1. Pole star

   A pole star or polar star is a star, preferably bright, nearly aligned with the axis of a rotating astronomical body. Currently, Earth's pole stars are Polaris (Alpha Ursae Minoris), a bright magnitude -2 star aligned approximately with its northern axis that serves as a pre-eminent star in celestial navigation, and a much dimmer magnitude -5.5 star on its southern axis, Polaris Australis (Sigma Octantis). From around 1700 BC until just after 300 AD, Kochab (Beta Ursae Minoris) and Pherkad (Gamma Ursae Minoris) were twin northern pole stars, though neither was as close to the pole as Polaris is now.

1. pole star

   A pole star is a visible star that is approximately aligned with the Earth's axis of rotation, meaning it remains virtually fixed in the sky while other stars appear to rotate around it due to the Earth's rotation. The pole star of the northern hemisphere is Polaris, while the southern hemisphere pole star is Sigma Octantis.

1. Pole star

   A pole star is a visible star, preferably a prominent one, that is approximately aligned with the Earth's axis of rotation; that is, a star whose apparent position is close to one of the celestial poles, and which lies approximately directly overhead when viewed from the Earth's North Pole or South Pole. A similar concept also applies to other planets than the Earth. In practice, the term Pole Star usually refers to Polaris, which is the current northern pole star, also known as the North Star. The south celestial pole currently lacks a bright star like Polaris to mark its position. At present, the naked-eye star nearest to this imaginary point is the faint Sigma Octantis, which is sometimes known as the South Star. While other stars' apparent positions in the sky change throughout the night, as they appear to rotate around the celestial poles, pole stars' apparent positions remain virtually fixed. This makes them especially useful in celestial navigation: they are a dependable indicator of the direction toward the respective geographic pole although not exact; they are virtually fixed, and their angle of elevation can also be used to determine latitude. The identity of the pole stars gradually changes over time because the celestial poles exhibit a slow continuous drift through the star field. The primary reason for this is the precession of the Earth's rotational axis, which causes its orientation to change over time. If the stars were fixed in space, precession would cause the celestial poles to trace out imaginary circles on the celestial sphere approximately once every 26,000 years, passing close to different stars at different times. However, the stars themselves also exhibit proper motion, and this motion is another cause of the apparent drift of pole stars.

1. Pole Star

   Making up for the limitations and weakness of GPS Satellite navigation signals (GPS signals as well as future Gallileo signals) cannot be used for location inside buildings, parking lots or underground, where signals are weak or blocked. Yet the indoor and outdoor location requirements of both consumers (via smart phones) and businesses are fast-growing in particular in terms of security as well as work method control and optimization. To meet increasing demand for indoor location solutions, Pole Star has designed and developed the NAO Campus® indoor location technology for consumer and professional applications.Since April 2008, NAO Campus® has been implemented all over the world (Europe, North America and Asia) in all types of buildings and environments including malls, museums, train stations, airports, underground parking lots, hospitals, industrial sites, and office buildings. Today, Pole Star is a market leader in the field. With their unique expertise and proven solution, Pole Star has paved the way for new applications and is equipped to satisfy tomorrow's requirements.
