USV- Paresh was recently designed by the Department of WR and OE jointly with Center for System Design (CSD), NITK Surathkal. A similar USV costs up to Rs 4 crore, but the institute has developed it for Rs 15 lakh using open source resources. The team working on the project included Prithviraj U, Assistant Professor, KV Gangadharan, Coordinator, CSD, Rakshit Kotian, Steven Lloyd and Rajath C Kotekar, Junior Research Fellow, CSD.
Prithviraj U, Assistant Professor, WR and OE, said that Deka was an eminent researcher in the field of bathymetry, and used traditional techniques. Prof. Deka served the world with his longest tenure at NITK, where, until his untimely demise, he taught postgraduate students, mentored many research scholars and authored several textbooks, while in his areas of Hydrology, GIS Mapping, Machinery. Worked on cutting edge research. learning applications and others. “The research work laid by Professor Deka will be continued using the foundation USV Paresh. Hence we have dedicated this USV in his name,” said Prithviraj.
Prof. Deka also assisted the coastal districts of Udupi and Dakshina Kannada in sand block allocation works.
how it works
USVs built on the kayaks are monitored and controlled by an in-house developed ground station system, which processes the data and produces results immediately on site. USV Paresh aims to reduce the need for a human operator. Prithviraj said that it can be used to roam the water bodies. The USV is equipped with a single-beam echo-sounder to measure depth in shallow water. The current system measures distances up to 75 metres, and can be replaced with multi-beam sonar for greater depth. It is powered by a powerful 400W electric motor with a battery backup of six hours. There are outriggers on both sides, which stabilize the ship in rough seas. The USV has a range of 40 km when fully charged, and can be controlled remotely or operated autonomously.
Paresh is equipped with interchangeable payloads such as state-of-the-art differential GPS for centimeter-level positioning accuracy, LiDAR units to integrate bathymetry with topography, water quality monitoring systems, bathymetric soil augers and sample collection.
