Small-Body Dynamics Toolkit Version 5.0

The Small-Body Dynamics Toolkit (SBDT) v5.0 is a collection of primitive-body-specific trajectory design and analysis tools written in MATLAB®. The SBDT gives the user the capabilities to propagate, analyze, and visualize spacecraft trajectories and the dynamical environment near realistic asteroid,...

Briefs: Test & Measurement

An innovative optical sensing and tracking system was designed to detect, track, and determine object distance and direction in a wide, full, solid angle (160 × 160°) with an extremely high...

Six-Degree-of-Freedom Control With Only Eight Thrusters

Typical spacecraft thruster configurations are often unable to provide full six-degree-of-freedom control and may have unwanted interaction between their attitude control and trajectory control functions, have undesirably high instantaneous electrical power demands, and use more thrusters...

Application Briefs: Robotics, Automation & Control

Unlike industrial robots for manufacturing, service robots come with their own specification requirements aimed specifically at the end user, and the most discriminating user at...

Briefs: Electronics & Computers

Designing automotive electronics presents numerous technical challenges, including the need to protect against electrical hazards. The three major sources of electrical hazards...

Update on PISCES

An updated version of the Platform Independent Software Components for the Exploration of Space (PISCES) software library is available. A previous version was reported in “Library for Developing Spacecraft-Mission-Planning Software” (MSC-22983), NASA Tech Briefs, Vol. 25, No. 7 (July 2001), page 52. To recapitulate: This...

Briefs: Electronics & Computers

Vector modulators are used to impose baseband modulation on RF signals, but non- ideal behavior limits the overall performance. The non-ideal behavior of the vector modulator is...

Briefs: Electronics & Computers

An architecture for autonomous operation of an aerobot (i.e., a robotic blimp) to be used in scientific exploration of planets and moons in the Solar system with an atmosphere (such as Titan and Venus) is...
