Differences and application selection between dual-band and single-band GNSS signals

Compared with single-band, dual-band GNSS signals have higher positioning accuracy and anti-interference ability, and are suitable for industries such as automobiles, agriculture, construction and mining. Dual-band signals mainly include L1, L2 and L5 bands, of which L1 band is widely used in the mass market, L2 band can penetrate obstacles such as clouds, trees or buildings, and L5 band has stronger anti-multipath effect and anti-interference ability. When choosing dual-band or single-band, it is necessary to consider the specific needs of the application scenario, such as asset trackers, wearable devices, vehicle trackers, commercial UAVs, ground robots and self-driving cars.
