Universal Navigator is written entirely in the Java language, which means it will run in any operating environment where a Java runtime is available. It has been tested on Red Hat Linux, Sun Solaris, Apple Macintosh OS X, and the Microsoft Windows family of operating systems. Utilizing various high-performance rendering algorthims, including the Java Advanced Imaging API, Universal Navigator is capable of displaying any vector, raster, or gridded datasets. When applied in conjunction with customized datasets processed by Position Integrity, Universal Navigator provides the basis for powerful visual applications supporting real-time situational awareness on the land, sea, and in the skies.
