    摘要: A system and method for providing time stamps protected from GPS timing signal attacks. A GPS receiver receives a GPS time data, and a local clock provides local time data. A controller initiates the local clock with the GPS time data. It continuously monitors the GPS time data by calculating any difference error between current GPS time data and local time data, and determining whether the error exceeds a threshold value. If the error does not exceed the threshold value, the GPS time data is used to discipline the local clock data and the disciplined output is used for the time stamp. If the error exceeds the threshold value, the local time data is used for the time stamp.

    摘要: The present disclosure relates to a network routing overlay (NRO) system. The NRO system includes an NRO master that includes an NRO master module and a master network interface. The NRO system further includes a first plurality of NRO remote systems (RSs). Each NRO RS includes an NRO RS module, an internal network interface and an external network interface. The external network interface is related to an NRO interface. Each NRO RS is coupled to the NRO master by a respective data channel and a respective control channel. A first NRO RS is configured to receive a network frame from an end system coupled to the first NRO RS via a first NRO interface. A first NRO RS module is configured to generate an NRO message and to write the NRO message to a first data channel. The NRO message includes an NRO prefix and the received network frame. The NRO prefix includes a length and a frame identifier (ID). The first data channel is configured to carry an NRO frame that includes one or more NRO message(s). The NRO master module is configured to extract the network frame based, at least in part, on the length and frame ID.

    摘要: A system and method for measuring length of an electrical power transmission line, and for estimating the average temperature of the line over the measured length. A signal is applied to the line and reflected from a reflection point to obtain a present measure of the line's length. A modified catenary equation uses the length measurement and other variables to estimate average temperature. This temperature measurement can then be used to determine how much power the line is presently capable of safely carrying.
