“…Moreover, the diminishing costs of Cube-Sat missions is becoming possible because of the fast technology advancements in microelectronics, coupled with the intense use of COTS components. The miniaturization of sensors and actuators allowed, for instance, the development of attitude determination and control systems for CubeSats (e.g., [28]). Innovations like foldable lightweight optics, solar panels, and antennas will also boost CubeSat usage (e.g., [29][30][31][32]).…”

CubeSats have become an interesting innovation in the space sector. Such platforms are being used for several space applications, such as education, Earth remote sensing, science, and defense. As of May 31st, 2018, 855 CubeSats had been launched. Remote sensing application is the main sector in which CubeSats are being used, corresponding to about 45% of all applications. This fact indicates the commercial potential of such a platform. Fifty eight countries have already been involved with developing CubeSats. The most used CubeSat configuration is 3U (about 64%), followed by 1U (18%), while 6U platforms account for about 4%. In this paper, we present an analysis of the current situation regarding CubeSats worldwide, through the use of a dataset built to encompass information about these satellites. The overall success rate of the CubeSat missions is increasing over time. Moreover, considering CubeSat missions as a Bernoulli experiment, and excluding launch failures, the current success rate was estimated, as a parameter of a binomial distribution, to be about 75%. By using a logistic model and considering that the launchings keep following the current tendency, one can expect that one thousand CubeSats will be launched in 2021, within 95% certainty.

“…Micro-nano satellites' precision and speed requirements for attitude control are directly related to the satellite's scientific missions. For missions with low accuracy requirements, ADCS needs to achieve the pointing accuracy of 2-10° [6,[15][16][17][18] and the control cycle of 0.5-2Hz [15,[18][19]. The satellite attitude determination accuracy and update rate must be higher than the pointing accuracy and the control cycle to meet the satellite's attitude control requirements.…”

To optimize the geomagnetic reference vector and the solar reference vector calculation method, this paper proposes a geomagnetic fitting algorithm and simplifies the DE430 ephemeris structure to speed up the determination rate of the geomagnetic and solar reference vectors. The two optimized reference vector determination methods are simulated on the Attitude Measurement Unit (AMU). The simulation results show that the single-step elapsed time of the geomagnetic fitting algorithm is reduced by 99.5% compared with the IGRF-13 geomagnetic model algorithm, and the data capacity is reduced by 97.3% compared with the look-up table method. The data capacity of the simplified ephemeris algorithm is 66.9% lower than that of the DE430 ephemeris algorithm, and the calculation accuracy is nearly 3 orders of magnitude higher than that of the approximate calculation method. This method can significantly shorten the attitude determination time and increase the attitude determination frequency, dramatically improving attitude determination accuracy and attitude control accuracy. The AMU supported by these two algorithms has sound engineering practical value.

This paper proposes high-accuracy and reliable attitude measurement methods exclusive for CubeSat with restrictions of low cost, limited space, and low power consumption. The attitude measurement unit is equipped with Commercial Off-The-Shelf (COTS) components including Micro-Electro-Mechanical System (MEMS) gyro and two simultaneously operating star trackers (STR) to enhance the measurement accuracy. The Multiplicative Extended Kalman Filter (MEKF) is used to estimate the attitude of CubeSat, and four kinds of attitude estimation layouts are put forward according to the idea of weighted average of two quaternions from two STR and different architectures of information fusion. Using the proposed methods, the attitude measurement unit can continuously provide accurate and reliable attitude knowledge for attitude control unit when the CubeSat is running in orbit. Numerical simulation is performed to verify the effectiveness of the proposed methods, and it offers a reference for CubeSat developers from the perspective of engineering application.
