Technological verification of the satellite module for precise determination of the position of satellites in orbit

Abstract

Today, nanosatellite constellations are increasingly used in various missions. Given the complexity of these missions, more precise positioning and maneuvering is required for all constellation components. Recently positioning solutions are based on Global Navigation Satellite Systems (GNSS), such as the Global Positioning System (GPS), the European GALILEO system, which have complied the stringent requirements of satellite constellations. This paper proposes the development of a low-cost, COTS, point-precise positioning (PPP), multi-constellation, multi-frequency GNSS satellite receiver module for technology verification, enabling positioning accuracy of the order of cm on low earth orbits (LEO). In addition, this satellite module will integrate orbit determination algorithms and positioning modes, which would provide low power consumption, an accurate orbit propagator and an embedded artificial neural network (ANN).
