The RT3000 family products are advanced, precision Inertial and GPS Navigation systems for measuring motion, position and orientation.
They use Inertial Navigation System (INS) technology and combine this with the highest quality Survey Grade GPS receivers. The best attributes of Inertial Navigation Systems and GPS are blended together to give an optimum solution.
The systems improve the performance over GPS-only ones by providing accurate velocity in urban or tree-covered environments. The drift common to conventional Vertical Reference Units (VRU) or Stabilized Platforms is corrected automatically so that the RT3000 family products can be used indefinitely without drifting or needing to be reset.
