scalability is one of the most investigated technology on the
market. The accuracy provided by satellites-based positioning
systems (i.e., GLONASS or Galileo) is not always sufficient when
a decimeter-level accuracy is required or when there is the need
of localising entities that operate inside indoor environments.
Scalability is also a recurrent problem when dealing with indoor
positioning systems. This paper presents an innovative UWB
Indoor GPS-Like local positioning system able to tracks any
number of assets without decreasing measurements update rate.
To increase the system’s accuracy the mathematical model and the
sources of uncertainties are investigated. Results highlight how
the proposed implementation provides positioning information
with an absolute maximum error below 20 cm. Scalability is
also resolved thanks to DTDoA transmission mechanisms not
requiring an active role from the asset to be tracked.
