A planetarium software that shows a 3D simulation of the night sky
Stellarium renders 3D photo-realistic skies in real time with OpenGL. It displays stars, constellations, planets, nebulae and others things like ground, landscape, atmosphere, etc.
SkyChart is a software to draw chart of the night sky for the amateur astronomer from a bunch of stars and nebulae catalogs. See main web page for full download. This software is part of a full suite for astronomical observation: https://sourceforge.net/projects/ccdciel/ https://sourceforge.net/projects/indistarter/ https://sourceforge.net/projects/eqmodgui/ Requirement: https://sourceforge.net/projects/libpasastro/ See also: https://sourceforge.net/projects/indi/
Real time satellite tracking and orbit prediction
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.
ChronosXP is a planetary hours astrology program for Windows. It runs from the system tray where it displays a glyph corresponding to the current planetary hour. Planetary hours/days can also be viewed for any given time or location.
Satellite tracking software
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 Iridium flares and several other calculations.
Software for planet observation and study
Allow you to visualize any planet aspect at any time. Include extended feature database and texture. Many function are oriented to the observation at the telescope and other to indoor research .
Echoes it's a radio spectral analysis software for RTL-SDR devices,
Echoes it's a radio spectral analysis software for RTL-SDR devices, designed for meteor scattering purposes. RTL-SDR are very cheap Software Defined Radios that uses DVB-T TV tuner dongles based on Realtek's RTL2832U chipset. Echoes doesn't demodulate neither decode any human-made signal. Its main goal is to analyze and record the total power of natural signals and generate screenshots and tabular data (CSV, GNUplot) output in presence of particular peaks in a selected narrow range of frequencies. Since there is no demodulation, there is no provision for audio listening, except for a notify sound when an event has been recorded.
