1. A method, comprising:
receiving sensor data from a sensor carried by a platform, wherein the sensor is part of a non-navigation system on the platform;
transforming the sensor data into a format to be used by a routing system on the platform;
generating a route by the routing system based, at least in part, on the sensor data that has been transformed into the format for use by the routing system;
moving the platform along the route, wherein the route is based, at least in part, on the sensor data from the sensor that is part of the non-navigation system on the platform;
receiving navigation data from a navigation system on the platform, wherein the navigation system includes at least one of a global positioning system (GPS) and an inertial navigation system (INS);
generating the route by the routing system based, at least partially, on the navigation data for use by the routing system;
moving the platform along the route, wherein the route is based on the sensor data and the navigation data;
determining that the navigation system is not operable;
continuing to move the platform along the route while relying on the sensor data and not relying on the navigation data while the navigation system is inoperable; and
reducing inertial drift calculations in response to integrating angular rates of platform attitude while the platform is moving and after it has been determined that the navigation system is inoperable.
