SYSTEM FOR NAVIGATION REDUNDANCY
First Claim
1. An apparatus, comprising:
- a first one or more navigation components of a plurality of navigation components;
a second one or more navigation components of the plurality of navigation components;
a navigation network component that employs one or more estimation means to develop one or more relationships for the plurality of navigation components, wherein each of the one or more relationships describes a navigation solution for a navigation component of the plurality of navigation components in terms of one or more of the plurality of navigation components; and
a health monitor component that determines one or more health indicators for the plurality of navigation components;
wherein the navigation network component determines one or more navigation solutions for the first one or more navigation components;
wherein the navigation network component determines one or more navigation solutions for the second one or more navigation components through employment of one or more of the one or more relationships and the one or more navigation solutions for the first one or more navigation components, wherein the one or more of the one or more relationships comprise one or more relationships that describe behavior of each of the second one or more navigation components in terms of one or more of the first one or more navigation components and one or more of the second navigation components.

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.
