Satellite-Based Tolling System:
The National Highway Authority of India (NHAI) has invited expressions of interest (EoI) for the implementation of a satellite-based electronic toll collection system.
- The winning entity will have to develop a geo-referenced map and toll-charging software for the Global Navigation Satellite System (GNSS).
- A georeferenced digital map or image has been tied to a known Earth coordinate system, so users can determine where every point on the map or aerial photo is located on the Earth’s surface.
- A GNSS is the generic term for any of the satellite constellations that broadcast positioning, navigation and timing data.
- It is used in all forms of transportation like space stations, aviation, maritime, rail, road and mass transit.
- Indian Regional Navigation Satellite System (IRNSS) is an autonomous system designed to cover the Indian region and 1500 km around the Indian mainland. The system consists of 7 satellites.
- NHAI plans to implement the GNSS-based electronic toll collection system alongside RFID-based Fastags currently being used by vehicles.
- FASTag is a device that employs Radio Frequency Identification (RFID) technology for making toll payments directly while the vehicle is in motion.
