The use of space-based Automatic Dependent Surveillance-Broadcast (ADS-B) receivers to extend aircraft surveillance beyond line-of-sight communication has been discussed since the late 2000s and has been demonstrated in various missions.Although recent demonstrations have relied on small CubeSat platforms, the use of the smallest possible form factor has not been explored. This paper describes development of a spacecraft representing the first use of a 1 U CubeSat platform for aircraft tracking. To comply with the platform's limited power budget, the receiver departs from the typical application of FPGA boards to decoding ADS-B signals and instead employs a general microprocessor. The spacecraft also features some innovations over traditional CubeSat platforms, such as distributed system-level software amenable to extensive code reuse, redundant communications mechanisms, and software-based radiation mitigation strategies. Having designed, built, and integrated all subsystems, as well as performed multiple test campaigns at system and subsystem level, the team now aims at completing formal functional and environmental testing before undergoing the launch campaign, foreseen for 2022.

As a commercial aerospace education satellite, “Ladybeetle-I” has flashed many times around the world, which has attracted the attention of many astronomers. This manuscript presents the design of the beacon lamp of this satellite. Consider the limitation of low power consumption, small volume and light weight of “Ladybeetle-I”, this beacon lamp is designed by the combination of light emitting diode (LED) array structure and total internal reflection (TIR) lens. Firstly, through the analysis of structure parameters, color temperature and working state of LED, the light source of the beacon lamp is realized. Secondly, through the analysis of the requirements parameter of TIR lens, the lens of the beacon lamp is realized. This beacon lamp realizes that the “Ladybeetle-I” in the 547-km LEO can be directly observed by naked eyes within the radius of more than 25 km. Furthermore, the satellite in-orbit test results show that the brightness of the beacon lamp at Sub-Satellite Point is higher than -0.6 magnitude (m) stars. To the best of our knowledge, “Ladybeetle-I”, which utilizes this beacon lamp, is the first and only LEO satellite that can be directly observed by naked eye.
