Flightspeed Integral Image Analysis Toolkit
The Flightspeed Integral Image
Analysis Toolkit (FIIAT) is a C library
that provides image analysis functions in
a single, portable package. It provides
basic low-level filtering, texture analysis,
and subwindow descriptor for applications
dealing with image interpretation
and object recognition. Designed with
spaceflight in mind, it addresses:

Work Coordination Engine
The Work Coordination Engine
(WCE) is a Java application integrated
into the Service Management Database(SMDB), which coordinates the dispatching
and monitoring of a work
order system. WCE de-queues work
orders from SMDB and orchestrates the
dispatching of work to a registered set of
software worker applications distributed
over a ...

Multi-Mission Automated Task Invocation Subsystem
Multi-Mission Automated Task
Invocation Subsystem (MATIS) is software
that establishes a distributed dataprocessing
framework for automated
generation of instrument data products
from a spacecraft mission. Each mission
may set up a set of MATIS servers for
processing its data products. MATIS
embodies lessons learned in experience
with prior instrument-data-product-generation
software.

Autonomously Calibrating a Quadrupole Mass Spectrometer
A computer program autonomously
manages the calibration of a quadrupole
ion mass spectrometer intended
for use in monitoring concentrations and changes in concentrations
of organic chemicals in the cabin air of the
International Space Station. The instrument parameters calibrated
include the voltage on a channel electron multiplier,
a discriminator threshold, ...

Determining Spacecraft Reaction Wheel Friction Parameters
Software was developed to characterize the drag in each of
the Cassini spacecraft’s Reaction Wheel Assemblies (RWAs) to
determine the RWA friction parameters. This tool measures
the drag torque of RWAs for not only the high spin rates (>250
RPM), but also the low spin rates (coast-down regions.
