Indian Railways ties up with ISRO for real-time train tracking

Published: 9th Mar, 2023

Context

The Indian Railways is utilising data analytics for seamless transit. Under the Real Time Train Information System (RTIS) project, it has started a project that will now allow real-time tracking of train movements with the help of satellite photography.

About:

Railways have integrated their systems with NavIC and Bhuvan while using bandwidth provided by ISRO.

Bhuvan portal: It is a particular kind of web portal, developed by ISRO, used to locate and gain access to geographical information (geospatial information) and related geographic services (display, modification, analysis, etc.) online.

Every locomotive is equipped with a gadget and a SIM card that broadcasts the train's precise location to a satellite and allows for feedback. A three-second update is made to the movement.
When it's necessary to determine a train's precise location to provide assistance in the event of an accident, flood, or landslide, real-time rail tracking can be helpful.

About Navigation with Indian Constellation (NavIC):

ISRO has established a regional navigation satellite system to meet the positioning, navigation and timing requirements of the nation
ISRO has established the constellation of 7 satellites operating 24*7.
Three satellites of the constellation are placed in geostationary orbit, and four satellites are placed in inclined geosynchronous orbit with equatorial crossing.
NavIC offers two services: Standard Position Service (SPS) for civilian users and Restricted Service (RS) for strategic users.
NavIC coverage area includes India and a region up to 1500 km beyond Indian boundary.
NavIC signals are designed to provide user position accuracy better than 20m and timing accuracy better than 50ns.
NavIC SPS signals are interoperable with the other global navigation satellite system (GNSS) signalsnamely GPS,Glonass,Galileo, and BeiDou
