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.

Abstract: A system and method are provided for detecting local interference in GPS signals. A plurality of remotely located GPS receivers are capable of receiving GPS signals and producing GPS related data. A monitoring station is capable of storing at least one expected GPS parameter for each of the plurality of GPS receivers. A first processor at the monitoring station is programmed to determine, for each of the GPS receivers, whether said GPS related data deviates from any of the at least one GPS parameter by more than a predetermined range of error, and for issuing a warning in response thereto.
