Magneto-electro-quasi-static (M/EQS) Field

---

Basic Concept

• 3-axis emitter and 3-axis sensor – sensor detects fields and solves for positions & orientation Sensors are simple and small (palm sized and lightweight) 
• No requirement for triangulation to determine position
• Operational ranges approximately measured up to 200m with a single transmitter node and may be extendable to kilometers with an array network

M/EQS fields

• Not significantly perturbed when line-of-sight is blocked or near lossy objects 
• Require coils to emit and detect fields - Sensed magnetic fields are immune to multi-path 
• M/EQS algorithms can correct the errors due to challenging ferromagnetic environments Demonstrated within centimeter level (~10cm) resolution for PNT (optimized system)
