Navigation architecture for contested environments

A system for navigation path planning in a contested environment, the system comprising:

• one or more processors;
• and
• a storage operatively coupled to the one or more processors and configured to store instructions that when executed by the one or more processors cause a process to be carried out, the process including:
• receiving an initial position of a navigation path and a terminal position of the navigation path;
• calculating the navigation path from the initial position to the terminal position as an objective function of a navigation reliability term and a navigation accuracy term, the navigation reliability term representing a probability of successfully reaching the terminal position along the navigation path, the navigation accuracy term representing a distance between the terminal position and the navigation path;
• and
• providing the calculated navigation path to a navigation system to cause a platform to navigate along the calculated navigation path.

A computer program product including one or more non-transitory machine-readable mediums encoded with instructions that when executed cause a process to be carried out for navigation path planning, the process comprising:

• receiving an initial position of a navigation path and a terminal position of the navigation path;
• calculating the navigation path from the initial position to the terminal position as an objective function of a navigation reliability term and a navigation accuracy term, the navigation reliability term representing a probability of successfully reaching the terminal position via one or more navigational fixes to be obtained from a platform while navigating along the navigation path, wherein the probability of successfully reaching the terminal position is based at least in part on a probability that each of the navigational fixes can be successfully obtained while navigating along the navigation path, and the navigation accuracy term representing a distance between the terminal position and the navigation path;
• receiving an image of at least one of the one or more navigational fixes;
• comparing one or more features of the image to one or more corresponding features of a reference image associated with a known geolocation;
• registering the at least one navigational fix based on the comparison;
• and
• providing the at least one navigation fix to the navigation system.
