  10. ARISS meeting ESTEC 2014HAM Video The effects of the off-Nadir orientation of on-board ARISS-41 and ARISS-43 antennas • Conclusions • Off-Nadir mountingincreases link duration • From thispoint of view the 13° (#41 TBC) is the best • 13° offset antenna allows4’:31’’ @ 2.0 MSym/s and 40° pass, using a HAMTV standard station. i.e. 1.2 m, G/T=2.0 dB(1/K) • 13° offset antenna allows5’:31’’ @ 1.3 MSym/s and 40° pass, using a HAMTV standard station. i.e. 1.2 m, G/T=2.0 dB(1/K) • Higherpassesallowslongerduration, but impose strongerconstrain on tracking (greater Az. Speed). A 64° pass allows 5’:03’’ and 5’:52’’ respectively. ARISS International Delegates Meeting, April 3 - 5, 2014 – ESA ESTEC
