Reusability in the launcher sector has been studied for quite a long time in Europe, but so far, projects have mostly stayed on the drawing-board. Today, players from the so-called \"NewSpace\" demonstrate rocket boosters\' recovery and reusability on a regular basis. The established rocketry industry is being challenged by new space actors and emerging space nations. In this climate of intensifying competition, there is a growing sense of urgency in Europe, a feeling that we need to seize the moment and change our ways, to prove that Europe still possesses the ability to surpass itself. The French Space Agency (CNES) is one of the stakeholders in Europe for future launchers preparation, along with ESA, other national agencies and industry. To catch up as quickly as possible, CNES promotes several initiatives at different scales, whether it be with students, academics, SMEs or big players, aiming at fostering key competencies for reusability in Europe. As a matter of fact, among the required technologies for reusable rockets, GNC (Guidance, Navigation and Control) for landing is deemed to be one of the most challenging ones. This must not be studied only by simulation, but also with tests on demonstrators. Among these studies, FROG corresponds to the early sandbox approach. It is a small scale and low-cost flying vehicle developed as a testbed platform for guidance, navigation, and control algorithms that will be used by CNES Launcher Directorate and students in order to test various landing algorithms and approaches. This paper is the continuation of a first one about FROG presented at IAC 2018 conference held in Bremen [14]. In this paper, we will first quickly introduce the project then describe the common platform which has been developed and finally delve into the GNC aspects. Secondly, we will present the first version of FROG based on a small turbojet, the associated development outcome and also the main flights results. Finally, we will also present the ongoing development of the second version of FROG based on small monopropellant rocket engine. |
