How to make the data of the GPS positioner more effective

????

????Positioning data is effective or invalid, and other important information. Software reads latitude and longitude data to obtain the user position to stop the analysis, and it is affirmed that the detailed location of the user establishes war in the region. The method is based on the setting of the latitude, longitude and latitude and longitude of the user's setting affirmation center, to calculate that the event to maintain the current object can surpass the radius of the predetermined by war activities. The discrimination on the bottom of the result sets the corresponding logo.

????The slot machine itself is equipped with remote coding and remote adjustment. This is exactly the acceptance and launch installation of the machine. There are two types of frequency codes for the transmission of the acceptor, that is, the fixed code and the rolling code. In the promotion of replacement products, all places where confidentiality requests are losing secret uses rolling coding methods. The current field use is full of rolling codes. The processing of scrolling code is "scout" to obtain. When the frequency code positioning effect is very complete, the field is used in general use. Positioner, I hope everyone is clear.

????There are two types of mobile phone positioning technology, one is the positioning of GPS, and the other is the positioning of the base station based on the mobile operation network. The GPS -based positioning method is to use the GPS positioning module on the mobile phone to accept the signal issued by the GPS satellite, and apply these signals to stop the navigation positioning.

????The base station positioning is to affirm the location of the mobile phone by the calculation interval of the base station's interval between the mobile phone. The latter does not require the mobile phone to have GPS positioning, but the accuracy is large and the level depends on the distribution and cover range of the base station, and sometimes the error will exceed one kilometer. The former has a higher positioning accuracy. In addition, WiFi is used in a small way.
