Mobile Positioning

Mobile phone positioning refers to through wireless terminals (mobile) and wireless networks to cooperate, to determine the actual location of the mobile user information (geodetic coordinates system data, including 3d data), through SMS, MMS, speech to a user or basis to provide a certain value-added services.

Mobile phone positioning definition

Mobile phone positioning refers to through certain positioning technologies to obtain mobile phone or end-user position information (geodetic coordinates system), in the electronic map is positioned object position technology or services. Positioning technologies have two kinds, one kind is based on GPS positioning, one kind is based on mobile operation network of the base positioning. Based on GPS positioning method utilizes, the GPS phone module will own position signal sent to positioning backend realize mobile phone positioning. Base station location is to use mobile phone base stations to measure the distance from the distance to determine the position of the mobile phone. The latter does not need handset with GPS positioning ability, but precision depends largely on base of the distribution and the covering of size, sometimes error will be more than a kilometer. The former positioning accuracy.

The latest mobile positioning technology USES positioning on cell phones communication module to assist GPS phone positioning, main modules improvement lies in

1. Indoors where no GPS signals using base station location to provide location information, narrow orientation blind spots

2. In GPS module start searching star stage, through the base station location to determine the location of the general location, through the mobile phone gets the GPS satellite cellphones star calendar diagram, can quickly search star, the display stage time by star for 2-3 minutes, reduced to 10 seconds

Typical application

Parents positioning old person, children; Mainly for safety and care needs,

Enterprise of vehicle management; Out of GPS high cost and basement, etc have no signal of reasons, some logistics enterprises to adopt the mobile GSM positioning technology solutions. This scheme is the cost of GPS 1/3. But by mobile base station network resource constraints, in continuous localization of the high cost.

Enterprise employees on management, Can provide to have multiple division sales company, the sales team work time work management;

Remotely, the other party number in decoding cell phones or fixed-line internal procedures, and bind his number, and bind after can undertake no restrictions distance monitoring, interception, positioning function.
