Astrodynamics
Two-body and J2 propagation, eclipse analysis, coordinate transforms, ground access, external comparison adapters and analytical benchmarks.
Capabilities
Space engineering, data systems and operational assurance.
OpenSat Mission Lab grew from a two-body orbital demonstrator into a broad mission-engineering portfolio. Every capability remains inspectable and runnable on a home PC.
Payload operations
Camera footprint, target visibility, priority-aware imaging, data generation, storage, compression, cloud filtering and scheduling.
Electrical power
Solar generation, battery integration, mode-specific loads, eclipse discharge, safe-mode entry and hysteretic recovery.
Communications
S-band link budgets, C/N₀ and Eb/N₀, adaptive data rates, pass capacity and actual onboard-storage depletion.
ADCS
Quaternion kinematics, sensor noise, detumbling, pointing modes, wheel momentum and magnetic unloading.
Flight software
Mode logic, commands, telemetry, CRC packets, watchdog reset, limit monitoring, deterministic fault injection and recovery.
Earth observation
GeoTIFF ingestion, spectral indices, ground-truth metrics, temporal optical/SAR fusion and flood progression.
Onboard autonomy
Explainable event scoring, resource-aware keep/discard decisions, target reprioritization and autonomous task planning.
Constellation safety
Walker-style formations, crosslinks, shared ground resources, conjunction screening, maneuver trades and replanning.
Service platform
REST/STAC APIs, workers, object storage, database catalogues, backups, role controls and deployment assets.
Security & resilience
Zero-trust controls, SBOMs, signed evidence, observability, chaos exercises, active-active routing and governance.
Safety assurance
Signed approvals, dual control, exact command authorization, workflow migration, replay and finite-state checking.
Release evolution
From v0.1 to v3.1
Each milestone added one coherent engineering layer rather than disconnected demonstrations.
v0.1–0.7
Orbit propagation, contacts, payload, power, communications, ADCS and flight software.
Spacecraft corev0.8–1.4
Mission control, reliability, HIL, constellations, conjunction screening and replanning.
Operationsv1.5–1.9
Onboard autonomy, calibrated EO imagery, optical/SAR fusion and geospatial data cubes.
Earth datav2.0–2.9
Services, object storage, identity, governance, zero trust, supply chain and multi-region systems.
Platformv3.0–3.1
Policy-governed orchestration, human approval, compensation, signatures and safety invariants.
