Sharjah-Sat-2 is a 6U Earth Observation (EO) CubeSat currently being developed by the Sharjah Academy for Astronomy, Space Sciences, and Technology (SAASST) and the University of Sharjah (UoS). The 6U CubeSat is currently being designed and integrated with two payloads on board: (1) a High-Resolution Hyperspectral Imager with less than 5 Meters of Ground Sampling distance (GSD) and (2) an experimental payload consisting of a GNSS receiver. The mission's primary scientific objective is to capture High-Resolution Hyperspectral images of the United Arab Emirates to provide a constant stream of reliable data that can be utilized to improve the country's infrastructure and resource management. The secondary mission objective is to monitor and validate the integrity of GNSS signals received by CubeSat and compare them to calibrated ground based GNSS receivers. This paper will provide insight into the GNSS Payload onboard Sharjah-Sat-2 and how its data could be utilized to measure and validate the signal integrity of the observed GNSS satellites. Also, we will compare the observations with those made at the groundbased reference GNSS station available at our research facility.

Sharjah-Sat-1 is the first CubeSat to be designed and integrated at the Sharjah Academy for Astronomy, Space Sciences and Technology (SAASST), a research institute under the University of Sharjah (UoS) in the United Arab Emirates, with an active collaboration with Istanbul Technical University and Sabanci University in Turkey. The mission is due to launch in December 2022. Sharjah-Sat-1 hosts a primary payload of an improved X-Ray Detector (iXRD). The iXRD utilizes a CdZnTe crystal as an active detector to detect and measure bright and hard X-Ray sources and a tungsten collimator. The instrument’s detection range is 20-200 KeV at a spectral resolution of 6 Kev at 60 KeV [1]. The detector will be able to measure the flux of ionizing x-ray around the south Atlantic anomaly, the data of which will be shared to provide space situational awareness for other satellite operators to perform any preventative maneuvers to protect their space assets. This paper will discuss how the improved X-Ray Detector (iXRD) on-board the Sharjah-Sat-1 CubeSat can be utilized to provide space situational awareness.
