Deployment Branches

SkyIntel ships three branches optimised for different environments:

	main	railway	railway-guardrails
Use case	Self-hosting (home server, VPS, Raspberry Pi)	Cloud demo (Railway, Render, Fly.io)	Cloud demo + enhanced chat safety
Flight data	OpenSky Network + ADSB.lol	ADSB.lol global feed	ADSB.lol global feed
Poll strategy	OpenSky global + ADSB.lol military	Single ADSB.lol global call + /v2/mil	Single ADSB.lol global call + /v2/mil
Poll interval	30s	60s	60s
Coverage	Global (OpenSky provides worldwide states)	~7,500+ flights globally (depends on ADSB.lol feeder coverage)	~7,500+ flights globally
Guardrails	System prompt only	System prompt only	System prompt + LLM Guard (BanTopics, Toxicity, InvisibleText)
Extra memory	—	—	~500MB for guardrail models
Military	ADSB.lol /v2/mil	ADSB.lol /v2/mil (same)	ADSB.lol /v2/mil (same)
Satellites/ISS	✅ Same	✅ Same	✅ Same
AI Chat	✅ Same (ADSB.lol live queries)	✅ Same (ADSB.lol live queries)	✅ Same + guardrail scanning
SSE Streaming	✅ Same	✅ Same	✅ Same
Playground	✅ Same	✅ Same	✅ Same + guardrail stats
PyPI	—	✅ pip install skyintel==1.2.0	—

Why multiple branches?

OpenSky Network blocks cloud/datacenter IPs — their API only responds to residential IPs, making it unusable on Railway, Render, and similar platforms. The railway branch replaces OpenSky with ADSB.lol's /v2/point endpoint for global flight data.

The railway-guardrails branch adds LLM Guard scanners for enhanced chat safety, at the cost of ~500MB additional memory (guardrail models are lazy-loaded on first chat request).

ADSB.lol Coverage

ADSB.lol is a crowdsourced network of volunteer ADS-B feeders. Coverage is excellent in North America, Europe, and parts of Asia, but sparse in regions with fewer feeders (e.g. central China, much of Africa, central Russia). This is a data availability limitation of the volunteer feeder network, not something that can be resolved in code.

Which should I use?

• Running locally or on a VPS with a residential IP? → Use main
• Deploying to a cloud platform? → Use railway
• Cloud platform + you want chat guardrails? → Use railway-guardrails (adds ~500MB memory)

SkyIntel is a Python/Starlette backend with a vanilla JS + CesiumJS frontend and no build step. Background pollers fetch flight data from ADSB.lol (global point query + military feed) and satellite TLEs from Celestrak on fixed intervals, storing results in a SQLite database with WAL mode for concurrent reads during writes. A shared service layer (service.py) provides unified query logic consumed by three surfaces: the REST API (globe + detail panel), the MCP server (Claude Desktop / VS Code / Cursor), and the CLI. The LLM gateway (gateway.py) implements a provider-agnostic tool-calling loop via LiteLLM, supporting Claude, OpenAI, and Gemini through a single BYOK interface — with SSE streaming for real-time token delivery. The /playground dashboard provides an observability surface with system metrics sourced from in-memory runtime stats, guardrail monitoring via the optional LLM Guard module (graceful degradation when absent), and LangFuse analytics via REST API reads. All flight classification (military, private, commercial) is performed through pattern-based heuristics in the classifier module, and satellite positions are computed locally via SGP4 propagation using Skyfield.

