The Satellite Pass Directly Overhead Is the One You Cannot Use

Pick a point on the ground and this tells you when ICEYE or Umbra will be in a position to put radar on it, how to aim a corner reflector when they do, and hands the whole thing to ATAK as a data package. It reads orbital elements from Celestrak by name, so nothing is pinned to a NORAD ID that can quietly start pointing at the wrong object.

Try the browser preview — no install. It pulls the orbital elements and does the propagation in your own browser, so where you look never reaches my server. The desktop tool adds the ATAK package, notifications, a menu-bar watcher and cross-checking against a commercial archive.
