  • System for navigation redundancy
    Patent number: 7058505
    Abstract: An exemplary system that provides for navigation redundancy includes first and second navigation components adapted to determine first and second navigation parameters, respectively. A network component determines a relationship between the first and second navigation components, wherein the relationship describes a navigation solution for the second navigation component in terms of the first navigation component. A health monitor determines a health indicator for the second navigation component. The second navigation component determines a navigation solution for the second navigation parameters when the health indicator indicates a healthy condition. The network component determines a navigation solution for the second navigation parameters based on the relationship that describes behavior of the second navigation component in terms of the first navigation component when the health indicator indicates an unhealthy condition.
