Georgios Salavasidis

Georgios is a Robocademy ITN Early Stage Researcher at National Oceanographic Institute (NOC), Ocean Technology and Engineering. His main area of research is long range Unmanned Underwater Vehicles (UUVs) navigation with low power. He graduated from the Department of Electrical and Computer Engineering of Polytechnic School, Democritus University of Thrace, Greece, in September 2013. He pursued his diploma thesis on autonomous design trajectories system of underwater teams of robots for mapping of unknown and GPS-denied environments. He worked for 1.5 years as research assistant at Center for Research and Technology – Hellas (CERTH) mainly on the autonomous, self-Learning, OPTImal and complete Underwater Systems (NOPTILUS) project. In the spare time, he likes playing tennis and basketball.

Project Description: His main objective is the development of efficient navigation techniques of both autonomous underwater vehicles (AUVs) and surface marine vehicles (ASVs) for long range missions constrained by limited available energy. The navigation challenge will be considered in two different scenarios. Initially, navigation methodologies for the open water case seen will be developed utilizing an ASV (as an acoustic tether) and low resolution maps for error reduction in the AUV’s dead reckoning navigation. In the more complex scenario - navigation beneath the arctic ice cap (GPS-denied environment and low level accuracy of both magnetic and laser gyro heading sensor), a multifaceted navigation approach will be developed combining, optimally, many navigational aids towards minimizing AUV power requirement and operational cost while keeping the navigational accuracy in high level.
