SYSTEM AND METHOD FOR DETERMINING FLEET WIDE INTEGRITY UTILIZING BLOCKCHAIN METHODOLOGY

Abstract:

A method for determining fleet wide integrity comprises forming a user measurement block for each user in a fleet network, the user measurement block comprising: navigation measurements received by the user, relative user measurements received by the user from other users, and navigation state and integrity solutions. The user measurement block is signed and sent to all other users for validation. Each user executes a numerical process to determine a navigation state and integrity of all users. A fleet state block is formed comprising: a header including a hash of last valid fleet state block header, a nonce-proof of work, and a root hash of Merkle tree; and a data block including measurement, state, and integrity information of the fleet. The fleet state block is sent to all other users for validation. If the fleet state block passes validation, the user forms a chain of fleet state blocks.
