u-blox F9 technology

• There is no single technology capable of providing the required position accuracy in all environments

• u-blox F9 uses a tight combination of core GNSS technologies:

• to smooth multipath effects, bridge obstructions

• maintain positioning in tunnels & parking garages in automotive navigation

• delivering down to centimeter-level accuracies

• for a large number of direct line-of-sight measurements

• for fast convergence & re-convergence of high precision positions
