For radio amateurs & makers
Any ESP32 LoRa board ($20–30) is all you need. Dozens of compatible boards are supported out of the box.
Flash the firmware directly from your browser, connect to Wi-Fi, and your station starts receiving satellite signals automatically. No RF expertise required.
TinyGS is more than hardware: it is a global community where makers, radio amateurs, and satellite teams exchange knowledge and help each other grow.
For satellite operators
Over 2,200 active stations across the globe mean your satellite is heard every time it passes overhead — anywhere on Earth.
Access a live dashboard showing every packet received, from every station, the moment it happens. No setup required on your end.
Generate independent, fresh TLEs directly from downlinked radio passes. Stop relying on outdated public tracking data—predict your satellite's position with higher precision using custom, community-refined orbital elements.

This week, the TinyGS community celebrated a workshop at EMF Camp that brought 22 new members into the network, while technical discussions dug deep into board performance comparisons between Lilygo and Heltec V3, antenna optimization for different bands, and the nuances of decoding GMSK beacons from SX1262-based satellites. A detailed solar-powered station build also sparked practical advice on making remote setups fully self-sustaining.
This week, the community rallied around the identification and decoding of signals from the newly activated PROVES-Electra satellite, while also tracking the first signals from the freshly deployed FossaSat-2E26. A major milestone arrived with the implementation of FSK AX.100 Mode 5 decoding in the beta firmware, opening up reception for a new class of satellites. Alongside these breakthroughs, members shared practical advice on antenna building, station troubleshooting, and the realities of uplink capabilities, making for a week rich in both discovery and collaboration.
This week saw a collaborative decoding effort that identified a mysterious signal as the newly activated PROVES-Electra satellite, while the community also tackled antenna design challenges and a critical firmware bug affecting FSK satellite tracking. From eggbeater construction debates to impressive station performance upgrades, the channel buzzed with technical problem-solving and shared discoveries.
This week, the TinyGS community tackled a wide range of technical challenges, from configuring new boards and troubleshooting silent stations to exploring the limits of FSK bitrate reception and the impact of atmospheric conditions on signal quality. A deep dive into a failed notch filter experiment, the identification of new LoRa signals from weather balloon radiosondes, and a detailed eggbeater antenna build log made for a particularly rich and instructive edition.
FAQs
tinyGS is an open-source project that allows anyone to set up a low-cost satellite ground station using inexpensive LoRa hardware (like ESP32). By joining the network, you contribute to a global community that provides real-time tracking and data reception for hundreds of satellites and weather probes, making space exploration accessible to everyone.
To get started, you need a supported LoRa board (such as the Heltec WiFi LoRa 32 or TTGO LoRa32), an antenna tuned to the correct frequency (usually 433MHz or 868/915MHz), and a power source. Simply flash the tinyGS firmware onto your board, connect it to your local Wi-Fi, and your station will begin automatically uploading received packets to the network.
While tinyGS is primarily a receive-only (RX) network, some satellite operators occasionally allow for data uplink. However, to participate in these transmissions, you must hold a valid Amateur Radio License to comply with international radio regulations and legal requirements.
By acting as a massive, distributed sensor array. By capturing precise timestamps of signal reception across thousands of global coordinates, the network helps track and verify the orbital position of satellites. This data is vital for predicting satellite paths and avoiding collisions, which is the primary defense against the Kessler Syndrome.
We welcome new missions! Contact us via GitHub or Telegram with your satellite's NORAD ID and modulation parameters (LoRa/FSK). Once integrated, our global network will provide you with a real-time dashboard of your satellite's health and telemetry from across the planet.
The Kessler Syndrome is a theoretical scenario where the density of objects in Low Earth Orbit (LEO) is high enough that a single collision could cause a cascade of debris, making space activities and satellites impossible for generations. tinyGS helps prevent this by providing precise, crowdsourced tracking data.
100% of donations go directly to keeping the network alive and growing.
