Parallax-Based Tracking of Moving Aerial Objects Using Commercial Satellite Imagery: Insights from the Galileo Project

To the point

Planet’s SuperDove satellites can spot moving aerial objects, including UAPs, by using parallax from time-staggered spectral bands to estimate speeds and altitudes (about 21,200–21,500 m) from balloons such as the Chinese spy balloon and one over Colombia, with some backgrounds like snow less useful than others, RAIC Labs tracing the balloon’s route, Avi Loeb and the Galileo Project highlighting motion as a possible sign of extraterrestrial origin, and Eric Keto and Wesley Andres Watters arguing this motion-based method could become a standard tracking tool.

How Commercial Satellites Could Track Spy Balloons and Other UFOs

Eric Keto and Wesley Andres Watters of Harvard's Galileo Project demonstrated that Planet's SuperDove satellite imagery can reveal moving aerial objects, including UAPs, by using time-staggered multispectral exposures to derive apparent velocities and infer altitudes around 21,200–21,500 meters for a Chinese balloon and a second balloon over Colombia, leveraging parallax between spectral bands as a tracking baseline; while backgrounds like snow in British Columbia were less useful, sites in Missouri and Colombia provided workable data, RAIC Labs with Planet traced the balloon’s route toward its origin near Hainan, Avi Loeb has argued that unusual motion could signal extraterrestrial origin, Keto and Watters frame motion-based signals as diagnostic tools, and the work has been posted to arXiv and submitted to the Journal of Astronomical Instrumentation, signaling that satellite-derived tracking could become a standard method for detecting anomalous aerial phenomena.
