Nova for Windows has become the most popular Windows-based satellite tracking program in the world. In use by NASA, the U.S. Air Force, industry, and thousands of amateur radio operators, Nova sets the standard for excellence. Nova includes realistic maps that are shaded to show vegetation, topography, and ocean bathymetry. Satellite positions are shown with accompanying ground tracks, orbital paths, and star background.

Nova for Windows includes:

Fast, accurate real-time tracking information for an unlimited number of of Earth-orbiting satellites.
Full-color 3-D maps.
Built-in autotracking for turning az/el antennas.
Control antennas with the computer joystick
Super-simple updates of Keplerian Elements... AMSAT or NASA 2-line format.
One-click updating of Keplerian elements via the internet (HTTP & FTP). Can be completely automated for regularly scheduled updates.
Automatic time setting via the internet
Easy-to-use frequency display.
Capture maps and save them to disk, or e-mail to someone else
