GNSS-SDR

Installation requires managing numerous dependencies across different OSes, with the README listing lengthy steps for Debian, Ubuntu, Fedora, etc., and optional builds like OpenCL or CUDA adding further complexity.

Users must manually tune XML configuration files with deep knowledge of GNSS parameters, such as sampling rates and signal conditioning, which is not intuitive for beginners without signal processing background.

Optimal real-time processing often necessitates running profilers like volk_gnsssdr_profile and manual adjustments for SIMD architectures, rather than being optimized out-of-the-box for all hardware.

While comprehensive, the documentation is extensive and technical, making it difficult to navigate for newcomers without prior experience in SDR or GNSS systems.
