Three modes switch
What is GPS and LBS positioning 1. GPS (Global Positioning System, global satellite positioning system), GPS positioning is performed by receiving longitude and latitude coordinate signals provided by GPS satellites. 2. LBS (LBS-Location Based Service, mobile location base station system), and LBS calculates the location of the mobile phone through the difference of the base station signal of mobile communication.
LBS, base station location service, is to locate the location information (longitude and latitude coordinates) of terminal equipment through the mobile network base station of the operator, and provide location services for enterprise users. Its working principle is also very simple: the base station is uniquely determined in the mobile network, and its geographic location is also unique, and the distance between the three base stations (three points) and the hardware device can be obtained. According to the three-point positioning principle, it is only necessary to draw a circle multiple times with the base station as the center and the distance as the radius. The intersection of these circles is the location of the hardware device. Both positioning have their own advantages, but they also have shortcomings 1. GPS positioning: The advantage of GPS positioning is accuracy. As long as it can receive positioning signals from four satellites, it can be positioned within 5-10 meters. In GPS positioning, because the receiver is covered by at least 4 satellites at any time, the signal is well guaranteed, and because the satellites are condescending, and the satellite clock and atmospheric interference are excluded, the accuracy can also be guaranteed within a few meters to tens of meters. The disadvantage is that GPS is greatly affected by weather and location. When the weather is bad, or under a viaduct/shade, or in the corner of a tall building, an underground garage or an open-air lower garage (or simply when the sky is not visible), GPS positioning is Will be greatly affected, and even unable to perform location services. 2. LBS positioning: The advantage of LBS positioning is that it is convenient because it is positioned through a mobile phone, which is of great significance to the energy consumption of the device and extending the standby time. Theoretically, as long as the signal difference of the three base stations is calculated, the location of the mobile phone can be judged. Therefore, as long as the user's mobile phone is within the effective range of the mobile communication network, location positioning can be performed at any time without being affected by weather, tall buildings, location, etc. LBS positioning is subject to two restrictions. (1) The position coordinate value obtained by calculating the signal difference of the base station is obviously inferior to the positioning accuracy of GPS (the accuracy of LBS base station positioning ranges from 500-5000 meters); (2) The use range is narrow. Although LBS will not be affected by weather, viaducts or tall buildings, if it exceeds the service range of the mobile phone, or the number of base stations where the mobile phone is located is insufficient, LBS positioning cannot be performed. (3) The influence of the repeater on the base station data; (4) If the database is not updated in time, mobile communication operators may change, add, or delete base station numbers at any time. From this point of view, it is not suitable for field use. Mobile phone positioning is based on the existing mobile phone communication base stations, which is greatly affected by the environment. Due to the scarcity of base stations, mobile stations are located within the range of 1000-2000 meters in the suburbs and rural areas; the positioning range is 100-200 meters in the urban area, and it cannot be received The location of the mobile phone signal cannot be discussed.
