“…This information is transmitted to the On-Board Computer (OBC) that filters it, and then combines it with other data from different sensors (magnetic, Earth’s horizon, etc.) to determine the attitude of the satellite and improve the subsystem’s response [ 7 , 8 , 9 , 10 , 11 ].…”

This paper presents the development of the UPMSat-2 sun sensor, from the design to on-orbit operation. It also includes the testing of the instrument, one of the most important tasks that needs to be performed to operate a sensor with precision. The UPMSat-2 solar sensor has been designed, tested, and manufactured at the Universidad Politécnica de Madrid (UPM) using 3D printing and COTS (photodiodes). The work described in this paper was carried out by students and teachers of the Master in Space Systems (Máster Universitario en Sistemas Espaciales—MUSE). The solar sensor is composed of six photodiodes that are divided into two sets; each set is held and oriented on the satellite by its corresponding support printed in Delrin. The paper describes the choice of components, the electrical diagram, and the manufacture of the supports. The methodology followed to obtain the response curve of each photodiode is simple and inexpensive, as it requires a limited number of instruments and tools. The selected irradiance source was a set of red LEDs and halogen instead of an AM0 spectrum irradiance simulator. Some early results from the UPMSat-2 mission have been analyzed in the present paper. Data from magnetometers and the attitude control system have been used to validate the data obtained from the sun sensor. The results indicate a good performance of the sensors during flight, in accordance with the data from the ground tests.

“…The information is then encoded into messages based on the data communication link format and broadcast automatically. The ADS-B system uses air-ground and air-air data communication to complete information transmission and traffic monitoring (Ali, 2016;Baek et al, 2016;Mangali and Bagmare, 2017;Zhou et al, 2017). ADS-B Out is enforced to maintain surveillance of aviation operations in Australia, China, Europe and the United States.…”

Space-based automatic dependent surveillance-broadcast (ADS-B) receivers can cover thousands of aircraft, each transmitting 6 ⋅ 2 signals per second. As a result, ADS-B signals are very prone to overlap. When the number of aircraft covered by a receiver reaches 3,000, about 90 % of the signals will be overlapping. Overlapped signals can reduce the decoding accuracy of receivers, so that aircraft information cannot be accurately transmitted to the air traffic control (ATC) surveillance system, hence threatening aviation flight safety. It is necessary to propose signal separation algorithms for space-based ADS-B systems. An orthogonal projection linear constrained minimum variance (OPLCMV) algorithm is proposed, which can separate two signals simultaneously based on the linearly constrained minimum variance algorithm by exploiting the characteristics of overlapped signals. Compared with the state-of-the-art extended projection algorithm and the fast independent component analysis algorithm, the OPLCMV method has a higher decoding accuracy for multiple overlapping signals with a small direction difference of arrival or frequency shift. Moreover, the OPLCMV algorithm has a low computational complexity when the number of overlapped signal sources is less than seven.

The determination of the occasion when the low Earth orbit satellite meets the narrow-beam signal is quite important. Based on the orbit prediction model of simplified general perturbations 4 (SGP4), the calculation model of the relative position between the low Earth orbit satellite and the ground target is established in the paper, and so is the calculation model of the relative position between the low Earth orbit satellite and the high Earth orbit communication satellite. The determination method of the occasion when the low Earth orbit satellite meets the narrow-beam signal is further proposed. It is shown by the simulation results that the proposed calculation method possesses high accuracy and feasibility and is able to satisfy the practical application requirements.
