PreviSat is a satellite tracking software for observing purposes. Very easy to use, it shows positions of artificial satellites in real-time or manual mode. PreviSat is able to make predictions of their passes, predictions of MetOp and COSMO-SkyMed flares, transits of all satellites, predictions of Starlink satellites passes and several other calculations.

Gpredict is a real-time satellite tracking and orbit prediction application. Gpredict can track an unlimited number of satellites and display the data in tables and various graphical view.

finds exact gain, directivity and input impedance of Yagi or log-periodic antennas (planar symmetric array of cylindrical dipoles, many driven elements) for a range of specified frequencies, integrates 2D for segments on the same element, moment method

Antenna, a free and open-source dvb-t (terrestrial digital tv) tuner for linux desktops. Antenna is a full featured tool to see what's going on in the sky. It enables you to scan, watch and record television, radio and services broadcasted on air.

Two (2) dimensional evaluation at PN point of conflict/confusion calculated using a single vector perpendicular to cell antenna face (antenna bore). Output created in pdf file.

RFOPTI provides the structure for calculating path loss at a drive data point. A two dimensional calculation provides antenna gain at drive data point angle in an output file.

WS1281DEC is a portable Win32 application that extract and display the data transmitted by WS1281 weather station external sensor, using the sound device of a PC computer and some additional hardware and software. Hardware requirements are RTL-SDR dongle (e4000 or R820T tuner ), external antenna, and a PC. As additional software, it is necessary to have SDR Sharp and Virtual Audio Cable. The whole system was tested on Windows 7 64 bit OS

NF2FF is a MATLAB script, which implements a near field to far field transformation for near field antenna measurement setups.

Software Defined Radio Transceiver project is written in Python while using GNU Radio and USRP. The goal is to create a software HF transceiver with various modes. Go here for more info: http://apps.sourceforge.net/mediawiki/sdr/index.php?title=Main_Page

The objective of this project is to implement a fully open source software package to design X-Band antennas similar to the ones developed by NASA fot Space Technology 5 Mission.

Enhanced Machine Controller-based Antenna Range (EMCAR) EMCAR employs LinuxCNC based machine control (linuxcnc.org) coupled with open source software to implement a measurement system for antenna radiation pattern data (i.e. an antenna range).

Antenna Radiation Diagram Plotter - Polar plots of measured EM emission, with a proper radial axis scaling and span. Three source files (plain text) can be loaded and plotted at the same time. Export to file or clipboard.

K-Track is an graphical satellite prediction Program that runs under KDE. It's really accurate as it calculates using the NORAD SGP4/SDP4 Models. It Controls your Rig for doppler compensation / antenna pointing

FDTD Antenna Simulator is a complete software package for antenna analysis and design using the FDTD method.
