There is provided mechanisms for orientation determination of a wireless device with respect to a first coordinate system. A method is performed by a control unit. The method comprises obtaining first angular measurements of the wireless device at a first access node and second angular measurements of the first access node at the wireless device. The first access node is oriented in the first coordinate system. The wireless device is oriented in a second coordinate system. The method comprises determining, by aligning the second angular measurements with the first angular measurements, an amount of rotation of the second coordinate system with respect to the first coordinate system. The orientation of the wireless device with respect to the first coordinate system is defined by the amount of the rotation.

This patent concerns a compact and portable system for real-time detection and location of electromagnetic emissions in the spectrum used by mobile devices (cell phones and Wi-Fi/Bluetooth devices). The principle of detection and location is based on phased array technology, which enables the synthesis of a directional radiation beam that can be electrically controlled in terms of both its shape and direction. This technology is used primarily in military and astronomical applications. The device also includes localization and control algorithms. This device will allow for detecting and locating electromagnetic emissions by means of an antenna beam scan within a field of view of 8080 degrees. Once the detection and location have been established, the results are overlaid to a visual image captured by a video camera.
