Advancements in spectral sensor technology and nanosatellites have opened up new possibilities for remote sensing applications, particularly in geological mapping, mining exploration, and environmental monitoring. Hyperspectral imaging, which combines digital imaging and spectroscopy, has garnered significant interest due to its ability to capture radiation across many contiguous and narrow spectral bands, providing detailed information about a scene of interest. This technology covers a broad spectral range, including the infrared range between 3 μm to 5 μm and 8 μm to 12 μm, and provides more complete information compared to other satellite imaging technologies. Nanosatellites currently offer low-cost opportunities for earth exploration missions for mining and energy resources using compact imagers. To meet mining exploration needs, the study proposes to use hyperspectral payloads embedded on CubeSat-class satellites. The aim is to define technical specifications required for the mining sector, then to synthesize the characteristics of different compact hyperspectral sensors and select a payload that can be embarked on board nanosatellites to explore mineral resources. Finally, the study investigates the feasibility of using a compact hyperspectral camera for imaging applications designed for CubeSat platforms, the challenges associated with its use, and the preliminary results of the mission analysis using Systems Tool Kit (STK) software package. To conclude, while the study was focused on the mission aspects of hyperspectral imaging, such as orbit design and ground coverage, it still demonstrated that a nanosatellite-based hyperspectral mission can yield valuable information for mineral resource exploration while mitigating the costs and risks associated with other missions.
