What Role Does GPS Play?What Role Does GPS Play?
GPS’ role in automated cars is rather limited. GPS must be integrated with GPS’ role in automated cars is rather limited. GPS must be integrated with sensor and laser technology in order to account for obstacles in the road sensor and laser technology in order to account for obstacles in the road and heavy traffic.and heavy traffic.
GPS already plays a role in terms of navigation and personal convenience GPS already plays a role in terms of navigation and personal convenience (e.g. ONSTAR), but is unlikely to facilitate safe, fully automatic (e.g. ONSTAR), but is unlikely to facilitate safe, fully automatic performance in the near future in urban areas.performance in the near future in urban areas.

Whatever forms these automated inventions Whatever forms these automated inventions take, they will almost certainly require GPS to take, they will almost certainly require GPS to make them work. Moreover, falling price and make them work. Moreover, falling price and mainstreaming of GPS technologies will make mainstreaming of GPS technologies will make these technologies even more cost-efficient. these technologies even more cost-efficient.
