Figure 4-18: Position estimations delivered by Demonstrator 2, May 2022 
The next chapters present the results for the characterisation of the interference situation in otheı 
months of the measurement campaign, I.e. from June 2022 to July 2023. 
4.1.2. Interference situation in June 2022 
The RFI detection metric and the number of satellites in track and used for PVT are presented 
below in Figure 4-19 and Figure 4-20. A closer look is taken in Figure 4-21 on the place with a 
noticeable increase of the RFI detection metric on June 13

Figure 4-19: RFI detection metric, June 2022 
As can be observed in Figure 4-21, the presence of the radio frequency interference, which can be 
detected by using the array-based RFI detection metric, does not produced any observable effect 
on the receiver metrics such as C/NO or the number of received and used GNSS satellites. Also, the 
oosition estimation delivered by the Demonstrator 2, that is shown in Figure 4-22, is apparently 
10rmal with no outliers.
