Introduction

Spatial FOG is a ruggedised GPS aided inertial navigation system and AHRS that
provides accurate position, velocity, acceleration and orientation under the most
demanding conditions. It combines ultra high accuracy fibre optic gyroscopes,
accelerometers, magnetometers and a pressure sensor with an RTK GNSS receiver.
These are coupled in a sophisticated fusion algorithm to deliver accurate and reliable
navigation and orientation.
Spatial FOG can provide amazing results but it does need to be set up properly and
operated with an awareness of its limitations. Please read through this manual
carefully to ensure success within your application.
The Spatial FOG Manager software is downloadable from the software section. It allows
Spatial FOG to be easily configured and tested. It is referenced throughout this
manual.
