Tracking system

[2] The major technology “silos” in the supply chain are: Indoors assets are tracked repetitively reading e.g. a barcode,[3] any passive and active RFID, then, feeding read data into Work in Progress models (WIP) or Warehouse Management Systems (WMS) or ERP software.

Outdoors mobile assets of high value are tracked by choke point,[4] 802.11, Received Signal Strength Indication (RSSI), Time Delay on Arrival (TDOA), active RFID or GPS Yard Management; feeding into either third party yard management software from the provider or to an existing system.

Each vehicle to be tracked is equipped with a GPS receiver and relays the obtained coordinates via cellular or satellite networks to a home station.

Mobile phone servicesLocation-based services (LBS) utilise a combination of A-GPS, newer GPS and cellular locating technology that is derived from the telematics and telecom world.

As such, A-GPS enabled cell phones and PDAs can be located indoors and the handset may be tracked more precisely.

Enterprise system integrators need the skills and knowledge to correctly choose the pieces that will fit the application and geography.

GPS has global coverage but can be hindered by line-of-sight issues caused by buildings and urban canyons; Map matching techniques, which involve several algorithms, can help improve accuracy in such conditions.

This technology uses electromagnetic waves to receive the signal from the targeting object to then save the location on a reader that can be looked at through specialized software.
