    Abstract: One or more computing devices, systems, and/or methods for detecting spoofing attacks are provided. Location information of a base station may be evaluated to determine a true position of the base station. Satellite signals received by the base station may be processed and evaluated to calculate a real time position of the base station. A distance between the real time position and the true position may be calculated. In response to the distance exceeding a threshold distance, an alert is generated to indicate that the base station is experiencing a spoofing attack.

    Abstract: One or more computing devices, systems, and/or methods for calibrating barometric sensors and/or determining altitudes of devices are provided. In an example, a device is determined to be outdoors. In response to determining that the device is outdoors, a calibration process associated with a barometric sensor of the device is performed. The calibration process includes performing one or more barometric measurements using the barometric sensor to determine one or more barometric pressure measures, determining one or more locations of the device, wherein the one or more locations are associated with the one or more barometric measurements, and determining a barometric offset based upon the one or more barometric pressure measures and one or more reference values. An adjusted barometric pressure and/or an altitude of the device is determined based upon a first barometric pressure measure and the barometric offset.

    Abstract: One or more computing devices, systems, and/or methods for generating profiles, such as weather profiles, based upon signals from vehicle devices are provided. In an example, a plurality of vehicle measure signals is received from a plurality of vehicle devices. A first vehicle measure signal of the plurality of vehicle measure signals is received from a first vehicle device, of the plurality of vehicle devices, connected to a first vehicle. The first vehicle measure signal is indicative of a first location of the first vehicle and one or more first vehicle measures determined using one or more first sensors of the first vehicle. A vehicle measure profile associated with a region is generated based upon the plurality of vehicle measure signals. The vehicle measure profile is indicative of one or more second vehicle measures at one or more locations within the region.

    Abstract: One or more computing devices, systems, and/or methods for calibrating barometric sensors and/or determining altitudes of devices are provided. In an example, one or more barometric pressure measures are determined using a barometric sensor of a device. One or more locations of the device are determined based upon one or more global navigation satellite system (GNSS) signals and one or more corrective signals associated with the one or more GNSS signals. One or more reference values are determined based upon the one or more locations. A barometric offset is determined based upon the one or more barometric pressure measures and the one or more reference values. A first barometric measurement is performed using the barometric sensor to determine a first barometric pressure measure. An adjusted barometric pressure measure and/or an altitude of the device are determined based upon the first barometric pressure measure and the barometric offset.
