  As mentioned in the advertisement promoted by Xiaomi a while ago, GPS dual band positioning, ultra precision, we all know that GPS=Global Positioning System is a global positioning system developed in the United States. At present, it is very mature and widely used, not only in airplanes, cars, mobile phones, but even in children's watches, it can provide positioning. But what are the working rules of GPS? Below, the editor will briefly introduce the relevant concepts.

  GPS is classified into single frequency receivers and dual frequency receivers based on the carrier frequency of the receiver. A dual frequency receiver can simultaneously receive carrier signals such as L1 and L2. Everyone knows that network speed does not have a major impact on the retrieval of positioning data. Positioning satellites are subject to varying degrees of interference from electrical, electromagnetic, radio, strong magnetic fields, and other factors when retrieving data from each other; However, the use of dual frequency for ionospheric delay can eliminate the impact of ionospheric delay on electromagnetic wave signals. Therefore, Xiaomi boldly attempts to apply GPS dual frequency positioning to mobile phones. Dual frequency data can be combined without ionosphere, improving positioning accuracy. After countless tests, Xiaomi 8 finally enabled the L1 and L5 dual frequency carrier signals of GPS, as shown in the following figure:

  Next, let me talk about our BeiDou satellite positioning system. In this era of accurate positioning, users need to pursue more precision and accuracy in positioning. The existence of three frequencies can form an ultra wide lane combination, which improves the speed of ambiguity resolution. BeiDou adopts three navigation frequency bands: B1, B2, and B3. Corresponding to the following:

  B1 frequency point: 1559.052MHz -1591.788 MHz

  B2 frequency point: 1166.22MHz -1217.37 MHz

  B3 frequency point: 1250.618MHz -1286.432 MHz
