1. Hardware
Plug an RTL-SDR into a Raspberry Pi and connect a V-Dipole antenna pointed for low Earth orbit passes.
Project SkyGrid Mission Control
The Decentralized Weather Satellite Network.
Transform your Raspberry Pi and RTL-SDR into a node on a global, crowdsourced ground station network. Track Meteor-M, NOAA, and the ISS in real-time.
Backend: degradedTimescaleDB ReadyGo + Next.js
Launch Snapshot
142 active nodes currently reporting
0 satellites tracked in rolling 24h window

How It Works
Three steps from antenna to global map.
2. Software
Run the lightweight Go daemon. It computes TLE windows, wakes SDR capture jobs, and decodes telemetry packets.
3. The Grid
Data is securely POSTed to the TimescaleDB cloud backend and stitched into a global, real-time operations map.
Technical Features
Built for operators and engineers.
Hardware Agnostic
Works with RTL-SDR V3/V4, Airspy, and HackRF front-ends for flexible station builds.
Idempotent API
Redis-backed idempotency guards telemetry ingestion against duplicate packets during flaky uplinks.
Open Source Core
Transparent Go backend and Next.js frontend with explicit contracts and auditable architecture.
Time-Series Storage
Powered by PostgreSQL and TimescaleDB for fast historical queries and mission replay analysis.
