 7 elements array: cases considered in the navigation realistic scenario.

Case	Meaning
FRPA cosine-like	The radiation pattern of the user antenna is a fixed beam approximated by a 𝑐𝑜𝑠𝑖𝑛𝑒^𝑝 function (𝑝: integer). No interfering satellite is considered in the analysis.
FRPA simulated	The radiation pattern of the user antenna is a fixed beam (Figure 15) designed and simulated by electromagnetic commercial tool (i.e., “CST studio suite”). No interfering satellite is considered in the analysis.
FRPA cosine-like with IF	The radiation pattern of the user antenna is a fixed beam approximated by a 𝑐𝑜𝑠𝑖𝑛𝑒^𝑝 function (𝑝: integer). Interfering satellite is considered in the analysis.
FRPA simulated with IF	The radiation pattern of the user antenna is a fixed beam (Figure 15) designed and simulated by electromagnetic commercial tool. Interfering satellite is considered in the analysis.
CRPA	The radiation pattern of the user antenna is synthesised by MVDR algorithm (beam-forming) implemented by “MatLab” software tool. In other words, the antenna dynamically synthesizes null/s along direction of interferer/s. Interfering satellite is considered in the analysis.
