Solar array drive assembly

Developed for small spacecraft requiring solar array pointing and power transfer in approximately the 1.5 kW range, this Solar Array Drive Assembly (SADA) has been qualified and life tested for an upcoming mission for Momentus Space. Utilizing vacuum and temperature capable commercial components, it is the first flight-capable SADA that offers traditional space performance and reliability at a price supportive of typical small spacecraft budgets. The unit incorporates a large central hole that currently houses a twist harness section, hard stops, and position indication at the range of motion extremes and home position. Baseline performance is shown below. A structurally-enhanced unit is currently in development with delivery scheduled later this year and the basic configuration can be easily and rapidly adapted for your specific mission requirements.
