The surge of deep-space probes makes it unsustainable to navigate them with standard radiometric tracking. Autonomous interplanetary satellites represent a solution to this problem. In this work, a vision-based navigation algorithm is built by combining an orbit determination method with an image processing pipeline suitable for interplanetary tran...

The number of spacecraft launched per year is increased dramatically in the last decades granting access to private companies and public actors. Space assets are becoming crucial to asses disaster monitoring, precise agriculture, and global network interconnections. This trend is not limited to Earth observation applications, but it extends beyond...

A new era of space exploration and exploitation is fast approaching. A multitude of spacecraft will flow in the future decades under the propulsive momentum of the new space economy. Yet, the flourishing proliferation of deep-space assets will make it unsustainable to pilot them from ground with standard radiometric tracking. The adoption of autono...

In the last decade, the new space economy has underlined the importance of the space sector for public and private actors. Advances in CubeSats technologies allowed widespread access to large and small businesses, with private companies and undersized players benefitting from the reduced development, manufacturing, and launch costs. As a result, th...

A new era of space exploitation is fast approaching. An exponential number of CubeSats, shoe-boxed spacecraft, will be launched into space, owing to their low cost compared to traditional probes. At the current pace, piloting CubeSats from the ground with standard radiometric tracking will become unsustainable. This work tackles the problem from th...

In this work, an orbit determination algorithm suitable for CubeSats onboard implementation is developed, which simulates optical autonomous navigation accomplished by a stand-alone platform. An extended Kalman filter featuring line-of-sight acquisitions of planets is selected as the state estimator, and its performances are tested on a Raspberry P...

The adoption of CubeSats marks the beginning of new momentum in interplanetary exploration, owing to their low cost as compared to standard missions. Yet, the proliferation of deep-space CubeSats will cause the saturation of the ground networks, hindering the traditional navigation through ground-based radiometric tracking. The solution to this iss...

A new era of space exploitation is fast approaching. CubeSats have performed a revolution in the way satellites are deployed in interplanetary missions. The exploitation of standardized dimensions and Commercial-Off-The-Shelf components has boosted their utilization by reducing mission costs and development time. The cutting down on the space entry...

A new space era is fast approaching. In this decade, CubeSats have granted affordable access to space due to their reduced manufacturing costs compared to traditional missions. Although most of miniaturized spacecraft has thus far been deployed into near-Earth orbits, soon a multitude of CubeSats will be employed for deep-space missions as well. By...

The proliferation of deep-space probes is posing new challenges in navigating them with ground-in-the-loop methods. Ground tracking stations will reach saturation owing to the escalation of small satellites in deep space. Thus, autonomous guidance, navigation, and control methods that are independent from ground communications are necessary for fut...
