With the advances in electronics and the broad usage in wireless
communication,an accompanied promising technology is revealing
its importance. That is position location. The
applications with position location are various,
including personal safety, fleet management, accident reporting,
navigational services, roadside assistance, cargo tracking,
automated billing, fraud detection, and etc.
In this thesis, we make a survey of existing position location
algorithms at first. After making a comparison among these
methods, a suitable one is chosen to apply in our system. Then
we design each component of the system by describing its
functions, designing related protocol features and message
formats. At last, a simulated test is given to prove the
correctness and practicability of the proposed system --
NGPLS.
