“…They are considerably smaller than typical commercial satellites, with a volume of 10 cm 3 for a standard size of 1 unit (1U) and a mass of less than 1.33 kg, and they typically use commercial off-the-shelf components [1]. Recently, CubeSats have been advocated for not only by academia [2][3][4] but also by space agencies [5] and industries [6,7] around the world as a means of achieving increasingly complex missions, including scientific, surveillance, and technology demonstration missions. Their advantages include their lower cost, shorter development time, and the opportunity to provide educational experience through hands-on experience.…”

The ability to produce sufficient power is an important factor in assuring the success of the challenging and complex cube satellite (CubeSat) missions within an extremely small size. A CubeSat has only a limited surface area on which solar panels can be installed to generate power. The incidence angle of sunlight on the solar panels also varies according to the revolution and rotation of the satellite. These are important parameters for determining the amount of power that a CubeSat can generate. In this study, we propose a concentrating photovoltaic system for CubeSats that enhances the efficiency of power generation by effectively concentrating the solar energy on the solar panels by using a multi-array lens system under the worst condition for sun incidence angle. The feasibility of using the concentrating photovoltaic system for CubeSat applications is demonstrated by power measurement tests using a solar simulator and a commercial multi-array lens under various light source angles.

“…Among the active small satellite initiatives, ESA's 3U CubeSat OPS-SAT encompasses a dedicated FDIR computer which monitors each payload board through a modular controller [25]. Apart from the ability to monitor houskeeping data coming from the OBC and reacting to a small set of telemetry commands, the 300 FDIR computer is able to circumvent Single Event effects (i.e.…”

Despite their limited lifespan and reduced cost, nano-satellite missions have proved to be suitable platforms for Earth observation, scientific experiments and technology demonstration. During the last years, the number of nanosatellite missions has noticeably increased, posing the need to improve several system characteristics to ultimately endorse the full potential of this class of spacecraft. In this context, this paper presents three design guidelines that can be applied in nano-satellite software in order to improve the system robustness, modularity and autonomy. The design guidelines presented in this paper, namely, hierarchy-enabled robustness, payload-oriented modularity, and on-board planning capabilities, are complemented with a structured review of complementary software techniques and architectural concepts that have been found in the literature. The paper justifies that these system-wide qualities are some of the most critical when designing flight software for CubeSat-like spacecraft and explores how they can improve mission performances and operability, enhance the system's tolerance to failures and ease the development cycles. Finally, this paper illustrates the application of the design guidelines by detailing the on-board software architecture for the 3 Cat-1, a CubeSat program carried out at the Nano-Satellite and Payload Laboratory of the Technical University of Catalonia (UPC BarcelonaTech).

“…On-board processing can be a solution for overcoming the downlink bottleneck for hyperspectral imaging satellites. Although it lacks both a hyperspectral imager and a specific scientific remote sensing mission, the OPS-SAT satellite is a demonstration of the potential for on-board processing in general [18], including image processing and machine learning models trained on-board the satellite after launch. The algorithms tested on OPS-Sat could in principle be adapted to run on larger satellite systems, such as CHIME.…”

“…Although it is yet to be launched, the Intuition-1 mission will develop a small satellite, a 6U CubeSat, to be a testbed for various Artificial Intelligence (AI) algorithms for hyperspectral data processing [29]. The previously mentioned OPS-SAT has received many updates to its software in the years since its launch [18,27].…”

Robust and Reconfigurable On-Board Processing for a Hyperspectral Imaging Small Satellite

Hyperspectral imaging is a powerful remote sensing technology, but its use in space is limited by the large volume of data it produces, which leads to a downlink bottleneck. Therefore, most payloads to date have been oriented towards demonstrating the scientific usefulness of hyperspectral data sporadically over diverse areas rather than detailed monitoring of spatio-spectral dynamics. The key to overcoming the data bandwidth limitation is to process the data on-board the satellite prior to downlink. In this article, the design, implementation, and in-flight demonstration of the on-board processing pipeline of the HYPSO-1 cube-satellite are presented. The pipeline provides not only flexible image processing but also reliability and resilience, characterized by robust booting and updating procedures. The processing time and compression rate of the simplest pipeline, which includes capturing, binning, and compressing the image, are analyzed in detail. Based on these analyses, the implications of the pipeline performance on HYPSO-1’s mission are discussed.
