“…Multiple missions have been launched, such as the HYPSO-1 6U CubeSat (10*20*30cm) launched in January of 2022, developed by the Norwegian University of Science and Technology (NTNU). The HYPSO-1 mission utilizes a hyperspectral imager (HSI) which can capture hyperspectral images with a spectral range of 220-967nm with the capability of capturing at least 215 bands with a GSD of better than 100 meters [5]. The Sharjah Academy for Astronomy, Space Sciences, and Technology (SAASST) is currently developing Sharjah-Sat-2, which is a 6U CubeSat with an advanced hyperspectral imager capable of capturing 422 bands.…”

The space sector's rapid growth, coupled with increased accessibility to space, has led to the popularity of miniaturized satellites known as CubeSats. These cost-effective and agile nanosatellites have gained international recognition in government, education, and private sectors. CubeSats, standardized at 10 cm x 10 cm x 10 cm, come in various sizes (1U, 2U, 3U, and 6U) and are preferred by the GIS/RS community for earth observation capabilities. Sharjah Academy for Astronomy, Space Science and Technology (SAASST) in the UAE has established a CubeSat laboratory, launching the Sharjah-Sat-1 (3U+) and now embarking on the Sharjah-Sat-2 mission. Sharjah-Sat-2 is a 6U CubeSat equipped with an advanced high-definition hyperspectral camera, Hyperscape100, to enhance infrastructure projects and establish an early warning system for environmental phenomena. This paper will discuss advancements in spaceborne hyperspectral imagers, compare nanosatellites to larger satellites, highlight the Sharjah-Sat-2 project, and explore its positive impact on the GIS/RS community.

“…The push-broom imaging spectrometer was spectrally and radiometrically calibrated with a calibration procedure based on [39].…”

“…It should be noted here, that the correct radiometric measurements of E d (λ) depends highly on the constant and accurate exposure time, which in turn depends on the clock signal used by the spectrometer. This calibration method is inferior to calibration with an integrating sphere as shown in [39] and is therefore only used for the proof-of-concept shown in this paper.…”

“…This lab supplied an integrating sphere (coated in barium sulfate), calibration lamps (including a certified tungsten halogen lamp and spectral calibration lamps with known spectral emission), and mounting structures for the imagers. HSI calibration [20] was completed using this method, while RGB calibration was performed with spatial targets, such as a checkerboard pattern, in the same lab.…”

Assembly, Integration, and Verification/Testing (AIV or AIT) is a standardized guideline for projects to ensure consistency throughout spacecraft development phases. The goal of establishing such a guideline is to assist in planning and executing a successful mission. While AIV campaigns can help reduce risk, they can also take years to complete and be prohibitively costly for smaller new space programs, such as university CubeSat teams. This manuscript outlines a strategic approach to the traditional space industry AIV campaign through demonstration with a 6U CubeSat mission. The HYPerspectral Smallsat for Ocean observation (HYPSO-1) mission was developed by the Norwegian University of Science and Technology’s (NTNU) SmallSatellite Laboratory in conjunction with NanoAvionics (the platform provider). The approach retains critical milestones of traditional AIV, outlines tailored testing procedures for the custom-built hyperspectral imager, and provides suggestions for faster development. A critical discussion of de-risking and design-driving decisions, such as imager configuration and machining custom parts, highlights the consequences that helped, or alternatively hindered, development timelines. This AIV approach has proven key for HYPSO-1’s success, defining further development within the lab (e.g., already with the second-generation, HYPSO-2), and can be scaled to other small spacecraft programs throughout the new space industry.
