Effect of Space Weather on Autonomous Vehicle Navigation 2019-01-0694
Autonomous vehicle systems integrate multiple information systems. Navigation is reliant on global positioning systems (GPS) which are supported by a satellite network. However, satellites and radio signals are subject to interference from sunspots. Sunspots happen on regular cycles at varying strengths but their occurrence can’t be exactly predicted. The likelihood of a severe solar event is roughly twelve percent per decade. Moderate solar events could impair navigation. Results will show the likelihood of each event and its consequence on autonomous vehicle navigation. In the worst case scenario, satellites could even be permanently damaged by severe sunspots. As autonomous vehicles become a more significant portion of the economy, it is necessary that they have resilience operate in extreme conditions. Alternative navigation procedures are proposed to enhance the resiliency of autonomous vehicles. Artificial intelligence related to place identification, inertial position tracking, relative geographic navigation, and storage of most common routes are some of the options.
