\tDesign and prototype a lightweight, precision-deployable mast for the Ka-band Radar Interferometer (KaRIn) antennas in the Surface Water and Ocean Topography (SWOT) mission.
\tPerformance goals are:
\tAzimuth pointing deployment precision: < 0.11°
\tElevation stability: < 16 milli-arcsec
\tFirst mode frequency: > 10 Hz
\tTechnologies including a precision deployable mast containing a multi-joint cable driven precision latch mechanism and a pointing adjustment mechanism.
