“…Then the cameras obtain information and data from the above satellites, thus avoiding space collisions and conducting autonomous sensing and detection of in-orbit threats for avoidance or countermeasures. In regard to extraterrestrial planet detection, there are many intelligent SWaP 3 IRCs developed for rover systems applying for exploration of Mars, the Moon, etc., which usually undertake tasks such as surface environment detection and analysis of planets [11,55,56].…”

With the development of infrared detection and imaging technology, infrared cameras (IRCs) play an important role in many fields, such as military, industry, and civilian. Additionally, the requirements for the size, performance, and intelligence of IRCs are becoming more and more strict. Consequently, the associated research and development (R&D) of IRCs is gradually focused on the aspects of miniaturization, high performance, intelligence, low power consumption, and low cost, involving many frontier fields, including artificial intelligence, new materials, new optical systems, and electronics systems. In fact, there are continual studies on intelligent SWaP3 IRCs, but unfortunately, a systematic arrangement and analysis are lacking. Therefore, a systematical and comprehensive review for the developments and core technologies of the intelligent SWaP3 IRCs is really needed. In this paper, in terms of the aforementioned requirements, we conduct a review and analysis of current intelligent SWaP3 IRCs based on 90 literature and statistics in recent decades to provide the relevant developers with a helpful reference for facilitating the indicator optimization of intelligent SWaP3 IRCs with new developed technologies. We analyze the development of SWaP3 IRCs in the aspects of lightweight, miniaturization, low price, and high performance, including hyperspectral resolution, high spatial resolution, large field of view (FOV), and wide dynamic elaborately. Moreover, the development in low power consumption and intelligence is also discussed in detail. Additionally, we briefly summarize the primary applications of intelligent SWaP3 IRCs in military, scientific, and civil. Then, the core technologies comprising high-integration, lightweight, hyperspectral imaging (HSI), low-power consumption, as well as the realization of high performance such as high-resolution, high-frame, and wide-dynamic range of SWaP3 IRCs are discussed and analyzed in detail. Finally, we prospect for the intelligent SWaP3 IRCs that it is necessary to continuously expand the concept of SWaP3 by reliability, stability, extensibility, and safety. In addition, it is useful to embed cutting-edge technologies such as small pixel pitch array, multi-sensors fusion, and deploy intelligent algorithms to IRCs. Additionally, the improvement of the whole machine from multi-dimension such as chip, camera, and system is expected and needs to be taken more seriously. It is hoped that this paper can provide a reference for the R&D of intelligent SWaP3 IRCs in the future.

“…However, only a few small-spacecraft mission concepts can be found in literature leveraging autonomous deep-space navigation-although none of which has yet been funded for implementation-namely: the SRMSAT-2 86-kg small-spacecraft study to orbit the Moon [26,27], the BIRDY 3U CubeSat study on a transfer trajectory to Mars [28], the DustCube 3U CubeSat mission proposal to the Didymos binary asteroid system [29], the LOGIC-X 12U CubeSat mission proposal in close proximity to an asteroid [30], and the LUMIO 12U CubeSat study around the Earth-Moon second Lagrange point [31].…”

Recent advancements in CubeSat technology unfold new mission ideas and the opportunity to lower the cost of space exploration. Ground operations costs for interplanetary CubeSats, however, still represent a challenge towards low-cost CubeSat missions: hence, certain levels of autonomy are desirable. The feasibility of autonomous asteroid flyby missions using CubeSats is assessed here, and an effective strategy for autonomous operations is proposed. The navigation strategy is composed of observations of the Sun, visible planets, and the target asteroid, whereas the guidance strategy is composed of two optimally-timed trajectory correction maneuvers. A Monte Carlo analysis is performed to understand the flyby accuracies that can be achieved by autonomous CubeSats, in consideration of errors and uncertainties in: (a) departure conditions, (b) propulsive maneuvers, (c) observations, and (d) asteroid ephemerides. Flyby accuracies better than ±100 km (3σ) are found possible, and main limiting factors to autonomous missions are identified, namely: (a) on-board asteroid visibility time (Vlim≥11), (b) ΔV for correction maneuvers (>15 m/s), (c) asteroid ephemeris uncertainty (<1000 km), and (d) short duration of transfer to asteroid. Ultimately, this study assesses the readiness level of current CubeSat technology to autonomously flyby near-Earth asteroids, in consideration of realistic system specifications, errors and uncertainties.

“…The growing interest in the development of highly capable nanosatellites for a wide range of scientific missions [1][2][3][4][5] demands a substantial increase of the traditionally low success rate of this kind of miniaturized platforms, which were originally conceived for educational or technological demonstration purposes. Among the causes for their low success rate, the limited ground verification process, especially at sub-system and system levels, is a relevant one, often originating due to schedule and budget constraints.…”

A Dynamic Testbed for Nanosatellites Attitude Verification

To enable a reliable verification of attitude determination and control systems for nanosatellites, the environment of low Earth orbits with almost disturbance-free rotational dynamics must be simulated. This work describes the design solutions adopted for developing a dynamic nanosatellite attitude simulator testbed at the University of Bologna. The facility integrates several subsystems, including: (i) an air-bearing three degree of freedom platform, with automatic balancing system, (ii) a Helmholtz cage for geomagnetic field simulation, (iii) a Sun simulator, and (iv) a metrology vision system for ground-truth attitude generation. Apart from the commercial off-the-shelf Helmholtz cage, the other subsystems required substantial development efforts. The main purpose of this manuscript is to offer some cost-effective solutions for their in-house development, and to show through experimental verification that adequate performances can be achieved. The proposed approach may thus be preferred to the procurement of turn-key solutions, when required by budget constraints. The main outcome of the commissioning phase of the facility are: a residual disturbance torque affecting the air bearing platform of less than 5 × 10 −5 Nm, an attitude determination rms accuracy of the vision system of 10 arcmin, and divergence of the Sun simulator light beam of less than 0.5 • in a 35 cm diameter area.
