This paper proposes a roadmap to address present and future needs in space systems with RISC-V processors. RISC-V is an open and modular instruction set architecture, which is rapidly growing in popularity in terrestrial applications. To satisfy different applications with contrasting requirements in satellite data systems, four different types of processors are identified: 1) low-area/low-power microcontrollers, 2) on-board computers, 3) general-purpose processors for payloads, and 4) enhanced payload processors for artificial intelligence. Several solutions based on RISC-V are proposed for each of these types of processors and compared with proprietary commercial-off-the-shelf and spacegrade solutions. An extensive analysis of the results available from literature is conducted to show that RISC-V has the potential to solve such a wide range of needs. This paper will also show the unprecedented number of open-source implementations and models that were developed in a relative short time on a single instruction set architecture. Future space systems could benefit from many of those developments, and this work identifies and highlights what is still missing to satisfy the specific needs of processors for space, especially in terms of fault tolerance and technology readiness level.

“…A literature search revealed that anchors and even circumferential ropes have been briefly proposed for tying mining equipment to asteroid surfaces [7,8]. However, anchors may be ineffective because all asteroids that have been observed at close range are covered by meters of strengthless regolith [6,9], in which case the anchor pull-out capacity is dependent on the weight of the overlying material.…”

The paper presents an autonomous navigation method for a spacecraft formation flying in the proximity of an asteroid. The measurements from an onboard high resolution camera and a LIDAR are used to estimate the relative position and velocity of the spacecraft with respect to the asteroid. The main innovation is the inclusion of inter-spacecraft measurements provided by the same sensors to evaluate the improvement of navigation performance. Several schemes are constructed to quantify the navigation performance affected by different combinations of measurements, which are obtained from each spacecraft within a 2-spacecraft formation. Unscented Kalman Filter (UKF) is then proposed to simultaneously estimate the position and velocity of each spacecraft with respect to the asteroid. Some examples demonstrate that a significant improvement of the navigation accuracy can be obtained by fusing the inter-spacecraft measurements with the spacecraft-to-asteroid measurements. The robustness of the proposed navigation strategy is then assessed by considering a range of different magnitudes of the noise in measurements and process
