When one of the GPS antennas fails is there another way to get a GPS signal? What are the alternatives?

When the GPS antenna fails, it can't receive the satellite signal and can't locate, so for fully autonomous driving or fully autonomous vehicle, multi-redundancy design is very necessary, which can greatly improve the reliability of our equipment.

As for the backup devices, we usually choose some common antennas and modules to do dual-algorithm and dual-fusion design. So that even if one set of system fails, another set of system can be stably intervened to do auxiliary work, which can achieve better stability. In addition, for dual redundancy design, we also have some products for fully autonomous UAVs.
