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 Stop relying on outdated public tracking data—predict your satellite's position with higher precision using custom, community-refined orbital elements.
Step 1: Join the community

TinyGS operators dug into a puzzling drop in packet reception, tracing causes from cable integrity to Tianqi interference and autotune settings. A newcomer's untrimmed quarter-wave build surprised everyone with 3,312 km reception, while the community shared updates on upcoming LoRa missions and helped new stations get online. From coax loss debates to kiosk display ideas, it was a week of practical problem-solving and shared discovery.
This week TinyGS welcomed a genuinely new way to run a station — a pure-Python LoRa decoder paired with an SDR ground station client — while Brazil's first educational station went live at a school in São Paulo. Between a deep community investigation into why LNAs keep dying, a long debate on circular versus linear antennas and the Tianqi satellites that refuse to be heard, and a bug hunt in the website's telemetry decoding, it was a week that mixed fresh hardware ideas with serious troubleshooting.
Front-end filtering took centre stage this week as the community weighed SAW filters against Chebyshev high-pass alternatives for 433 MHz reception, and compared Lilygo boards for tracking low-band satellites around 137 MHz. Meanwhile the satellites from the recent Norwegian ISAR launch began reporting in, with FramSat-1 already delivering telemetry on every pass, while a station struggling with CRC errors got practical noise-floor and antenna advice. From group-delay curves to a brand-new station coming online with a little help from friends, it was a week that balanced hard RF engineering with the community spirit of getting newcomers on the air.
This week the TinyGS community compared antenna designs for 137 MHz reception, untangled a few frequency mysteries around ET-001D and the silent ConnectaIoT satellites, and followed a student balloon mission preparing to launch from Singapore. Antenna builders weighed the double-cross against Lindenblad and J-pole designs, while newcomers received hands-on advice for their first Heltec V3 stations. It was a week of practical troubleshooting, shared builds, and a good look at how the network keeps growing.
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.
