- The system enables swift electronic data transfer between mobile vessels and shore (base stations) through advance and real-time exchange of information so as to ensure navigation safety in inland waterways.
- It also provides virtual navigational aids to guide the vessel during navigation.

- Most fishways enable fish to pass around the barriers by swimming into the waters on the other side.
About Hilsa Fish
- Hilsa has a history of migrating to Allahabad in the Ganga river system from Bangladesh.
- It is Bangladesh’s national fish and was called Matsyaraja – the king of fishes.
- Though it’s a saltwater fish, it migrates to sweet waters of the Ganges from the Bay of Bengal.
- It travels upstream of the river during the mating seasons and returns to its natural abode after spawning.
