In recent years, there is a growing interest in small satellites for deep space exploration. The
current approach for planetary navigation is based on ground-based radiometric tracking. A …

CUBESATS are low-cost platforms to test innovative technologies in-flight that also allow
performing science [1]. Adopting CubeSats is appealing due to the inherent savings in the …

The Lunar Meteoroid Impacts Observer, or LUMIO, is a space mission concept awarded
winner of ESA's SysNova Competition “Lunar CubeSats for Exploration,” and as such it is …

Abstract Line-of-Sight (LoS) navigation is an optical navigation technique that exploits the
direction to visible celestial bodies, obtained from an onboard imaging system, to estimate …

The increasing number of deep-space missions and the consequent saturation of the Deep-
Space Network navigation slots has sparked the interest in autonomous navigation …

Abstract The Lunar Meteoroid Impact Observer (LUMIO) is one of the four projects selected
within ESA's SysNova competition to develop a small satellite for scientific and technology …

This paper presents a reinforcement-learning (RL)-based robust low-thrust guidance
method for asteroid approaching under process uncertainties. Markov decision processes …

The momentum taken by the space sector in the exploration of our Moon pushes private and
governmental actors to intensify their efforts for launching missions to our natural satellite. In …

1 payload data is also described to cope with the limited contact time and downlink
bandwidth. Since all communications have to go via a Lunar Orbiter (mothership), all …

The latest space missions have unveiled GNSS usability for distances greater than 187 000
km from the Earth's surface. The actual availability and usability of GNSS signals beyond …
