AIMED AT tracing the movement of buses introduced by Indore City Transport Services Limited (ICTSL), Global Positioning Satellite/System (GPS) will have two components - the mobile unit and the control room.
The mobile unit to be installed in every ICTSL-run bus will have a GPS antenna and a palm-sized modem. The modem with a GSM sim will be installed near the dashboard and the antennae on the bus top.
The antenna will emit continuous signals about the location of the bus through a constellation of 24 satellites launched in space by US Department of Defence in 2000.
After collecting the signals, the vehicle unit will transmit it to the control room at ICTSL head office on AB Road. “The information from vehicle unit to the control room will be sent by Global System for Mobile Communication,” informed K B Yermalkar from Arya Omnitalk Wireless Solutions Private, the Pune-based company installing GPS for the City buses.
The control room function will, however, be complex compared to the two-device mechanism of mobile unit. It will have four servers catering to different needs.
The communication server will keep tabs on every movement of each bus by collecting all their position data. Automatic Vehicle Locator System server will generate a detail map of Indore through Geographic Information System.
