Single-Antenna Low Earth Orbit Signal Simulator for Hardware in the Loop Testing. McDougal, S., Morgan, S., & Martin, S. In pages 2349–2361, September, 2022.
Paper doi abstract bibtex Simulation tools are vital to the engineering design process. They allow for changes and modifications to current test plans before production or implementation. With regard to global navigation satellite systems (GNSSs), such as the global positioning system (GPS), signal simulation tools help with the design of software defined receivers and allow for testing of error mitigation. With recent research featuring navigation with signals of opportunity and low Earth orbit (LEO) satellite constellations, a signal simulation tool is applicable here as well. In this paper a signal simulation tool for LEO satellite navigation is developed. This simulation tool is block-like to provide flexibility to the user which allows for fast testing of various signal types and constellations. The simulation in this paper focuses on two LEO constellations, Iridium and Orbcomm. To demonstrate the simulation tool, a navigation signal is designed for both constellations. Then, the broadcast of this signal is simulated. A receiver is designed to process the simulated signal, and a navigation solution is computed. This simulation tool shows effectiveness at simulating multiple LEO constellations and generates realistic signals that receivers can process.
