We consider a methodology to optimally obtain reconfigurations of spacecraft formations. It is based on the discretization of the time interval in subintervals (called the mesh) and the obtainment of local solutions on ...

To palliate the hazards posed by satellites re-entering the atmosphere, international guidelines have defined a maximum acceptable risk for objects to re-enter uncontrolled. Containment methods attempt to reduce this ...

Cincuenta años después de que el Sputnik sobrevolara la Tierra a menos de 1.000 km de altitud, circunstancia que despertó dosis similares de recelo y admiración, la exploración espacial sigue sustentándose en cohetes que ...

The main objective of this paper is the study of the thermal behaviour of spacecrafts PCB. Specifically, the work is focused on obtaining experimental data of the thermal contact resistance of a spacer in a PCB in therms ...

It is known that the Martian atmosphere contains a large amount of suspended dust. The saltation process, or gravitational settlement of atmospheric dust, onto the surface of solar arrays can affect the utility of solar ...

A MATLAB/Simulink model of the Primary Power Distribution System of a lunar habitat is presented. The model can be adapted to multiple scenarios, and is able to interface with computer models of other habitat subsystems. ...

In the present paper we consider the attitude synchronization problem for a formation of spacecraft flying in free space. In particular, we consider the same control laws of [1] and we expand on the results presented there. ...

Aiming to obtain aerospace vehicle ight parameters and engine characteristics, a DCM and magnetometer fusion algorithm is introduced in addition to a Kalman lter, in order to estimate position, velocity and acceleration ...
