2.2.3.2. Determine average values according to (6) obtained for all tested eCall samples.

2.2.3.3. Tests results are considered satisfactory if horizontal position errors obtained with all eCall samples do not exceed 15 metres under open sky conditions at confidence level 0,95 probability.

2.2.4. Movement in shadow areas, areas of intermittent reception of navigation signals and urban canyons.

2.2.4.1. Repeat test procedures described in section 2.2.3 for simulation script for movement in shadow areas and areas of intermittent reception of navigation signals (given in Table 4) with an urban canyon signal pattern described in Figure 3.
