Various software packages are available related to meteors and meteor data processing.
The Radiant software calculates density distributions of meteor radiants. The input procedures interpret meteor co-ordinate data in the PosDat and FIDAC formats. The user should have some basic knowledge of creating dBase files. The density distributions are gnomonically projected, thus simplifying the calculating procedures. For most radiant searches the investigated area is small enough (less than twenty degrees across) that the scale changes over this "gnomonic chart" can be neglected. Radiant knows three methods of radiant determinations: backward tracings, intersection counts and probability distributions.
MetRec (Meteor Recognizer) is a software package for the automatic detection and analysis of video meteors. It can be used both to inspect video tapes offline, and to do online recognition for an automatic video meteor camera.
QRicht provides you with all required information to aim your cameras for double-station observations based on the observation time, the geographic coordinates of 2, 3 or 4 stations, the height in the atmosphere of the aiming point and the geographic coordinates of the aiming point in the atmosphere.
VISDAT is a system for recording and evaluating visual meteor observations. The first version was developed in 1991 by Thomas Rattei and later by Janko F. Richter (both Astroclub Radebeul e.V. Germany).
The Astro Record program is aimed at making position measurements of celestial objects, especially meteors, and performing the associate astrometric calculations. For this purpose screen coordinates of the object and of a number of reference stars can be measured, equatorial coordinates of the reference stars can be looked up, and the results of the astrometric calculations can be analyzed regarding wrong star identifications and plate defects.
A new version of MetShow is running in all contemporary windows operating systems. The program can help meteor observers to prepare and evaluate their observations. MetShow is based on the IMO Working List of Meteor Showers. It can work either with the new list according to the 2011 calendar or with the older list from 2006. The software produces the following information for the active showers on a given date:
This program permits the calculation of the performance of Yagi antennas. It runs under MS-DOS.
This is a program of radio amateurs for the prediction of meteor scatter. We don't know its reliability, and there is no documentation in the package. It runs under MS-DOS

EZNEC and EZNEC+ are powerful but very easy-to-use programs for modeling and analyzing nearly any kind of antenna in its actual operating environment. EZNEC plots azimuth and elevation patterns; tells you gain, feedpoint impedance, SWR, and current distribution; finds and reports beamwidth, 3-dB pattern points, f/b ratio, takeoff angle, sidelobe characteristics; and more. All information, including patterns, can be displayed on screen or printed on any Windows compatible printer. Can be found at http://www.eznec.com/.
