Frederick Raab

Frederick Raab is an engineer who has played a part in creating electromagnetic 3D tracking systems.^[1]

He specializes in radio-frequency (RF) power amplifiers.

He runs a company named Green Mountain Radio Research (GMRR).

He was an employee of Polhemus starting in 1975 and ending in 1980.^[2]

Magnetic tracking studyEdit

The fields scattered by helmet-mounted CRTs can significantly degrade the performance of a magnetic-field helmet-mounted sight. Under contract to U.S. Air Force Aerospace Medical Research Laboratory, GMRR developed a multipole model of this phenomenon and software for extraction of its parameters. Laboratory measurements showed that the dipole terms of the model predict the scattered fields with no more than a 16-percent error. The residual field-prediction error was shown to be due to noise and multipole components.^[2]
