In future precision agriculture, it is expected that each plant will get coordinates with very high accuracy. The type of plants and their coordinates will be stored in a database with additional agricultural information. Therefore, the farming tools have to be coordinated with high accuracy in the relevant navigation reference frame. On the tractor usually a dual frequency multi-system professional GNSS receiver with differential corrections is used (e.g. RTK, PPP, N-RTK, etc..). In order to avoid the cost for an additional high end package for the each farming tool, it is possible to determine coordinates by a lever arm solution, e.g. determining the transfer attitude (transfer alignment) by an integration of visual and inertial sensors and gyro based system making use of the known linear dimensions of the farming tool. Because the drawbar has a certain tolerance in the trailer hitch, an additional distance sensor (laser, ultra-sound) must be implemented. The problem is applicable to other land machines, and more generally, to machine control (e.g. civil works) or to constrain and steer large mechanical ensemble (e.g. machinery in civil works or even for satellites). The objective of the activity is to develop a relative high precision PNT-Attitude determination and transfer alignment system to determine each point of a mechanical ensemble. The study will define a generic model for the use of sensor fusion in the control of a mechanical ensemble and then tailor it and demonstrate an extremely accurate solution for Precision Agriculture (seeder comb with accuracy in the range of 5 mm).
