As mentioned earlier, the working frequency of the GPS signal is divided into several frequency bands, such as L1, L2, and L5:
Frequency band L1: 1575.42MHz ± 1.023MHz
L2 frequency band: 1227.60MHz ± 1.023MHz
L5 frequency band: 1176.45MHz ± 1.023MHz
In the past, GPS positioning was performed using the L1 frequency band, which is a unique frequency positioning method. At present, the GPS chip uses the L1 + L5 frequency band for positioning, which is called multi -frequency positioning technology. For example, the Broadcom BCM47755 chip declares that it supports multiple frequencies L1 and L5. Positioning: Remember, there is a concept of a double star positioning (GNSS), and the GPS dual -frequency positioning is not a complete event. We have discussed in the past.
The GPS dual -frequency positioning can only eliminate the ionizing layer error, and the multi -diameter error cannot be eliminated. Therefore, it is not obvious to improve positioning accuracy in an open environment and expecting to improve positioning accuracy in the urban area of dense buildings. Dual-frequency GPS is expected to become a future development trend that can effectively improve positioning accuracy (estimated to be 3-5 meters), but this is not a revolutionary change.
