ITU-R S.1857 SPANISH-2010 Methodologies to estimate the off-axis e.i.r.p. density levels and to assess the interference towards adjacent satellites resulting from pointing errors of vehicle-mounted earth stations in the 14 GHz frequency band
This Recommendation presents the general antenna pointing error characteristics of vehicle-mounted earth stations with active antenna tracking systems and provides a method to estimate the statistics of off-axis e.i.r.p. variations due to pointing errors. Furthermore, it provides a methodology to assess the potential interference towards adjacent satellites operating in the GSO, FSS systems.
