地球观测传感器设计方面的一场技术革命正在发生。这场革命在一定程度上与CubeSat平台的出现有关，这些平台迫使传感器必须安装的体积和功率实现了事实上的标准化。与更大、更昂贵的传感器相比，小型传感器确实可以提供类似或替代能力的程度几乎没有得到证明，较小系统的能力损失与通过更分散的观测战略实施它们所带来的成本收益和新的潜在能力之间的权衡也尚未得到接受。本文提供了四个使用原型小型化观测系统进行观测的例子，其中包括来自CubeSats的观测，这些例子提供了对这场新兴的传感器革命的一瞥，并为未来的观测系统设计提供了提示。
A technology revolution in Earth observation sensor design is occurring. This revolution in part is associated with the emergence of CubeSat platforms that have forced a de facto standardization on the volume and power into which sensors have to fit. The extent that small sensors can indeed provide similar or replacement capabilities compared to larger and more expensive counterparts has barely been demonstrated and any loss of capability of smaller systems weighed against the gains in costs and new potential capabilities offered by implementing them with a more distributed observing strategy also has not yet been embraced. This paper provides four examples of observations made with prototype miniaturized observing systems, including from CubeSats, that offer a glimpse of this emerging sensor revolution and a hint at future observing system design.
