摘要： The present disclosure generally relates to a method for testing a telecommunication standard-based positioning, navigation, and timing system and a test device. The system includes the test device. Radio signals from at least three different transmitters are received by the test device. Each transmitter transmits a radio signal according to the telecommunication standard. An assessed position of the test device is determined based on the radio signals received by the test device. The position of the mobile device is determined by the test device additionally to the assessed position. The assessed position is compared with the determined position.

摘要： A method of training an artificial intelligence circuit is provided. The method includes the steps of providing a training data set, the training data set encompassing training data of a frequency spectrum including a guard band and/or training data concerning a radio frequency power in the guard band, and feeding the training data set into the artificial intelligence circuit to be trained, which processes the training data set in order to learn a standard frequency spectrum and/or a standard radio frequency power in the guard band, thereby enabling the artificial intelligence circuit, when trained, to determine a deviation from the standard frequency spectrum and/or to determine a deviation from the standard radio frequency power in the guard band. In addition, a monitoring method for identifying an anomaly in a radio frequency spectrum as well as a system for monitoring a radio frequency environment are described.

摘要： A vehicle black box includes a sensor interface for receiving sensor data of a sensor module sensing at least one physical vehicle parameter. Further, the vehicle black box includes a wireless module for receiving a radio frequency signal, wherein the wireless module generates IQ data based on the radio frequency signal received. The vehicle black box also includes a recording module with a first memory for temporarily storing the IQ data generated and a second memory for permanently storing the IQ data generated. Moreover, the vehicle black box has a processing unit configured to receive and evaluate the sensor data. The processing unit is further configured to control a transfer of the IQ data from the first memory to the second memory based upon the evaluation result.

摘要： A terrestrial positioning system includes a mobile terrestrial transmitter including a local clock source and an inertial measurement unit, and a synchronization master including a memory configured to store initially known positioning information of the terrestrial transmitter. The terrestrial transmitter determines altered positioning information of the terrestrial transmitter using the first IMU and broadcasting a positioning signal including a timestamp. The synchronization master calculates an expected time of flight of the received positioning signal based on the determined altered positioning information and the stored initially known positioning information of the terrestrial transmitter, to determine a first deviation of the actual time of flight determined from the timestamp and the actual reception time of the received positioning signal with respect to the calculated expected time of flight and to instruct the terrestrial transmitter to delay or prepone the broadcast of the positioning signal.
