Abstract: A method of calculating ionospheric scintillation includes calculating a motion-corrected perturbation of a GNSS radio signal received by a monitoring device deployed in an oceanic environment. The method includes calculating the σΦ using the high rate phase of the GNSS signal adjusted by removing the change in distance between the monitoring device and the GNSS satellite. The calculating the σΦ may further include passing the adjusted high rate phase through a high pass filter to remove a drift motion of the monitoring device. The method further includes calculating the S4 through calculating a tilt angle between the antenna of the monitoring device with the GNSS satellite and adjusting the antenna gain through known gain pattern of the antenna. The wave height of the oceanic environment may be calculated by detrending the antenna height to remove low frequency motion when a high rate position of the monitoring device is calculated.

Abstract: A sensor package and associated method provides roadside sensor-based data. The sensor package includes a controller, a network access device for remote communications, GNSS receiver, an inertial measurement unit (IMU), and environment sensors. The controller operates under software control and communicates with the other sensor package devices to: collect environment sensor data using the sensors; receive GNSS signals indicating current sensor package location; obtain IMU data; determine position/orientation data that includes position data and orientation data based on the orientation data is based on the IMU data; and send the environment sensor data and the position/orientation data of the sensor package to an external device using the network access device. The environment sensor data includes at least one sensor data frame, and the sensor data frame is matched with position/orientation data based on a time associated with collecting the sensor data frame and the position/orientation data.

Abstract: Systems and methods for deployment of a protective component, generation of a customized design for the protective component, or combinations thereof are associated with a structure comprising a portion, a neural network model, processor(s), and memory storing machine readable instructions. When executed for deployment, the neural network model predicts the likelihood of the occurrence of the natural event in the geographic area within the time frame as high as defined by when the likelihood is above a threshold, and deploys the protective component for protecting the portion of the structure when the likelihood is high. For customized design, the neural network model is used to access dimension and weather data associated with a structure and weather data to generate the customized design of the protective component for the structure.

Abstract: In some examples, interested parties would like to know the identity of various assets in a transportation environment. In some examples, the asset could be a tractor platform. In other examples, the asset could be cargo associated with a transport platform. Some of the examples described herein utilize the motion of a transport platform to power an RFID reader to read an identifier stored within an RFID tag that is coupled to an asset. In some examples, the system utilizes the identifier to identify the asset, which may be transmitted to an electronic device that is accessible to the interested parties. In further examples, a geolocation of the asset may also be transmitted to an electronic device that is accessible to the interested parties.
