| | |
| Receiving weather images directly from space using simple equipment.
| |
| | |
| == Active Satellites ==
| |
| | |
| - NOAA 15 - 137.6200 MHz
| |
| - NOAA 18 - 137.9125 MHz
| |
| - NOAA 19 - 137.1000 MHz
| |
| | |
| Transmitting APT (Automatic Picture Transmission) as they pass overhead.
| |
| | |
| == Reception Basics ==
| |
| | |
| === Minimal Setup ===
| |
| | |
| - RTL-SDR dongle ($30)
| |
| - V-dipole or QFH antenna
| |
| - Computer running SDR#
| |
| - WXtoImg or noaa-apt for decoding
| |
| | |
| === Better Setup ===
| |
| | |
| - LNA (low noise amplifier)
| |
| - QFH or turnstile antenna
| |
| - Raspberry Pi for automated captures
| |
| | |
| == The Magic ==
| |
| | |
| These satellites broadcast continuously. When one passes overhead (4-6 good passes daily), you can receive live weather imagery showing hundreds of miles of Earth. No license needed. No subscription. Just you and a satellite.
| |
| | |
| == Signal Characteristics ==
| |
| | |
| - FM modulated
| |
| - 2400 Hz subcarrier
| |
| - Transmits during entire pass
| |
| - Strongest when directly overhead
| |
| - 10-15 minute passes
| |
| | |
| == Forestpunk Applications ==
| |
| | |
| - Monitor weather systems approaching your area
| |
| - Track forest fire smoke plumes
| |
| - Observe seasonal changes from space
| |
| - Complete off-grid weather intelligence
| |
| | |
| == Current Projects ==
| |
| | |
| - Building weatherproof permanent station
| |
| - Automated capture and processing pipeline
| |
| - Integration with local mesh network
| |
| - Correlating images with ground observations
| |
| | |
| == Next Steps ==
| |
| | |
| - METEOR M2 reception (digital, higher resolution)
| |
| - GOES geostationary reception (requires dish)
| |
| - ISS SSTV events
