The Sharjah-Sat-1 3U CubeSat is designed and realized together with the Sharjah Academy for Astronomy, Space Sciences, and Technology (SAASST), the University of Sharjah (UoS), Istanbul Technical University (ITU), and Sabanci University (SU). It has two scientific objectives: performing X-ray astronomy observations and capturing remote sensing and Earth observation images of the United Arab Emirates. The CubeSat is to be launched by the fourth quarter of 2022 and is currently in the Flight-Model integration phase. The primary science payload is the iXRD (Improved X-Ray Detector), with the main objective of observing very bright transient and persistent galactic hard X-ray sources. It will use a pixelated 5 mm CdZnTe-based crystal as an active material with an energy range of 25keV to 300keV and a spectral resolution between 5-10 keV at 60keV, depending on the pixel size. In addition, a Tungsten collimator with a field of view of 4.26 degrees and a tungsten shield at the back decreases the cosmic X-ray and Earth's albedo background. Its' second objective is solar observations to study the hard X-ray spectra of flares and coronal holes. Other potential targets are transient bright events (e.g., GRBs and magnetar bursts). This presentation will show the results of laboratory calibration, TVAC tests, and sensitivity analysis based on in-orbit background simulations to support its science objectives.
