As the primary mission of ROCSAT-1 is to carry out scientific research, the satellite will carry three scientific instrument "payloads": the Ocean Color Imager, the Experimental Communication Payload and the Ionospheric Plasma and Electrodynamics Instrument (also called the Solar Terrestrial Physics Instrument).
由於一號衛星的應用任務是以科學研究為主，所以上面會設備三項科學實驗儀器（衛星術語謂之酬載）：海洋水色照相儀、通訊實驗酬載和電離層電漿電動效應儀（又叫日地物理效應儀）。
