ELROI光学卫星牌照首次在轨飞行
The First Orbital Flight of the ELROI Optical Satellite License Plate
摘要：
空间物体识别是空间交通管制的基石之一，也是航天器成功运行的必要条件。ELROI，即极低资源光学标识符，是一个新概念，可以在厚邮票大小的包裹中提供自供电的卫星识别信标。其体积小、成本低和完全自主运行使其可用于所有空间物体，包括立方体卫星和惰性碎片物体。信标的信号是在地面上用一个装有光子计数探测器的小型望远镜接收的，该探测器可以在一次经过头顶时明确地确定卫星的识别号。信号中还可以包括其他信息，以帮助诊断和解决异常情况，进一步提高航天飞行的可靠性和安全性。轨道上的第一个ELROI单元于2018年12月发射，作为学生CubeSat NMTSat的有效载荷。我们正在寻找识别信号。
英文摘要：
Space Object Identification is one of the cornerstones of Space Traffic Control and a requirement for successful operation of a spacecraft. ELROI, the Extremely Low Resource Optical Identifier, is a new concept that can provide a self-powered satellite identification beacon in a package the size of a thick postage stamp. Its small size, low cost, and fully autonomous operation make it usable by all space objects, including CubeSats and inert debris objects. The beacon's signal is received on the ground using a small telescope equipped with a photon-counting detector which can unambiguously determine the satellite identification number during a single pass overhead. Additional information can be included in the signal to aid in anomaly diagnosis and resolution, further improving spaceflight reliability and safety. The first ELROI unit in orbit was launched December, 2018 as a payload on the student CubeSat NMTSat. We are now searching for the identification signal.
