Abstract
In This paper, a domestic regional and independent satellite navigation system, known as "IRANSS" has been designed and analyzed to cover user needs in the Middle East Region. The Space Segment of this constellation is composed of nine satellites in four orbits, in such a way three satellites have been considered in one GEO orbit [1] and two satellites are considered in each of three IGSO orbits [2]. Two main Tracking and Control Ground Stations and twenty wide area reference stations, assigned only for augmentation, form the Ground Segment. The focus of this research is on space segment and specially design a navigation constellation and satellites’ system design, and evaluation of the performance of the navigation system in combination with other satellite-based navigation systems, since Augmentation Systems prepare correction signals for a specific Navigation System by ground segment. STK is the main software used to design and analyze the performance of the system by DOP as a reference for Ranging Errors based on Constellation Geometry. All of design parameters are computed in a way to minimize GDOP with four satellites. The parameters of navigation accuracy have been compared with other active GNSS [3] constellations to evaluate error in the designed system. Analysis results express that the geometric accuracy of the designed system is solely 16 meters in 95% of a day in all points of the desired area and would be improved to 14 and 12.5 meters in the case of combination with BeiDou and GPS, respectively
