On-board backup and anti-spoofing GPS system

摘要

Disclosed is an on-board backup and anti-spoofing GPS (“OBASG”) system for navigating a vehicle through an environment with a GPS receiver. The GPS receiver is configured to receive GPS signals within the environment where the GPS signals may suffer a GPS outage or are unreliable within the environment. In general, the OBASG includes a GPS block-chain recorder, a block-chain storage module, an anti-spoofing module, and a backup navigation module.
