We discuss client-side CORBA scripts implemented in Tcl, Perl, and Python. These are all technologies that are either currently being used on testbeds at JPL or being evaluated for future use. Finally, a Python example demonstrating implementation of a simple CORBA server is presented.
This paper will describe how the SIM thermal control designers have addressed some of these very challenging requirements.
Planet detection around a bright star depends the resolution of the imaging system and the degree of light suppression of the star relative to the planet. We present a concept for a visible light Terrestrial Planet Finding (VTPF) mission. Its major feature is an imaging system for planet detection using a nulling interferometer behind a single aperture telescope. This configuration is capable of detecting earth-like planets with a 5m aperture using both imaging and spectroscopic imaging modes. We will describe the principles of the system, and show results of studies demonstrating its feasibility.
This work reports on the computation of the average phase of a beam over an optical element via discrete Fourier transform techniques.
One of the principal objectives of remote sensing is full carbon accounting in the worlds forests via biomass monitoring.
This paper describes the development of the self-gravity modeling tool used to predict and control the motion of one of the proof masses of the orbiting LISA gravitational wave detector.
This paper briefly describes the nanometer-class metrology system used in this testbed to estimate the length and orientation of the science baseline vector, which cannot be measured directly. The focus is on the mathematical inversion problem that results and its solution.
Very-long-baseline interferometric measurements of the positions of planetary orbiters/landers relative to nearby extra galactic radio sources provide information on the positions of the planets in the inertial reference frame described by the measured positions of the radio sources.
We describe a laboratory test of TDI with an unequal arm interferometer. The intent is to ascertain the performance limitations and proof-of-concept for 6 orders of magnitude frequency noise suppression.
