Abstract
The IEC 61108-7 standard focuses on the minimum performance required by shipborne receivers using satellite-based augmentation system (SBAS) L1 signals to be compliant with the performance specified in IMO Resolution A.1046(27). Apart from the minimum performance requirements, the standard specifies the testing methods and a full set of scenarios with their pass/fail criteria. To verify the feasibility of the tests defined in the standard, a comprehensive test campaign was carried out in a joint effort by the European Satellite Services Provider (ESSP) and the European Commission’s Joint Research Centre (JRC) under the coordination of the European Union Agency for the Space Programme (EUSPA). This paper presents an assessment of the validity and appropriateness of the test scenarios and the minimum performance requirements specified in the IEC-61108-7 standard. To conduct the campaign, dedicated setups were designed and implemented at the JRC and ESSP laboratories, where live and simulated GPS+SBAS signals were used. For the analysis, all the test cases (TCs) described in the standard were implemented, and two commercial devices were tested. From the results, it emerged that all the TCs were properly designed and implemented, thereby confirming the feasibility of the tests defined in IEC 61108-7.
