Scarabaeus Roadmap#

Last revised on 2026 MAY 27 by G. Fereoli.

Performance Improvements#

  • Move performance-critical components from Python to Rust

  • Improve propagation, filtering, and Monte Carlo scalability

Measurement and Filtering V&V#

  • Document V&V of measurement models (DSN range, Doppler, range and range-rate) and analytical partial derivatives

  • Compare covariance analysis results to state-of-the-art OD software

  • Document data processing and filter results for multiple missions

Real Measurement Model Enhancements#

  • Extend geocentric-frame support so real radiometric models operate correctly inside Earth’s sphere of influence; implement partial derivatives of tropospheric and ionospheric media corrections to enable atmospheric parameter estimation alongside the spacecraft state

Finite-Burn Targeting#

  • Use Scarabaeus as a local targeting and optimization framework

Delta-DOR Implementation#

  • Full Delta-DOR measurement modeling and estimation support

Terrain Relative Navigation#

Map-Based#

  • Landmark and catalogue-based navigation

Map-Free#

  • Visual odometry and feature tracking

Proximity Operations#

  • Small-body geophysical estimation

  • Gravity and rotational-state recovery

  • Reference-frame switching and local-frame operations

Multi-Arc Filtering#

Binary Asteroid Simulator#

  • General-use binary asteroid simulation environment

  • Hera mission operational scenarios
