IPS can eventually contribute to the formation of social networking

In the rapid development of technology, the rapid urban construction, the the Blind naturally growing number of. As the saying goes "The road in the mouth" seems to be no longer applicable, because to come up with a computer or smart phone, GPS positioning, to ask the way becomes easier. Therefore, GPS has become the essential thing of people traveling, but powerful as GPS is also out of reach, it is indoor.

    So now the indoor positioning system (IPS) has naturally become the next important goal of science and technology researchers.

    Has been very popular portable navigation devices to automatically drive a car well-respected, and even cruise missile guidance, the realization of all these applications, technology, thanks to the U.S. Global Positioning System (GPS) and its Russian partners - - Gloria NASDAQ Global Navigation Satellite System (GLONASS). However, they have to fly in the ointment: one can not be in the room; Second, they can only be hovering in the two-dimensional world.

    Today, more and more obvious inconvenience caused by these constraints. After all, we are using is extremely weak satellite signals through the twenty thousand kilometers long journey through the concrete and other solid obstacles, in fact, not very "to force": In fact, the GPS signal is detected on Earth difficulty the faint light of 25 watt light bulb to search more than twenty thousand kilometers. During the detection of elevation changes, the situation will become more complex. GPS and GLONASS are able to roughly measure the altitude, but the data obtained in normal circumstances is more rough car dvd and car gps and limited accuracy (about 10-25 m range).

    Of course, despite the existence of various defects, based on GPS satellite navigation system or a full penetration of people's lives, but also completely changed various aspects of society as a whole: from hacker attacks, agricultural remote sensing, mapping ... and even how to find a woman friends.

    In the end can not be more accurate indoor positioning and navigation system developed  The answer is yes. In fact, the so-called indoor positioning system IPS (IndoorPositioningSystem) nearly achieved.

    Last year, Google Maps launched in the Andrews system floor plans application. Service locations including shopping malls, airports and large commercial.

    At the same time, Nokia has also developed a similar indoor positioning system. But with ordinary 2D plan, the system uses a realistic 3D model.

    Broadcom has released a support IPS chip (BCM4752), and soon smart phones equipped with this chip will be launched in the market.

    GPS and GLONASS, the IPS does not have a standard method of operation. Google's approach is via WiFi signal to track the location of equipment --- WiFi signal hotspots through recognition buildings set on the strength of the different source triangulation, roughly draw your approximate location.

    Nokia's solution is similar, but the use of the medium is a Bluetooth signal instead of the WiFi signal, and thus be able to get more accurate results. This implies the need to deploy many of the Bluetooth signal source.