Architectural Decisions

Decision	Choice	Why
Dual-source data architecture	Globe reads from SQLite (polled), Chat/MCP queries ADSB.lol live	Isolates polling from on-demand queries — avoids API rate limit contention, eliminates single point of failure, ensures globe rendering never competes with user queries
BillboardCollection over Entity API	CesiumJS BillboardCollection + LabelCollection	Entity API crashes at 25k+ objects. BillboardCollection handles 10k+ aircraft smoothly with canvas-based icon caching
SQLite with WAL mode	Single-file DB at ~/.skyintel/skyintel.db	Zero-config, no external dependencies, WAL enables concurrent reads during writes. Sufficient for single-instance tracking workloads
SGP4 propagation over external APIs	Skyfield + sgp4 for satellite/ISS positions	Eliminates external API dependency for position data. TLEs refresh hourly from Celestrak, positions computed locally in real-time with sub-km accuracy
Tool-calling loop with result capping	Default 50 results per tool, total_count always returned	Prevents context window blowout (200k token limit) while giving the LLM accurate counts for reporting
Chat history windowing	Last 6 messages sent to LLM per request	Reduces input tokens per round-trip. Full history stays visible in UI. Clear chat for best results on complex queries
Retry with exponential backoff	3 attempts, 30s/60s waits on rate limit errors	Gracefully handles per-minute token limits on free/low-tier LLM plans instead of failing with raw errors
BYOK security model	API keys in browser localStorage only	Keys never touch the server — sent per-request via POST body, never logged, never persisted server-side
Cesium token masking	Server-side injection via HTML template replacement	Token never exposed in any API response. Injected into index.html at serve time via %%CESIUM_TOKEN%% placeholder
Vanilla JS, no build step	Pure JS + CesiumJS CDN	Zero frontend toolchain complexity. No npm, no webpack, no transpilation. Deploy by copying files
FastMCP dual transport	Streamable HTTP (/mcp) + stdio mode	HTTP for remote/web clients (VS Code, Cursor), stdio for local desktop clients (Claude Desktop)
LiteLLM as LLM gateway	Unified API for Claude, OpenAI, Gemini	Single tool-calling implementation supports all major providers via provider prefixes
LangFuse OTEL integration	Optional observability via LiteLLM callbacks + REST API reads for playground	Zero-code tracing of every LLM call. OTEL ingestion for writes, REST API for dashboard reads. Single host, shared credentials
SSE streaming (simple approach)	Full tool-calling loop runs server-side, only the final LLM response is streamed	Avoids complex partial-stream/tool-call interleaving. Tool status messages sent during processing, final reply streamed token-by-token via Server-Sent Events
Playground observability	In-memory runtime stats + LangFuse REST API + graceful degradation	System metrics from playground_runtime dict (zero DB overhead), guardrail stats from LLM Guard module (ImportError fallback when absent), LangFuse analytics via REST API (returns available: false without keys)
Tool call tracking	In-memory counters in gateway.py	Accurate per-tool heatmap without LangFuse dependency. Tracks actual MCP tool names (not LiteLLM span names). Resets on restart — acceptable for operational monitoring

Guardrails Strategy

SkyIntel uses a layered defense approach for chat safety:

Layer	Mechanism	Cost	Branch
System prompt	LLM instructed to only answer aviation/space topics	Zero — part of every request	All branches
LLM Guard (lightweight)	BanTopics, Toxicity, InvisibleText scanners	~500MB model download on first chat	railway-guardrails only
LLM Guard (full)	Adds PromptInjection, NoRefusal scanners	~1.3GB+ models — higher memory cost	Not shipped (see below)

The heavy PromptInjection scanner (~738MB) and NoRefusal scanner (~827MB) were excluded in favour of system prompt hardening — a deliberate cost/security tradeoff for cloud deployments where memory is billed per GB/hour. The system prompt approach provides effective topic restriction at zero additional cost, while the lightweight scanners add defense-in-depth against invisible text attacks, toxic content, and off-topic abuse.

On the railway-guardrails branch, guardrail scan and block stats are tracked in-memory and surfaced in the /playground dashboard — including per-scanner block counts, block rate, and the 20 most recent blocked queries (anonymised).

Aircraft Classification

Military and private aircraft detection in classifier.py uses pattern-based heuristics:

• Military — Detected via ICAO hex ranges, callsign prefixes, squawk codes, and the ADSB.lol /v2/mil feed
• Private — Detected via known private jet ICAO type codes (e.g. GLF6, C680, CL35, LJ45)

These patterns are maintained for educational purposes and are best-effort, not exhaustive. Contributions to improve classification accuracy are welcome — see src/skyintel/flights/classifier.py for the full ruleset.

