Current Limitations & Scope

This document outlines the current scope, known gaps, and limitations of Constellation Hub's MVP release.

Project Scope

Constellation Hub is designed as a unified control plane for satellite constellation operations. The current MVP focuses on:

✅ Core Operations: Fleet visualization, pass scheduling, ground network management
✅ AI-Assisted Planning: Intelligent schedule optimization and operational assistance
✅ Production-Ready Foundation: Authentication, observability, database migrations, TLE ingestion
✅ Modern Stack: Cloud-native architecture, API-first design, containerized deployment

Current Limitations (MVP)

1. Multi-Tenancy & Isolation

Current State: Single-tenant or trusted environment only

  • ✅ Supports one organization/constellation at a time
  • ✅ User roles (viewer, operator, admin) within single tenant
  • ❌ No hard multi-tenant data isolation
  • ❌ No tenant-specific resource limits or quotas

Use Cases:

  • ✅ Single constellation operator (startup, research mission)
  • ✅ Internal tools for a single organization
  • ⚠️ Multi-customer SaaS (requires additional isolation)

Tier 3 Roadmap: Add tenant isolation, per-tenant databases, resource quotas

2. AI Safety & Human-in-the-Loop

Current State: AI agents are assistive tools, not autonomous operators

  • ✅ AI provides schedule optimization recommendations
  • ✅ AI analyzes operational events and suggests actions
  • ✅ Human approval required before executing AI recommendations
  • ❌ AI does not execute commands autonomously

Guardrails:

  • AI "apply" actions restricted to operator role or higher
  • All AI actions logged for audit
  • Operators review AI proposals before execution

Philosophy: AI augments human expertise but does not replace operator judgment.

3. Security & Compliance Posture

Current State: Not certified for classified or high-security environments

  • ✅ JWT authentication with bcrypt password hashing
  • ✅ Role-based access control (RBAC)
  • ✅ Structured logging with request tracing
  • ✅ Health probes for operational monitoring
  • ❌ Not FIPS 140-2/3 certified
  • ❌ Not cleared for classified data (SECRET/TS)
  • ❌ No multi-factor authentication (MFA) yet
  • ❌ No hardware security module (HSM) integration

Use Cases:

  • ✅ Commercial satellite operations (unclassified data)
  • ✅ Research and academic missions
  • ✅ Internal dev/test environments
  • ⚠️ Government classified missions (requires hardening review)
  • ⚠️ Financial or healthcare data (requires compliance audit)

Deployment Guidance:

  • For classified environments: conduct security review, add controls (MFA, HSM, network isolation)
  • For regulated industries: perform compliance assessment (GDPR, HIPAA, etc.)
  • For production: change default secrets, enable audit logging, restrict network access

4. Simulation & Emulation

Current State: Live operations logic and visualization; simulation not yet implemented

  • ✅ Real-time satellite position visualization (via TLE propagation)
  • ✅ Pass prediction and scheduling for live constellations
  • ❌ No physics-based orbital simulator
  • ❌ No constellation design/simulation mode
  • ❌ No "what-if" scenario analysis for future constellations

Use Cases:

  • ✅ Operating existing satellites in orbit
  • ✅ Planning passes for deployed constellations
  • ⚠️ Pre-launch constellation design (requires simulation)
  • ⚠️ Trade studies for new missions (requires modeling)

Tier 3+ Roadmap: Add simulation mode for constellation design and trade studies

5. Ground Network Capabilities

Current State: Supports ground station management and pass scheduling

  • ✅ Multi-ground-station network modeling
  • ✅ Pass prediction with elevation constraints
  • ✅ Schedule generation and conflict resolution
  • ⚠️ Limited antenna pattern modeling (assumes omnidirectional)
  • ❌ No real-time antenna pointing control
  • ❌ No signal link budget calculations
  • ❌ No weather/atmospheric effects modeling

Future Enhancements:

  • Antenna pointing automation
  • Link budget and margin analysis
  • Weather-aware scheduling
  • Integration with commercial GSaaS providers (AWS Ground Station, Azure Orbital, etc.)

