More info

Although GPS seems to be everywhere, many of its users do not seem to be aware of the fact that it is very easy to interfere with its signals, rendering the timing/positioning service unavailable.

It is therefore quite likely that jamming GPS signals might be used as a weapon, in which case we need alternative ways for determining our position.

The alternative

One of the most reliable alternatives is Astronavigation, impossible to jam, simple and inexpensive tools needed. The drawbacks are that the calculations can be cumbersome and teaching at schools is hardly done anymore.

The solution

In cooperation with Navigation Application, Defence Webshop has developed a computer program that will enable all professional navigators to start using astro-navigation in a very easy way.

Unique

Besides implementing the classical astro-fix, the program will let you calculate a fix using only one star! The advancement of stabilized platforms and handheld computers makes this possible, by supplying the extra data needed for the calculations. You don’t even have to know which star is used!

Usage

Users have a choice of 4 built-in star-almanacs. The classical navigational stars, the bright stars a catalogue of more than 300,000 stars (magnitude>6) and an Infra-red catalogue. Identification is done given an approximate position, time, azimuth and altitude.

The process of obtaining a fix is quick and very well suited for electro-optical platforms, able to track a (bright) star and so have a continuous position fix. By using a stabilized platform, you can shoot stars any moment of the night, not just during twilights.

A submarine with a stabilized periscope, should be able to surface, shoot a star and submerge again in a matter of seconds, so minimizing the risk of being detected.
