About TTA AS

In 1999, John Skjelstad became involved in a unique tracking system, which unlike other tracking systems was specifically to track the movements of people.

Combining the system with extensive research into the fields of radio technology and established acoustical phenomena used to localise audio, John founded TTA in 2004 as a company dedicated to developing these technologies in the entertainment industry.

About Stagetracker II by TTA
