Heading Versus Tilt Chart for Assessing HGA Occlusion and Flop Risk in MSL Operations

The Mars Science Laboratory (MSL) high-gain antenna (HGA) sits low on the deck, leaving the sky occluded in many directions by other parts of the rover. Each drive must end with the rover at a heading where the Earth will be unoccluded during the next HGA...

Rapid Forest Triage by Sub-Canopy Micro Air Vehicles

Today, tree distribution maps can only be generated manually in a very time-consuming process, and real-time microclimate mapping of a large 3D volume under tree canopy is not possible. A prototype small quadrotor unmanned aerial vehicle (UAV) system was developed that is able to maneuver in...

Ship Classification Using Gnostic Fields

There are many applications for Autonomous Seaborne Vessels (ASVs). The seaborne cargo shipping industry moves over 9 billion tons of cargo per year, is worth $375 billion, and is responsible for 90 percent of world trade. Autonomous cargo ships could reduce the operating expenses of cargo ships by 44%....

3D Motor for Multi-Axis Attitude Control on SmallSats

For improved performance-to-mass ratio, a reaction sphere is a 3D motor that could replace what would conventionally require at least three separate single-axis motors.

Preliminary data was recently provided for a reaction sphere prototype on NASA’s zero-gravity parabolic flight...
