System and method for dismounted assured position, navigation and timing (DAPNT)

Abstract:

A process described herein may be used to determine a first asset's position in a GNSS-limited environment. The process includes transmitting a current position for each of at least three additional assets in wireless messages by wireless transmitters. The current position for each of the at least three additional assets is determined using previously received position data and one more additional measurement generated by instruments on board the additional assets. The transmitted messages are received at a device of the first asset and a processor on the device implements pre-programmed instructions to access the current position for each of the three additional assets and determine the first asset's position using the current position for each of the three additional assets.
