Research Contract to Politecnico di Milano

On Friday September 7th, 2007 TEK4VALUE signed a research contract with the Politecnico di Milano - Dipartimento di Elettronica e Informazione for the "Analysis and Development of algorithm for the attitude estimation of maritime vehicles".

This research activity is synergic to the TEK4VALUE activity for MARINE sector and aims to increase the robustness and accuracy of the heading real-time estimate provided by an on-board single antenna Inertial Navigation System onto large vessels.

The classical approach for the vessels heading estimation requires two GPS antenna separated few meters, making the system scarcely portable, difficult to install and calibrate. The use of the single antenna configuration greatly increase the portability of the system but may introduce instabilities in the heading estimate.

The adopted INS is endowed with an Inertial Measurement Units (three MEMS gyro and three accelerometer) a RTK GNSS receiver with a single antenna and an Extended Kalman Filter for the data fusion and filtering.

The research shall demonstrate the feasibility of the approach and develop the algorithm to augment the EKF capabilities and robustness. The algorithm will be installed into a portable unit and demonstrated on actual vessels.
