Abstract

KhalifaSat is the third satellite launched by Mohammed Bin Rashid Space Centre (MBRSC) in October 29, 2018 from Japan's Tanegashima Space Center. It is the first satellite to be built in MBRSC’s clean room facility, and the first to be developed entirely by a team of highly qualified Emirati engineers. KhalifaSat is a remote sensing Earth observation satellite that provides a high resolution images with a spatial resolution of 0.7 m Panchromatic and four multispectral bands of 2.8 m. In addition to that, Calibration and Validation activities of KhalifaSat images, were performed by our team in MBRSC for the first time.
Prior to launch of KhalifaSat, the team went through a learning process on different Cal/Val activities. Some Calibration activities were performed such as non-uniformity correction, and generating initial sensor parameters. Following the successful launch of KhalifaSat, different calibration and validation activities were performed on KhalifaSat images. The aim of Cal/Val activities is to ensure that KhalifaSat fulfilled the standard requirements of image quality, and to further enhance the quality of KhalifaSat images. Different calibration activities include, dynamic range optimization, MTF compensation, radiometric calibration such as non-uniformity correction and validation, glitch compensation and geometric calibration such as band-to-band registration, geo-location accuracy error which is used to calibrate the interior orientation. 
In this session, the experience of the team during Cal/Val activities, the difficulties that were faced and how they were solved will be shared. In addition, the initial calibration and validation results will be presented.
