Ground testing of space technologies, and in particular space robotics and Guidance Navigation and Control (GNC) ones, is crucial in order to de-risk space missions that heavily rely on them. In this context, this paper describes the role of the platform-art© robotic facility located at GMV premises in Tres Cantos (Madrid, Spain) as last on-ground validation step within the development and...

This paper describes the design and the parameter identification procedure of a modular spacecraft robotic arm that combined with appropriate ancillary equipment (base-spacecraft, target and end-effector) provides an experimental set-up where control approaches and whole mission scenarios (e.g. servicing and debris removal) can be validated and demonstrated.
The originality of the here...

Euclid is a cosmology mission dedicated to study the geometry and the nature of the Dark Universe with unprecedented accuracy. Euclid will observe a 15000 deg^2 wide area of the sky from the Lagrange point L2 of the Sun-Earth system. The scientific goals of the mission result in very demanding performances for the AOCS subsystem; as an example, the observations’ Relative Pointing Error shall...

Oral presentation at the conference
The set-up and use of ground validation testing facilities from the early phases of the missions can provide a very valuable feedback to the equipment and technologies being developed. The validation activities of the own ground testing facilities are key to the usability and confidence of the results obtained from them. GMV’s platform-art dynamic test bench has already been validated (for...

The problem of uncertainty propagation represents a crucial issue in spaceflight dynamics since all practical systems - from vehicle navigation to orbit determination or target tracking - involve nonlinearities of one kind or another. One topic of recent interest concerns for instance, the space surveillance and the accurate propagation of uncertainties on the initial conditions of resident...

IXV (Intermediate eXperimental Vehicle) re-entry vehicle has successfully flown a fully autonomous mission from the launch until it’s splashdown in the eastern Pacific Ocean on 11th February 2015, and has been regarded as a major milestone in European re-entry technology roadmap. The vehicle has been designed to fly autonomously without the commanding from ground and without a need for a...
