Integrated and cost-effective simulation tool for GNSS space receiver algorithms development

AGGA-4 is a GNSS baseband signal processor for space applications, developed under ESA contract, currently being implemented. This paper presents the “GNSS Dynamics Simulator and AGGA-4 Test and Simulation Tool” (GSTST), being developed by DEIMOS Engenharia under ESA contract. The GSTST is an integrated simulation and testing tool for the design and realistic analysis and test of GNSS signal processing and navigation algorithms for AGGA-4-based GNSS receivers, which will allow AGGA-4-targeted software to be tested without the need for the AGGA-4 chip or complex and expensive hardware setups.
