It can find and sense objects from an enormous distance, "relates Chen Liang-chien." There is an optical sensing device on the resource satellite. Like the human eye, it records objects 'reflection and absorption of light. This record is then sent to the surface where it is turned into images. "
「顧名思義，遙感探測就是不直接接觸物體，而從遠處探測，感知物體」，陳良健解釋說，「資源衛星上有個光學感測器，就像人眼一樣，能記錄物體對太陽光不同的反射和吸收光譜，再把資訊傳輸到地面，組合成影像。」
