In this paper a nonlinear controller technique, referred to State-Dependent Riccati Equation (SDRE), is exploited to handle relative position tracking and attitude synchronization problem involving in docking manoeuvring operations between two Earth orbiting satellites. More specifically a testbed developed by DLR-Institute of Space Systems is used for testing the proposed control algorithm. The experimental results show the effectiveness of SDRE controller for proximity operations problem and its feasibility for real-time implementation on the hardware.
