Operating principles
This short section gives some background information on the components in the
and how they work together to give the outputs. A short overview of the algorithm is
given and some explanation of how the software works. The section is provided as
“interesting information” and is not required for normal operation.
Internal components
Figure 40 gives a schematic view of the components in the system.
Figure 40. Schematic showing the internal components of the
The schematic shows the layout for a dual antenna system.
Strapdown navigator
The outputs of the system are derived directly from the strapdown navigator. The role of
the strapdown navigator is to convert the measurements from the accelerometers and
angular rate sensors to position. Velocity and orientation are also tracked and output by
the strapdown navigator.
Figure 41 shows a basic overview of the strapdown navigator. Much of the detail has been
left out and only the key elements are shown here.
