LiDAR for Robust Exoatmospheric Positioning
Abstract
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 constellation of orbital reflectors. We discuss the precision of the method, the power requirements, the advantages of such a method over existing GPS/GNSS systems, and potential applications.
