl).

Installation

In the Julia REPL

using Pkg
Pkg.activate(".")
# Pkg.add(url="https://github.com/RoboticExplorationLab/SoftCapture")
Pkg.instantiate()
