Abstract	Accurate preflight testing environments for formation flying are crucial in transitioning between numerical simulation and actual orbital flight. A 3 degree of freedom (DOF) experimental testbed was developed at the Advanced Autonomous Multiple Spacecraft (ADAMUS) laboratory to validate a relative orbit elements-based control strategy for satellite formation reconfiguration maneuvering. The experimental facility consists of two completely autonomous vehicles floating on an epoxy 4×4 m surface. The vehicles are equipped with compressed air thrusters to enable their movement on the frictionless floor while a PhaseSpace Impulse System determines their position and attitude. A numerical simulator describing the dynamics of the testbed was developed, using MATLAB and Simulink, to have a benchmark for cross checking experimental results. This paper presents the design and integration of the vehicles with their preliminary experimental results. An experiment based on an analytical control scheme of 3 tangential (T-T-T) finite-time maneuvers was conducted to generate a guidance. A feedback control law using a Linear Quadratic Regulator (LQR) was implemented to follow the guidance. The vehicle was able to accurately track a computed guidance trajectory within the accuracy of 0.06 m.
