Abstract

Capturing Earth imagery from low-Earth orbit causes blur from the spacecraft’s orbital motion. Planet’s high resolution SkySat satellites utilize an Optical Image Stabilization (OIS) system to reduce motion blur by mechanical oscillation of the payload assembly. Automated on-orbit procedures and analyses are used for calibration and validation of the system across a fleet of 19 satellites. OIS actuation settings are configured for each image capture through automated optimization procedures. The benefit of the OIS system is demonstrated by an increased collection ground scan rate with no degradation to image quality, thereby improving fleet production capacity of the SkySat constellation.