Data Sources

Source	Used For	Auth	Polling	Notes
OpenSky Network	Primary flight data for globe (main branch only)	OAuth2 (required)	Every 30s	May block cloud/datacenter IPs. Not used on railway branches
ADSB.lol	Global flight data (railway), on-demand queries (all branches), military feed	None	60s (railway) / On-demand	Crowdsourced — coverage depends on volunteer feeder density
Celestrak	Satellite TLE orbital data	None	Hourly	6 categories: stations, military, weather, gnss, science, starlink
hexdb.io	Aircraft metadata + route lookup	None	Cached (30d/7d)	Can go down intermittently. Errors handled gracefully
Open-Meteo	Weather at any location	None	On-demand	Free, no API key required
Open Notify	ISS crew information	None	On-demand	Only reliable free source for current ISS crew
LangFuse	LLM observability + playground analytics	BYOK keys	OTEL callbacks + REST reads	Free tier. Trace count + tool heatmap surfaced in /playground

⚠️ Why different data for Globe vs Chat? (main branch) The globe reads from SQLite (polled via OpenSky), while chat queries ADSB.lol live. This separation isolates polling from on-demand queries — avoids API rate limit contention and ensures globe rendering never competes with user queries. Flight counts may differ slightly — this is expected and by design.

ℹ️ Note: On railway branches, both globe and chat use ADSB.lol as the data source, but the separation pattern remains: globe reads from SQLite (polled), chat queries the API directly.

Context Management & Rate Limits

Open Sky Intelligence uses a tool-calling architecture where the LLM makes multiple API calls per query. Each call carries the system prompt, tool definitions, and chat history. We've implemented several strategies to manage token usage:

• Chat history windowing — Only the last 6 messages are sent to the LLM per request, reducing input tokens while preserving context. Full history remains visible in the UI.
• Result capping — Tool results default to 50 items with total_count always returned, preventing context window blowout.
• Retry with backoff — Rate limit errors trigger automatic retries (up to 3 attempts, 30s/60s waits).
• Dual system prompts — Web chat uses HTML formatting, CLI uses markdown, keeping responses lean per surface.
• SSE streaming — Final LLM response streamed token-by-token via Server-Sent Events for perceived responsiveness. Tool-calling loop completes server-side before streaming begins.

💡 Tip: Clear chat history before complex queries for best results. Users on free-tier LLM plans should consider lighter models (e.g. claude-haiku-4-20250514, gpt-4o-mini).

⚠️ These are active areas of improvement. Contributions around smarter context summarisation and token counting are especially welcome.

Disclaimer

Open Sky Intelligence is an educational project and technical demonstration showcasing real-time data integration, Model Context Protocol (MCP) tool-calling patterns, and AI-powered geospatial intelligence.

All data is sourced from publicly available open APIs — no classified, proprietary, or restricted data is used. Flight positions come from ADSB.lol and OpenSky Network, satellite TLEs from Celestrak, ISS data from Open Notify, and weather from Open-Meteo.

• Flight and satellite data is provided as-is from third-party sources. Accuracy, completeness, and availability are not guaranteed.
• Military aircraft data is sourced from publicly available ADS-B signals. Not all military aircraft broadcast ADS-B.
• Aircraft classification (military/private/commercial) is based on known patterns and heuristics — see classifier.py for details. This is for educational purposes only.
• ADSB.lol coverage depends on volunteer ADS-B feeder density — some regions (central China, much of Africa, central Russia) have limited coverage.
• ISS crew data is sourced from Open Notify and may not reflect real-time crew changes.
• LLM-generated reports and analyses are AI-assisted and should not be used as sole sources for operational, safety, or security decisions.
• BYOK API keys are stored in browser localStorage only — never persisted server-side. Users are responsible for their own API key security.
