The DICE satellites will collect data on variations in ionosphere plasma density that affect the performance of communications, surveillance, and navigation systems on earth and in space. The small, low-powered satellites measure 10 x 10 x 15 cm each, and require ultra-small, low-power components. The project is funded by a $1.2 million grant from the National Science Foundation.
The New Scale motion module is a miniature high-resolution positioning system with piezoelectric motor, integrated drive electronics and closed-loop control. Less than half the size and one-fourth the weight of comparable systems, it offers 0.5µm position resolution with many millimeters of travel. It operates on a 3.3V input and holds position with power off.
