Multi-axis single-anchor vs. single-axis multi-anchors in long-range 2D MQS positioning

Recent developments have enabled single-anchor long-range two-dimensional (2D) positioning using low-frequency magnetoquasistatic fields. The approach of using a single-anchor for 2D position and orientation sensing results in significantly simplified systems and setup when compared to previous multi-anchor systems. The various advantages of single-anchor systems over multi-anchor systems include accurate closed-form inverted solutions, substantially simplified system setup and calibration, no relative ground truth needs, and ability to easily perform low-latency or real-time sensing with simple systems.
