A tutorial on how to flash Meshtastic with the Fancy UI firmware on the LILYGO T-Deck Plus, including detailed steps and troubleshooting tips.
T-Deck Plus, flashed 2.5.4.8d288d5, then went into configuration set GPS pins
- RX 44
- TX 43
- enabled GPS
The project involves a software-defined GPS receiver using the legacy C/A code to produce clock bias and location estimates. It can run from pre-recorded sample files or an RTL-SDR with a web-based dashboard for visualization. The project is written in Python, utilizing libraries like aiohttp, NumPy, Pydantic, and pyrtlsdr.
The article describes a project where someone developed a software-defined GPS receiver from scratch using Python and an RTL-SDR dongle. The project tackles the 'coarse' positioning capability of GPS, achieving location resolution within 24 seconds from a cold start. The article highlights the project's accessibility and potential as a starting point for further exploration of GPS technology.
T-Beam Meshtastic is a wireless module with ESP32, LoRa, GPS, WiFi, and Bluetooth capabilities. It features a 0.96-inch OLED display and supports various frequency bands including 433/868/915/923Mhz.
Google researchers demonstrated the ability to use GPS signal measurements from millions of anonymous Android mobile devices to map the ionosphere with high accuracy, potentially improving GPS navigation worldwide.
