Die Frage ist was man mit genauigkeit meint, absolute oder relative genuigkeit. Ich kanns nicht so wirklich beschreiben, ich kopieren mal einen Absatz aus dem Wikipedia Artikel zu Starfire:
http://en.wikipedia.org/wiki/StarFire_(navigation_system)StarFire has developed through two versions. The first, retroactively known as SF1, offered 1-sigma accuracy of about 1 m. Its error was about 15 to 30 cm, meaning that while the displayed position (absolute accuracy) might be off by about 1 m, it could return you to within centimeters of a previously measured spot (relative accuracy). This was enough for the intended role, field surveying. This system was first offered in 1998, and since its replacement the SF1 signal is apparently now offered for free.
The newer system, SF2, was introduced in 2004. It dramatically improves accuracy, with a 1-sigma absolute accuracy of about 4.5 cm. In other words, StarFire will generally leave you within 5 cm of a particular geographical point, and be accurate to under 10 cm around 95% of the time. The relative accuracy is likewise improved, to about 2.5 cm.
