The school bus GPS Tracking system enables parents and school authority to monitor school bus position in real-time. The Kerala government has declared a set of basic standard for the school bus tracking systems, by August it is mandatory that all school transport systems should be equipped with a new device, considering increased school bus accidents.

This new standard is called AIS 147 and it is the preliminary step before implementing BIS in vehicle tracking system. The AIS 147 include necessary specification maintained by GPS devices. The main functions of the device fall into two category Vehicle Location Tracking (VLT) and Emergency Button. The device shall be capable of obtaining position information using Global Navigation Satellite System (GNSS). GNSS receiver specifications are as follows:

  1. The device shall be capable for operating in L and/or S-band and include support for NAVIC/IRNSS (Indian Regional Navigation Satellite System)
  2. The Device shall support GAGAN, the Indian SBAS (Satellite Based Augmentation System)
  3. The device shall have a position accuracy of minimum 2.5 m CEP or 6 m 2DRMS
  4. The device shall have an acquisition sensitivity of minimum (-) 148 dB
  5. The device shall have a tracking sensitivity of minimum (-) 165 dB

The device shall have an internal antenna; however if in case of Integrated systems with vehicle/aftermarket OEM approved kits if the fitment location prevents the internal antenna from functioning, then external antenna shall be provided. It shall support standard minimum I/Os as mentioned: 4 Digital, 2 Analogue and 1 Serial Communication (e.g. RS232) for interfacing external systems (E.g. Digital input for Emergency request button interfacing). Should be capable of transmitting data to Backend Control Server (Government authorized server) via Wide Area (Mobile) Communications network (GSM/GPRS) as per Communication Protocol approved. The Device shall be capable of transmitting Position, Velocity and Time (PVT data) along with heading (direction of travel) to Backend Control Server (Government authorized server) at a configurable frequency as per Communication Protocol. The fixed frequency shall be user configurable, minimum frequency shall be 5 sec during vehicle operation and not less than 10 minutes in sleep/IGN OFF) as per the protocol defined in Communication Protocol and transmit data to minimum 2 different IP addresses (1 IP address for regulatory purpose (PVT data) and 1 IP address for Emergency response system other than the IP’s required for Operational purpose. On pressing of an Emergency button, the system implementing VLT function shall send emergency Alert to the configured IP address(s) as per the Communication. In the absence of GPRS network, the emergency alert shall be sent as SMS message along with vehicle location data to configured control center number(s). The Device shall have an internal backup battery to support 4 hours of normal operations (to be tested for positional record transmission at a frequency of 60 sec). Another important feature of the device is air software and configuration update. For more details please download the pdf.

    A vehicle tracking system combines the use of automatic vehicle location in individual vehicles with software that collects these fleet data for a comprehensive picture of vehicle locations. Modern vehicle tracking systems commonly.
