Initial build of Polaris

POLARIS: Python-based Orbital Launch and Asset Regulation Integration Simulator

---

Overview

POLARIS is an open-source astrodynamics and satellite control software developed in Python. Designed for satellite engineers, researchers, and hobbyists, POLARIS provides a suite of tools to simulate and control satellite missions, perform orbital dynamics analysis, and integrate satellite operations into real-world or simulated environments.

Key Features

• Orbital Dynamics Simulation: Accurate simulation of satellite orbits using numerical methods and keplerian mechanics.
• Satellite Control: Tools for station-keeping, attitude control, and orbital adjustments.
• Real-time Visualization: Visualize satellite positions, orbits, and ground tracks with live updates.
• Mission Planning: Optimize satellite missions, including launch trajectory analysis and on-orbit operations.
• Open-source and Extensible: Fully open-source under the MIT license, easily customizable for different use cases.

Quick Start

1. Orbital Dynamics Simulation

POLARIS allows users to simulate satellite orbits. Here’s an example of how to simulate a satellite’s orbit around Earth:

from polaris import OrbitalSimulation

# Initialize a new orbital simulation with parameters
sim = OrbitalSimulation(semi_major_axis=7000, eccentricity=0.01, inclination=28.5)

# Run the simulation
sim.run()

# Plot the orbital trajectory
sim.plot_orbit()

2. Satellite Control (Attitude and Station Keeping)

POLARIS includes a suite of tools to control satellite positioning and execute station-keeping maneuvers:

from polaris import SatelliteControl

# Initialize satellite control for an orbit
control = SatelliteControl(satellite_id='Droid001')

# Perform station-keeping maneuver
control.perform_station_keeping(target_altitude=7000)

# Execute attitude adjustments for imaging
control.adjust_attitude(target_angle=45)

3. Mission Planning and Optimization

Plan and optimize satellite missions, including adjusting orbital parameters for maximum efficiency:

from polaris import MissionPlanner

# Set up a mission planner for a satellite
mission = MissionPlanner(satellite_id='Droid001')

# Optimize the satellite’s orbit for energy efficiency
mission.optimize_orbit()

# Get the optimal launch window
launch_window = mission.calculate_launch_window()
print(f"Optimal Launch Window: {launch_window}")
