AbstractWe describe in details the algorithms used in modelling the self-shadowing between spacecraft components, which appears when computing the surface forces as precisely as possible and especially when moving parts are involved. This becomes necessary in planetary geodesy inverse problems...
AbstractThe current work focuses on vibration and modal analysis of KufaSat structure using ANSYS 16 program. Three types of Aluminum alloys (5052-H32, 6061-T6 and 7075-T6) were selected for investigation of the structure under design loads. Finite element analysis (FEA) in design static load of...
AbstractGlobal Positioning System (GPS) technology is ideally suited for inshore and offshore positioning because of its high accuracy and the short observation time required for a position fix. Precise point positioning (PPP) is a technique used for position computation with a high accuracy...
AbstractTri-axial gyroscopes used to be the only instrument used to measure the angular increments of airplanes. However, because there were no reference devices, drift and accumulation errors affected the accuracy of the estimated attitude. In this paper, we propose a novel method for measuring...
