The Nautex project is intended as an experimental phase aimed at demonstrating the feasibility of a national navigation system, the Naute system (NAvigation by Use of Established Trajectories), based on a drag-free satellite. After a general presentation of the project, the work done at ONERA, in cooperation with CNES (the French Space Agency), is described with a view to defining a last draft of the drag-free satellite piloting system. The main characteristics of a position detector derived from the Cactus accelerometer are optimized from the results of internal perturbation evaluations, taking into account the chracteristics of the motors ensuring the piloting. The piloting law was studied for the operational phase, with drag compensation, and for that during which the proof mass of the position detector is acquired.
