INTRODUCTION

According to the dictionary guidance is the ‘process of guiding the
path of an object towards a given point, which in general may be moving’. The
process of guidance is based on the position and velocity if the target relative to
the guided object. The present day ballistic missiles are all guided using the
global positioning system or GPS.GPS uses satellites as instruments for sending
signals to the missile during flight and to guide it to the target. SATRACK is a
system that was developed to provide an evaluation methodology for the
guidance system of the ballistic missiles. This was developed as a comprehensive
test and evaluation program to validate the integrated weapons system design for
nuclear powered submarines launched ballistic missiles.this is based on the
tracking signals received at the missile from the GPS satellites. SATRACK has
the ability to receive record, rebroadcast and track the satellite signals.
SATRACK facility also has the great advantage that the whole data obtained
from the test flights can be used to obtain a guidance error model. The recorded
data along with the simulation data from the models can produce a
comprehensive guidance error model. This will result in the solution that is the
best flight path for the missile
