“…In particular, there are significant examples of CubeSat technologies being tested through stratospheric launches of High-Altitude Balloons (HABs) and suborbital sounding rockets. These tests are typically targeted at confirming the "technology readiness" of the system by simulating conditions that are similar to space in Earth's upper atmosphere [61]. CubeSat testing programs organized by the European Space Agency (ESA) that are specifically intended for college students include BEXUS (Balloon EXperiments for University Students) [62] and REXUS (Rocket Experiments for University Students) [63] A comprehensive analysis of terrestrial testing of CubeSat systems is beyond the scope of this review, but a few examples include testing a Software-Defined Radio (SDR) communication architecture [64], the measurement of magnetic field disturbances [65], or the creation of a heat transfer experiment [66].…”

In recent years, CubeSats have gained popularity as secondary payloads in space missions due to their uniquely small size and minimal weight. This allows for the quick and inexpensive development of high-risk, high-reward investigations. The success of cube-shaped CubeSats has led to the development of a new class of small-scale and low-cost scientific platforms known as CanSats, which maintain a unique cylindrical shape. CanSats offer an even more economical alternative for conducting high-risk investigations, although they are typically constrained by having to operate within Earth’s atmosphere, which contributes to their reduced costs. However, the ability to test and improve space-bound hardware makes the CanSat a potential intermediary technology for continued space exploration. This survey paper seeks to provide a technical definition of CanSats and summarize the current state of the art in CanSat-based research. This paper covers the history of CanSats, their current mainstream applications, and their potential impact on the technology pipeline for space exploration. CanSats have proven to be versatile in various applications, including Earth science, aeronautics, and educational purposes. The lower cost of CanSats provides a wider range of researchers and educational institutions access to near-space science. Therefore, this paper also aims to explore the potential future applications of CanSats, particularly as an intermediary technology for testing and improving space-bound hardware, with potential benefits for future space missions. The findings from this survey could help to guide the further research and development of CanSats, as well as help to shape future space exploration efforts.

This study introduces a robust model-based framework designed for the verification and validation (V&V) of Attitude Determination and Control Systems (ADCSs) in nanosatellites, focusing on magnetic actuation while still being applicable to larger spacecraft platforms. By employing Model-in-the-Loop (MIL), Software-in-the-Loop (SIL), Processor-in-the-Loop (PIL), and Hardware-in-the-Loop (HIL) methodologies, this framework enables a thorough and systematic approach to testing and validation. The framework facilitates the assessment of long-term maneuvers, addressing challenges such as initial small-attitude errors and restricted 3D movements. Two specific maneuvers are evaluated: detumbling and nadir pointing, utilizing quaternions and a comprehensive suite of sensors, including six sun sensors, a three-axis magnetometer, a three-axis gyroscope, GPS, and three magnetorquers. The methodologies—MIL, SIL, PIL, and HIL—integrate the behaviors of digital sensors, analog signals, and astrodynamic perturbations. Based on an optimized SIL environment, Monte Carlo simulations were performed to optimize control gains for nadir pointing, achieving a mean pointing accuracy of 11.69° (MIL) and 18.22° (PIL), and an angular velocity norm of 0.0022 rad/s for detumbling. The HIL environment demonstrated a mean pointing accuracy of 9.96° and an angular velocity norm of 0.0024 rad/s. This comprehensive framework significantly advances the design and verification processes for nanosatellite ADCSs, enhancing the reliability and performance of nanosatellite missions.
