A newly installed network of sensor nodes, situated at unknown locations and orientation angles, must be located and oriented. The main issue with self-calibration is the fact that unknown signal sources are mixed into the picture. At each point in time, a calibration signal is broadcast, and a subset of sensor nodes in the network uses their local orientation coordinates to detect the time of arrival and direction of arrival of the calibration signal produced from that point. We derive the sensor node positions and orientations, as well as any unknown source locations and emission timings by processing the data from these observations. We present a solution to the self-calibration issue, along with a location inaccuracy estimate. Results are provided that use both synthetic data and field measurements.
