Conceptual Design of a Navigation CubeSat for Local Positioning System (Iran Region), Based on COTS Approach

The main purpose of this paper is to design a navigation CubeSat constellation for local positioning system (LPS) that provides the postiong of Iran, based on COTS approach. To this end, the initial processing of subsystems' information was carried out using statistical processing of CubeSats with the same mission. According to the resultant data, common specifications of different subsystems (structure, electric power, attitude determination and control, thermal control, and communication), including required mass, power, volume and price were determined. Furthemore, the payload design was performed based on the specific mission, design matrix requirements, etc. by utilizing similar subsystem class catalogues (called COTS). Also, local positioning and coverage of the satellite constellation for the Iran was analyzed and simulated from the availabile datd in the Satellite Tool Kit (STK). Finally, the CubeSats constellation with specified subsystem (based on COTS approach) has been suggested for the acceptable coverage percentage to determine the local positioning in Iran. ‌‌
