Abstract: The system and method for position, navigation, and timing and more particularly to a system that is time and/or position independent and capable of autonomous transition from GPS to non-GPS navigation. The integrated position, navigation, and timing system uses primary and secondary navigation sensors and primary and secondary navigation measurement sources with a common time reference architecture, an integrated "dual-grid" navigation module, an integrated "dual-grid" navigation Kalman filter, and an integrated "dual-grid" navigation source selection module to provide both geodetic and relative grid timing and/or location among members of a network of platforms, particularly in GPS denied or degraded environments.

Abstract: A secure wireless transceiver, such as a link 16 transceiver, receives signals using an antenna array having an SOC associated with each antenna element in the array. The SOC's digitize and channelize received data for transmission to a message nulling system that mitigates jamming. The antenna array can be conformal, and can replace an existing Link 16 blade. The disclosed transceiver can be a modified CMN-4 transceiver with digitizing and channelizing moved to the SoC's, and replaced by the nulling system. The transceiver uses applicable TRANSEC information to assign received data to the logical Link 16 channels before nulling, and embodiments apply nulling only to channels of interest, thereby improving the nulling and reducing side lobes. Embodiments distinguish between desired and unwanted signals based on known Link 16 signal features and/or situational awareness, rather than signal amplitudes, thereby enabling nulling of even weak jamming signals.

Abstract: The present disclosure provides a spread spectrum landing system with a low probability of intercept altimeter that is in communication with a plurality of asymmetrically placed antennas or transponders near a landing area. The low probability of intercept altimeter acts as a secondary system in the event that a primary landing system for the mobile platform is denied or otherwise inoperable. The low probability of intercept altimeter cycles through unique pseudo noise (PN) codes to determine a line of sight relative to each antenna or transponder. A single algorithm or process determines and ranges the platform relative to the transponders to effectuate the landing of the platform.
