LiDAR for Robust Exoatmospheric Positioning We present an active method for robust exoatmospheric positioning using space-based intensity modulated direct detection (IMDD) LiDAR with a spacecraft-based transmitter and receiver and a constellati...

New preprint out this week! I describe how you might build an un-jammable, un-spoofable alternative to GPS! 🧪🚀
