Final Report of BeJamDetect Project
Also, the time behaviour of the number of satellites tracked and used for PVT solution presented
in Figure 4-22 does not deliver any indications of strong interference effect. The outliers in the
number of satellites used for PVT are due to receiver-internal reasons —- seldom interruptions of the
time synchronisation of receiver clocks, which leaded to missed range observations in the next
single PVT epoch.
