????The GPS module has a parameter for the number of channels, such as 20 channels, which indicates that the module can establish communication with up to 20 satellites simultaneously. The three satellites are 2D positioning, and the data is unstable. The module can only obtain accurate positioning data after complex calculations after receiving signals from more than three satellites at the same time. If the number of satellites communicating at the same time is more, the module can obtain positioning data faster and more accurately, In a typical urban environment on the Earth's surface, it is usually possible to communicate with 4-11 satellites simultaneously.
