Abstract
In a tactical missile with mid-course guidance, an
Inertial Navigation System (INS) is required. Strapdown INS
using Steady-State Kalman Filters (SKF) as estimators has
been suggested and this kind of INS is considered to be
easier and cheaper to implement than the gimbaled INS.
This thesis investigates one aspect of the INS problem:
The sensitivity of the SKF to inaccuracies in the filter
parameters such as the stability derivatives. The analysis
has been performed by varying each of the flight parameters
over a given range and noting the effect on the accuracy of
the filter. The great advantage of the analysis in the
sensitivity of rms estimate errors to inaccuracies in the
stability derivatives is that it points out clearly which
derivatives are worthy of detailed accurate determination and
which are not.