6. Data Routing & ISL Modeling

Current State: Basic inter-satellite link (ISL) routing logic

  • ✅ Graph-based routing of data through constellation
  • ✅ Shortest-path and capacity-aware algorithms
  • ⚠️ Simplified link capacity models
  • ❌ No optical ISL power/pointing constraints
  • ❌ No realistic RF link budgets for ISLs
  • ❌ No dynamic topology updates as satellites move

Use Cases:

  • ✅ Logical data routing for small constellations
  • ⚠️ High-fidelity ISL performance modeling (requires enhancement)

7. Scalability & Performance

Current State: Designed for small-to-medium constellations (10–500 satellites)

  • ✅ Handles 10–100 satellites efficiently
  • ✅ Horizontal scaling via microservices
  • ⚠️ Not yet tested with 1,000+ satellites
  • ⚠️ Globe visualization may degrade with very large constellations

Performance Notes:

  • Pass computation can be CPU-intensive for large constellations
  • Consider caching or pre-computation for mega-constellations
  • Frontend globe rendering limited by browser WebGL performance

8. External Integrations

Current State: Limited integrations; extensible via APIs

Available:

  • ✅ CelesTrak TLE ingestion
  • ✅ REST APIs for all services
  • ✅ Prometheus metrics export

Not Yet Integrated:

  • ❌ Space-Track.org (TLE source, requires credentials)
  • ❌ AWS Ground Station
  • ❌ Azure Orbital
  • ❌ Satellite command and control (C2) systems
  • ❌ Mission planning tools (STK, GMAT, etc.)

Integration Path: Use REST APIs to connect Constellation Hub with external systems

Development & Testing Gaps

Testing Coverage

  • ✅ Unit tests for backend services
  • ✅ Integration tests for API endpoints
  • ⚠️ Limited end-to-end (E2E) tests
  • ❌ No load/stress testing results published
  • ❌ No chaos engineering or resilience testing

CI/CD Maturity

  • ✅ Automated linting and tests on every commit
  • ✅ Docker image builds
  • ⚠️ No automated deployment pipelines to staging/production
  • ❌ No blue/green or canary deployment strategies
  • ❌ No automated rollback mechanisms

Deployment & Operations Gaps

Infrastructure as Code

  • ✅ Docker Compose for local dev
  • ⚠️ No Kubernetes deployment manifests yet
  • ❌ No Terraform or Pulumi infrastructure definitions
  • ❌ No Helm charts for easy K8s deployment

Observability

  • ✅ Structured logging (JSON)
  • ✅ Prometheus metrics endpoints
  • ✅ Health and readiness probes
  • ⚠️ No pre-built Grafana dashboards
  • ❌ No distributed tracing (OpenTelemetry, Jaeger)
  • ❌ No alerting rules defined

Backup & Disaster Recovery

  • ❌ No automated database backup solution
  • ❌ No disaster recovery (DR) plan documented
  • ❌ No multi-region deployment guidance

Comparison with Commercial Alternatives

Constellation Hub is an open-core alternative to proprietary satellite operations platforms.

Feature Constellation Hub (MVP) Commercial Platforms
Licensing Open-source (Apache 2.0) Proprietary, licensed per seat
Cost Free to use High licensing fees
Customization Fully customizable Limited or none
Vendor Lock-In None High
AI-Assisted Ops ✅ Built-in ❌ Bolt-on or none
Multi-Tenant SaaS ❌ Not yet ✅ Often yes
Classified Support ⚠️ Requires review ✅ Some vendors certified
Simulation ❌ Not yet ✅ Often included
GSaaS Integration ❌ Not yet ✅ AWS, Azure, etc.

When to Choose Constellation Hub:

  • You want full control and customization
  • You need to avoid vendor lock-in
  • You're operating a small-to-medium constellation (10–500 satellites)
  • You value open-source transparency and community-driven development

When Commercial Tools May Be Better:

  • You need pre-certified solutions for classified environments
  • You require comprehensive simulation/modeling capabilities
  • You need extensive GSaaS integrations out-of-the-box
  • You prefer vendor support and SLAs

Roadmap to Address Limitations
