Additionally:

> Note that Cosmos 2546 was launched in May 2020 and so cannot be responsible for the interference events that occurred in 2019. Moreover, Cosmos 2546 was not over Europe during some interference events after May 2020. But during all events on the 75 days shown in Table 1 there was at least one EKS satellite above a 35∘ elevation angle with respect to every reference station that observed the interference. Thus, it is highly probable that the EKS constellation is collectively responsible for the wide-area transient GNSS interference events noted since 2019.
