If there is only L1 signal, L1 will be sent directly when answering the call. In fact, L1 may have reflected in the atmosphere, and the refraction will cause some delays. This delay in the atmosphere will cause a lot of mistakes. Many scientists believe that atmospheric errors account for 60 % of all errors.
Signals of different frequencies pass the same medium with different refractive indexes. L5 has different L1 frequencies. The satellite transmits two signal frequencies at the same time, and the time of receiving the mobile phone is different, which gives you the opportunity to estimate the atmospheric error and then eliminate it.
The twice frequency of the GPS can only eliminate the ionization error, and the multi -diameter error cannot be eliminated (although the multi -diameter of the L5 signal is improved), and the NLOS (non -direct signal) cannot be eliminated. However, the latter two are the most important source of wrong positions in the urban environment.
