“…Three reference frames have been designed for the simulations implemented in GMAT and MATLAB: the Earth inertial frame MJ2000Eq to define the mothership motion around the planet (Fig. 2a) [5]; radial in-track cross-track (RIC) centred in the mothership (Fig. 2a) and the CubeSat body frame to describe its relative orbit (Fig.…”

Abstract. In the last few years the number of orbiting satellites has increased exponentially, in particular due to the development of the New Space Economy. Even if this phenomenon makes the space more accessible, bringing a great contribution to the scientific, economic and technological fields, on the other hand it contributes to the overpopulation of the space background. Therefore, it is necessary to develop new techniques to manage the space environment, such as in orbit servicing, which is a procedure that aims to refuel and repair satellites to extend their operational life. A first step to reach this goal is to inspect closely the object of interest to study its features. In this framework, the Space Rider Observer Cube (SROC) mission is being developed. SROC is a payload that will be deployed by Space Rider, an uncrewed and reusable robotic spacecraft designed by ESA. SROC is a 12U CubeSat, whose goal is to carry out inspection manoeuvres around the mothership, then re-enter on board using a safe docking system to come back to Earth. The feasibility of a mission similar to SROC has been simulated during a university class, starting from the definition of the system requirements with particular focus on the analysis of the payloads and subsystems, to ensure the achievement of the mission goals. In particular, the CubeSat is equipped with an optical instrument to capture high resolution images of Space Rider surface and a docking mechanism. Then the design of the orbit and the simulation of the effects of the space environment on the CubeSat have been studied using GMAT, SYSTEMA, MATLAB and other numerical tools. The results of the study are useful for future missions, aiming to inspect orbiting objects, such as operative satellites for in orbit servicing, space debris and dead satellites to study their geometries and plan their removal.
