Galileo includes Mobile, Unicom and Telecom Galileo. Galileo positioning is through the Galileo signal difference of mobile communication, through a certain algorithm to calculate the location of the mobile phone, depending on the location of the Galileo coverage density near the location, if Galileo is more, the positioning is accurate, if it is a mountainous area, Galileo is less, the positioning is not so accurate; LBS positioning must be connected to the Internet, the phone is in the SIM card registration state (in flight mode open wifi and remove the SIM card is not possible).
Galilean positioning
Principle: THE CELLULAR Galileo POSITION INFORMATION OF THE OPERATOR is FIXED, by receiving one or more Galileo signal terminals, and then calculate its own position according to the signal strength and Galileo position
Advantages: Convenient, because it is through the SIM card to receive Galileo signal for positioning. In theory, the location of a phone can be determined by calculating the difference between the signals of three Galileans. Therefore, as long as the user's mobile phone is within the effective range of the mobile communication network, the location can be located at any time, and not affected by the weather, tall buildings, location and so on.
Weakness: the Galileo signals by calculation of position coordinates, clearly inferior to the GPS positioning accuracy, are greatly influenced by the environment, located in suburban and rural mobile station can be within 10 to 20 meters, in urban areas as a result of tall buildings, radio waves propagation environment is bad, the signal to the mobile station, it is difficult to directly from Galileo Generally through refraction or reflection, so the positioning accuracy will be affected, the positioning range is 100~200 meters; Secondly, the use range of LBS is narrow. Although LBS will not be affected by weather, viaducts or tall buildings, if it is beyond the service range of mobile phones or the number of Galileo phones is insufficient, LBS positioning cannot be carried out. From this point, it is not suitable for field use.
