navigator software: brief history

Navigator software project started in 1992. The first version was for DOS and HP LX palmtop computers. In 96 I started this website, after translating the Navigator to English and Windows. In 97 this web site started serving the navigation community with tutorials and calculation services (on line nautical almanac and star finder applications).

Around 2008 I wrote VRTool, used by the virtual regatta community. Now writing navigation software for mobile devices (Android/ iOS / Windows).
