Final Report of BeJamDetect Project
-igure 4-22: Position estimations delivered by Demonstrator 2, 13-June 2022
Although no interference effects on the GNSS array receiver of the Demonstrator 2 can be
observed, the time evolution of the RFI detection metric in Figure 4-19 clearly shows that there are
time periods with very quiet interference situation (marked by green boxes in Figure 4-19) and
other periods with some interference present (marked by red boxes). The time periods with an
‚ncreased interference level often correspond to the time when the ship was underway, while the
quiet periods often occur when the ship stayed in a harbor.
4.1.3. Interference situation in July 2022
The RFI detection metric, the number of used satellites as well as the mean C/NO value are presented
oelow In Figure 4-23, Figure 4-24 and Figure 4-25, correspondingly. The time periods with
‚ncreased interference activity are marked in Figure 4-23 with red boxes.
