Innovation: Interfacing Clearly: A New Approach to the Design and Development …
Systems engineering is an interdisciplinary field of engineering focusing on the design and management of complex engineering projects. According to the International Council on … GNSS interoperability concerns the integration of different GNSS with …
Summary: In this article, we present the results of ongoing research on the use of a modeling language, namely Interface Communication Modeling Language (ICML), for signal-in-space (SIS) interface specification of global navigation satellite systems (GNSS). … In particular, we outline how a model-based SIS interface specification can support the identification of solutions to two key issues: GNSS interoperability and the design of GNSS receivers, particularly Galileo receivers.
… linking the SIS interface specification to the design schemas of GNSS receivers — particularly Galileo ones — for tracing the interface elements onto the receiver functional and physical schema, thereby supporting the reuse and adaptation of existing HW and SW solutions;
…Scenario 3 is a development of Scenario 1 and Scenario 2, in which the physical schema definition and the physical components identification (HW and SW) may further exploit the ICML-based approach for supporting the reuse of existing GPS components.
…A GNSS receiver functional schema has been derived from A Software-Defined GPS and Galileo Receiver: A Single-Frequency Approach (see Further Reading) and its equivalent SysML internal block diagram (IBD) is shown in FIGURE 6.
