The GNSS Active Antenna project consists of developing an active antenna for the L1 band (1.565GHz), integrating a low noise amplifier (LNA) powered by 3.3V via picoblade connector. For the selection of components, the study project that appears in [1] was used as a reference.
hardware: Main files of the hardware of the GNSS Active Antenna project.
docs: Technical documentation (including user guide and datasheet)
This project is open-source under the following license: CERN Open Hardware License v2.0 (CERN‑OHL‑P v2).
Releases are published after ensuring that the project itself do not have any major errors and after testing the PCB. Please refer to the documentation for more details.
