G4 ™

The 6DOF Wireless, Precision Motion Tracker That Fits in Your Pocket!
Polhemus G4

G4 is a compact, highly accurate wireless electromagnetic 6DOF motion tracker. The system provides real-time motion measurement, delivering the precision motion tracking that Polhemus’ proprietary electromagnetic technology is known for, yet the G4 hub fits in the palm of your hand.

Precision. Performance. Portable.

The size of most mobile phones, G4 has a sleek design, and can be belt-worn. G4  provides tetherless motion tracking, and allows for complete freedom of movement. G4 provides drift-free, highly accurate data results producing repeatable tracking performance. It’s ideal for applications that require precision motion tracking, as it satisfies the standards of top researchers and meets the mark for the military.  

Among motion tracking technologies, there are products that capture motion—and there are those that measure motion. G4 sets the standard for motion measurement, taking it to the next level. It boasts a resolution fine enough to measure even the slightest change in movement--without line of site occlusions. Data results provide both position and orientation calculations, without the complications of hybrid technologies.

10+ Hours of Battery Life
