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: A system and process for determining a communication status of an environment is disclosed. Sensors in the environment acquire data about the environment, and a first subset of the data is used to compute a first penalty about the environment, which is computed using a first algorithm that includes a maximum penalty and a decay rate at which the penalty decays over time. Further, a second subset of the data is used to compute a second penalty about the environment. The second penalty is computed using a second algorithm that also includes a maximum penalty and a decay rate at which the penalty decays over time. The first and second penalties are compiled to create an overall environmental penalty that represents a current status of the environment, which is compared to a threshold. If the overall environmental penalty exceeds the threshold, then an action, including issuing an alarm, is performed.
