Abstract: A device implementing a real time clock integrated module for outputting data indicating a time-of-day. The real time clock integrated module includes: a high-precision oscillator or atomic clock having an accuracy of 50 ppb (parts per billion) or better; a timing circuit for generating time-of-day data according to a clock signal outputted from the oscillator or atomic clock; a power source allowing the timing circuit to maintain time when the device is powered off. The timing circuit includes a real time clock and a logic device storing a timestamp. The timing circuit is configured when the device is powered off to update the timestamp value based on the oscillator or atomic clock and to generate a time reference signal and to provide to the device the updated timestamp value and the time reference signal that the device can use as a time reference once the device is powered up again.

Abstract: A method, non-transitory computer readable medium, and device that transmits a cryptographic variable input to a detachably coupled smart card. Execution of at least one of protected cryptographic algorithm operation by the smart card which requires the cryptographic variable input and a cryptographic constant input stored on the smart card to generate one or more cryptographic products is requested. The one or more generated cryptographic products from the smart card are received. An encrypted signal simulation based on execution of a simulator using the received one or more generated cryptographic products is generated and is output.

Abstract: An anechoic chamber and test system that is adapted for installation in or to a vehicle. The chamber includes an outer structure that is durable enough to withstand the effects of transportation. The anechoic chamber and test system may also include an inner faraday shield, a transmission antenna, and a controller that can introduce GNSS, alternative navigation signals, jamming, or spoofing signals into the anechoic chamber along with vehicle sensor signals. The controller is adapted to monitor a GNSS system's ability to resist the jamming or spoofing signals using, at least in part, the vehicle sensor signals.

Abstract: This technology includes methods, non-transitory computer readable media, and pattern navigation aiding devices that obtain one or more images of a section of sky. Stars comprising at least one or more artificial stars in the one or more obtained images of the section of the sky that are in an image pattern that match above a set threshold at least one previously shared beacon pattern are identified. Navigational information from the identified image pattern with the at least one or more artificial stars that matches above the set threshold the at least one previously shared beacon pattern is determined and output to provide navigational assistance.
