The GNSS Toolkit (GNSSTk) is an open-source (LGPL) project sponsored by the Space and Geophysics Laboratory (SGL), part of the Applied Research Laboratories (ARL) at The University of Texas at Austin.
The primary goals of the GNSSTk project are to:
- provide applications for use by the GNSS and satellite navigation community.
- provide a core library to facilitate the development of GNSS applications.

All sort of software which has to do with electronics.

This repository contains tools for developing of electronic circuits and firmware for microcontrollers.

You can find here tools for devices too small (in whatever dimension) to run a Linux kernel.

Discord is an all-in-one voice and text chat for gamers that's free (beer), secure, and works on both your desktop and phone.
This is a modified version of Discord to remove the patent encumbered ffmpeg and swap with electron's pre-built non-patent ffmpeg lib.

CHIRP is a free, open-source tool for programming your amateur radio. It supports a large number of manufacturers and models, as well as provides a way to interface with multiple data sources and formats.

flaa is an interface application for RigExpert antenna analyzers.

GNU Radio is a collection of software that when combined with minimal
hardware, allows the construction of radios where the actual waveforms
transmitted and received are defined by software. What this means is
that it turns the digital modulation schemes used in today's high
performance wireless devices into software problems.

Gqrx is an experimental software defined radio receiver implemented using
GNU Radio and the Qt GUI toolkit. Currently it works on Linux and Mac and it
can use the Funcube Dongle, RTL2832U-based DVB-T dongles, OsmoSDR devices and
USRP devices as input source.

gr-funcube is an linux oot-module for gnuradio to implement a FUNcube Dongle and a FUNcube Dongle PRO+ source. It utodetects the correct soundcard from /proc/asound/cards. This idea was taken from the osmosdr drivers. To control the device, the hidraw code of the HID API is used.

The goal of the UHD is to provide a host driver and API for current and future Ettus Research products. Users will be able to use the UHD driver standalone or with 3rd party applications.

Here are openSUSE packages by Wojciech Kazubski. Main fields of interest are electonics, ham radio and possibly astronomy.
