Psionic Space Applications

Psionic Doppler Lidar delivers superior range and relative velocity measurements over long distances in space to provide operational assurance and reduce mission risk. Smaller and lighter than competing heritage technology offerings, Psionic Doppler Lidar can also reduce fuel, power and volume requirements providing more room for payloads.

Psionic Navigation Doppler Lidar was developed by NASA for use in autonomous space vehicles. Today we work with leading public and private space entities to incorporate this technology into their missions.

Navigation Technology for Landing

Building upon NASA’s technology and patents (licensed exclusively to Psionic), Psionic Navigation Doppler Lidar is the next-level technology and provides extreme performance. Robustly tested, once integrated into your guidance system Psionic can provide the mission assurance you require.

Navigation for Rendezvous & Proximity Operations

The current procedures for docking in space may seem archaic and in contrast to the image of approaching spacecraft—inching towards each other over the course of a few days, and then when close “grabbing” the other spacecraft with a giant robotic arm.

Archaic in conception perhaps but practical, with the spacecraft traveling at 28,000 km/h they are immensely dangerous. Yet with Psionic Navigation Doppler Lidar mating spacecraft can instantaneously obtain range and vector velocity information with cm-level accuracy.

Psionic Navigation Doppler Lidar can make the docking phase of your operation last a few hours rather than days and—more importantly—increase operational assurance in the process.

Precision Targeting

Today there are nearly 129 million pieces of debris in various orbits around the earth and this number is growing. According to European Space Agency estimates approximately 34,000 are at least 4 inches wide and since they are moving fast—17,500 mph in low-Earth orbit, for example—that even the smallest of them could massively damage a satellite.

Several new ventures utilizing new technologies and new business models are poised to attempt dealing with this problem. The first step in the challenge is identifying then capturing extremely dangerous fast-moving debris in the vastness of orbit.  Psionic technology can provide the precision situational awareness and targeting to enable the destruction individual pieces of debris without affecting nearby satellites

Astrobotic Selects Navigation Doppler Lidar from Psionic for Mission to Deliver VIPER to the Lunar South Pole [Astrobotic]

Navigation Doppler Lidar chosen for high accuracy and NASA heritage for 2023 CLPS mission to search for water on the Moon


Astrobotic today announced they have selected Navigation Doppler Lidar (NDL) from Psionic for their mission in late 2023 to deliver NASA’s Volatiles Investigating Polar Exploration Rover (VIPER) to the South Pole of the Moon. The NDL serves as a critical sensor element as part of the Griffin Lander’s Guidance, Navigation, and Control (GN&C) system to ensure a safe, precise landing. In June 2020, NASA awarded a $199.5 million contract to Astrobotic under its Commercial Lunar Payload Services (CLPS) initiative.

Psionic NDL test with with Masten Space Systems | September 10, 2020

Lander Simulation Testing Helps Advance NASA Navigation Spinoff

A navigation doppler lidar (NDL) technology originally developed by NASA was demonstrated on a flight test on September 10 with support from the Flight Opportunities Program, part of NASA’s Space Technology Mission Directorate. With roots at NASA’s Langley Research Center in Hampton, Virginia, the technology was licensed in 2016 by Psionic for both terrestrial and space applications, and both the company and Langley continue to evolve and advance the innovation for upcoming lunar missions.

On the recent flight in Mojave, California, Masten Space Systems flew Psionic’s NDL payload on a vertical takeoff vertical landing (VTVL) system called Xodiac, which simulates some of the maneuvers of a lunar lander. Designed for precision landing in a very tightly defined area—often called the landing ellipse—the NDL transmits laser beams to the ground that bounce back to a sensor, providing information about the lander’s velocity and distance relative to the ground.

Psionic’s View

“Psionic Navigation Doppler Lidar (PNDL) helps ensure safe, precise lunar landings and will be an important part of upcoming unmanned and manned flights. The Flight Opportunities program enabled us to advance the technical readiness level of PNDL with a representative lunar landing trajectory aboard the Masten Xodiac free flying rocket. During the flight, we acquired valuable data to advance the robustness of the sensor-to-navigation computer interfaces, setting the stage for future missions, and ultimately for Artemis’s manned mission to the moon.”
