Our latest L1/L5 dual-band GNSS platform provides meter-level accuracy in urban environments.

Dense urban areas pose challenges for GNSS receivers in acquiring satellite signals. The foliage of trees and buildings can interfere with the path of these signals by diffracting or reflecting them, creating what is known as multipath effects.

These multipath effects introduce errors that ultimately affect the accuracy of GNSS receivers, which can be significant. Comparing the receiver's position accuracy in a rural environment to an urban area can vary considerably, for example, from 2 m to 30 m.     

Multipath does not affect all signals equally. L5 signals are much more resilient to these effects. So when a receiver combines L1 and L5 bands and a multipath environment is detected, the GNSS firmware algorithm can use more L5 signals for navigation than L1.

The F10 is u-blox’s meter-level dual-band GNSS platform, combining the L1 and L5 bands. This combination improves multipath resistance and accuracy of meter-level positioning.

In addition, the F10 platform incorporates sophisticated algorithms to detect jamming and spoofing attacks, provides high robustness against RF interference from co-located cellular modems, and is pin-to-pin compatible with the previous generation.
