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.

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.

Navigation Technology for Landing

When the Apollo missions landed on the moon the Eagle carried three radars to assist a manual landing in the Sea of Tranquility, a large flat area on the moon thousands of square kilometers in size. Today’s lunar missions demand precision landing from orbit in a 100 square meter target and autonomously, without the use of radar.

Originally developed by NASA, Psionic Navigation Doppler Lidar provides extreme performance equal to the demands of the lunar missions of today and tomorrow. 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
