Future Work - Project Roadmap

Overview

This document outlines planned enhancements and future development areas for the Orbital Mechanics Simulation project.

Immediate Priorities

More Accurate Integration Methods

Current: RK4 (Runge-Kutta 4th order) integration Proposed: Newton-Raphson propagation for higher precision

Benefits:

• Improved accuracy for long-term orbit predictions
• Better handling of near-parabolic trajectories
• Reduced numerical drift in N-body systems

Implementation Considerations:

• May require adaptive timestep sizing
• More complex than RK4
• Trade-off between accuracy and performance

Reference Frame Switching

Current: Fixed global/local coordinate frames per body type Proposed: Dynamic reference frame selection based on orbital regime

Use Cases:

• Spacecraft transitioning between planetary SOIs
• Interplanetary trajectories needing optimal precision
• Multi-body perturbation modeling

Benefits:

• Optimal numerical precision for all orbit types
• Automatic frame selection based on physics state
• Better simulation stability during SOI transitions

Mid-Term Enhancements

SOI Transition Frame Transformations (Phase 3)

Status: Partially implemented (SOI detection complete) Missing: Proper coordinate transformations during SOI crossings

Requirements:

• Convert position/velocity between frames during transition
• Preserve orbital elements across frame boundaries
• Handle momentum and energy conservation
• Implement smooth interpolation to avoid discontinuities

Implementation:

• Define transformation matrices for frame changes
• Implement hysteresis to prevent oscillation
• Add validation tests for energy/momentum conservation
• Consider relative velocity of parent bodies
