Introduction
This technical document MARESS D2.2 has been prepared by European Satellite Services Provider
(ESSP) in the scope of MARitime Receiver SBAS Standardization (MARESS) project to support
International Standard IEC 61108-7 for SBAS receiver equipment. The purpose of this document is to
present it in CEN/CENELEC JTC5/WG8 working group to support standardization process within
IEC technical committee 80: Maritime navigation and radiocommunication equipment and systems.
Note at the time of the Publication: The outcome of this report has been already considered in the
development of the IEC 61108-7 standard. This implies that these results are obsolete since in the
current version of the IEC 61108-7 some requirements and tests have been updated.

4 Test scenarios
4.1 General
The test scenarios implemented in MARESS project have been based on the MARESS deliverable D2.1
Methods of testing and required results [1].
In this Clause, all the tests performed are listed including the respective configuration used. All the tests
have been prepared to process GPS L1 and SBAS L1.
The following information can be found for each of the tests executed:
• start date: indicate the start date of the scenario under test;
• duration: indicate the duration of the test;
• signal source: specify if the receiver was connected to real signals with a GNSS antenna in ESSP roof
(Madrid) or if the GNSS simulator has been used to generate the GNSS and SBAS signals;
• data source: indicate if real data has been used as input (GPS RINEX and EGNOS EMS files); or the
data has been automatically generated by the GNSS simulator (synthetic data);
• receiver position: provides the position of the receiver (real or simulated);
• specific configuration related with the objective of the test;
• outputs to be analysed: list of parameters to be retrieved from the receiver under test to check if the
test is passed/failed.

4.2 Test cases
4.2.1 Test case #1: static accuracy and availability
The objective of this test is to check the static accuracy and availability of the receiver when providing
SBAS PVT solution.
Table 1 provides specific information on the test characteristics and configuration:
Table 1 — Test case #1 — Scenario configuration
Start date N/A (variable)
Duration > 86 400 epochs
Signal source Real RF L1 Signal
Data source Real Data
Receiver position Lat = 40.472°
Lon = −3.452°
Height = 661,1 m
Specific configuration NMEA output rate: 1 Hz
Static receiver
Outputs Epoch
PVT solution mode
Position
All the outputs from the receivers are obtained through NMEA messages.
The start date is variable since it depends on when the receiver was connected to the antenna located in
the roof of ESSP premises in Madrid.
The results of this test are included in subclause 5.2.1.
4.2.2 Test case #2: static accuracy with angular movement
The objective of this test is to check the static accuracy and availability of the receiver providing SBAS
PVT solution when the antenna is performing an angular displacement of 22.5°, simulating roll, in a
period of 8 s during the duration of the test.
Table 2 provides specific information on the test characteristics and configuration.

Figure 1 shows a snapshot of the antenna movement configured in the GNSS simulator.

Errors have not been introduced in the GPS signals and so, the position error is expected to be more
accurate compared to a real scenario. However, the objective of the test is to check that the error is not
increased when the antenna performs the angular movements in comparison with a nominal static
scenario.
All the outputs from the receivers are obtained through NMEA messages.
The results of this test are included in subclause 5.2.2.

4.2.3.1 General
The objective of this test is to check the dynamic accuracy of the receiver providing SBAS PVT solution.
