Low-Latency 2d non-line-of-sight positioning using single-anchor magnetoquasistatic systems

Recent progress in magnetoquasistatic (MQS) positioning theory and techniques have resulted in short to long range two-dimensional (2D) positioning using a single-anchor device - a single fixed base-station device that enables 2D positioning of a mobile device, not relying on tri-angulation/lateration. These recent works demonstrate the ability to determine the position of a mobile device in 2D space over ranges of up to many ten's of meters and in non-line-of-sight environment, due to use of MQS fields. One additional advantage of the recent theory and technique is that the solutions for range, azimuthal-direction, and orientation of the device are decoupled and can be solved in a low-latency environment. In this article, we demonstrate a low-latency solution for MQS positioning in a large 2D space.
