Compassing in Harsh Environments: Correcting for Magnetic Field Distortion

 

Compassing in Harsh Environments: Correcting for Magnetic Field Distortion; by Andrew Leuzinger, October 2010

Today's electronic compasses are built to withstand harsh environments - mechanical shock, extreme temperature and battlefield conditions. Yet the most challenging environment for compassing are the permanent and transitory magnetic field distortions encountered in everyday situations. This article discusses the recent developments in software to overcome transitory magnetic field distortions.
