Probabilistic Framework for the Positioning Of a Vehicle in a Combined Indoor-Outdoor Scenario

The development in technology has given
us all sophistications but equal amounts of
threats too. This has brought us an urge to
bring a complete security system that
monitors an object continuously. Consider
a situation where a cargo vehicle carrying
valuable material is moving in an area
using GPS (an outdoor sensor) we can
monitor it but the actual problem arises
when its movement involves both indoor
(with in the industry) and outdoor because
GPS has its limitations in indoor
environment. Hence it is essential to have
an additional sensor that would enable us a
continuous monitoring /tracking with out
cutoff of the signal. In this paper we bring
out a solution by combining Ultra wide
band (UWB) with GPS sensory information
which eliminates the limitations of
conventional tracking methods in mixed
scenario(indoor and outdoor) The same
method finds application in mobile robots,
monitoring a person on grounds of
security, etc.
