As the number of SATCOM terminals and users increase, GateHouse Telecom expects that the quality and maturity of these terminals will be significant competitive factors in the satellite market for years to come, stressing the importance of state-of-the art test methods and tools.
GateHouse Telecom has now teamed up with the Danish university Aalborg University and its Centre of Embedded Software Systems (CISS) which has many years of research and project experience with model-based testing of embedded systems.
With model-based testing, you model the behavior of the unit or system under test and autogenerate test scripts using a test generation tool. This approach has a number of advantages compared to traditional scenario-based test development, e.g., increased test coverage and lower maintenance effort for test suites.
GateHouse Telecom and Aalborg University initiated a research project on model-based testing in September 2018. The purpose was to investigate how model-based testing can be used to improve testing of Inmarsat’s BGAN SATCOM terminals. GateHouse Telecom is currently finalizing the company’s own assessment on model-based testing including how the test method can be used to generate test scripts that can work together with GateHouse’s BGAN Network Emulator technology.
Senior Project Manager at GateHouse Telecom, Søren Rønnest, said that at GateHouse, the company has a long term relation with Aalborg University, both on the company and personal level, as most of our engineers graduated from the university. For the firm, it was an obvious decision to launch a partnership to tap in to the university’s and, specifically, the Centre of Embedded Software Systems’ huge research and project experience in testing embedded software and model-based testing.
Associate Professor at Aalborg University, Brian Nielsen, added that at CISS, all want to collaborate with Gatehouse to share the latest research on methods and tools for model-based testing of embedded systems with the industry. At the same time, CISS is able to evaluate the results in advanced, real-life applications, such as SATCOM terminals and test equipment, and get feedback for further research and development.
