PSNDL: Precision Navigation Without GPS

A next-generation navigation and sensing system for space, Psionic’s Space Navigation Doppler Lidar (PSNDL) enables spacecraft to map surfaces, detect hazards, and navigate autonomously—even in GPS-denied environments like the Moon, Mars, or deep space. It provides precise, real-time data to ensure safe landings, rover mobility, and mission success.

How PSNDL is Different:

  • Coherent laser system measures both distance and speed
  • Provides continuous, high‑precision measurements in the most adverse environments
  • Uses doppler effect methods to reduce uncertainty in velocity and altitude during descent
  • Multi-channel integration to provide body-frame velocity vector position and attitude relative to the target
  • Useful for both landing and rendezvous / docking / proximity operations
