That’s better, thank you

As a holder of a spatial degree I found it difficult to directly compare it favourably to GNSS. Even a simple binary code calculating a position with GNSS gives sub 10-20 metre accuracy, generally closer to 2 or 3.

    I don't think it's meant to be better than GNSS in terms of accuracy, just better in terms of reliability because it works entirely standalone without a need for satellite
