During the early stages of flight, Asterius will maintain a HGA-to-Sun
attitude for thermal control. During these periods, the LGA, with its
wider beamwidth, will handle communication. The HGA can gimbal 80
,
meaning that it can be used while traveling to Jupiter. However, the
data rate during cruise is not high enough to require the HGA, and
using the HGA necessitates extra pointing accuracy. Therefore, it is
not used during early cruise. However, it is available for use if it
is needed for some reason.
