USING THE SECOD LAW OF COSINE THE WIRELESS MOBILE-STATION POSITION'S ESTIMATION METHOD

摘要

A wireless mobile-station positions estimation method using the second law of cosine is provided to estimate location quickly with a simple program without drawing figures. P is angle to MS for obtaining based on a line between BS1 and BS4. T is sum of 1 and p. The angle T is a maximum angle between BS. An isosceles triangle is drawn depends on the condition of angle T, so the angle between 1 and P are easily obtained by the second law of cosine.
