FOR IMMEDIATE RELEASE
U.S. Air Force Awards Contract to Stottler Henke to Develop an
Intelligent Scheduling System for the Satellite Control Network
Advanced artificial intelligence software will generate optimized schedules automatically
to ensure reliable operation of U.S. satellites
SAN MATEO, CA, March 30, 2009 — Stottler Henke Associates, Inc. today announced the
award of a contract with the U.S. Air Force to develop an advanced decision support tool to
schedule space-to-ground communications that monitor and control U.S. Government satellites.
The system incorporates Stottler Henke’s proprietary Aurora™ software that uses artificial
intelligence techniques to generate optimized solutions to complex scheduling problems.
The U.S. government’s satellite control network is comprised of more than a dozen ground
stations and hundreds of satellites that fly in geosynchronous, highly-elliptical, or low-earth
orbits. These satellites support a wide variety of military and non-military missions, and their
continuous operation is vital for national security.
Satellites must periodically exchange health and status data and commands with ground
stations to ensure that they maintain their orbits and operate correctly. Currently, the Air Force
relies on teams of planners to schedule these satellite-to-ground communication passes. When
a ground station problem occurs, communication passes involving the faulty ground station
must be quickly rescheduled and reassigned to new ground stations to meet mission deadlines.
However, scheduling is complex because the times when communications can take place
depend upon each satellite’s unique orbit and the type and location of each ground station.
Communication time windows of low earth orbit satellites can last just ten or fifteen minutes as
they quickly fly in and out of view of a ground station.
Under this contract, Stottler Henke is designing and prototyping an advanced decision support
system that will generate optimized schedules for communication passes that satisfy these
complex constraints. It will incorporate its proven Aurora scheduling engine to generate high-
quality schedules.
“Organizations usually develop expensive custom software systems to solve resource allocation
problems with unique and complex constraints”, says Dick Stottler, president of Stottler Henke.
“By leveraging Aurora technology, we can quickly develop an extremely capable scheduling
system that generates optimized solutions automatically.” continues Stottler.
Aurora is a sophisticated scheduling system that combines a variety of scheduling techniques,
intelligent scheduling conflict resolution, and decision support to generate highly efficient
solutions to complex problems. The software’s customizable scheduling algorithms take into
account resource requirements, complex constraints, and pertinent domain knowledge.
Aurora’s built-in capabilities and extensibility enable it to significantly outperform other
scheduling systems that use generic heuristics to assign resources to tasks. The
Boeing Company uses Aurora to manage the process of building the Boeing
787 Dreamliner™ commercial airliner,
and NASA uses Aurora at Kennedy Space Center to
schedule
International Space Station payload
and
Shuttle processing activities.
The United Space Alliance (USA) incorporated Aurora into Temporis,
designed to schedule flight activities on board NASA’s next-
generation manned spacecraft.
Aurora was featured in NASA’s Hallmarks of Success video
series that showcases successful spin-off technologies.
Founded in 1988, Stottler Henke Associates, Inc. applies artificial intelligence and other
advanced software technologies to solve problems that defy solution using traditional
approaches. The company delivers intelligent software solutions for education and training,
planning and scheduling, knowledge management and discovery, decision support, and software
development.
In 2006, Stottler Henke was the subject of a NASA
"Hallmarks of Success"
video profile
for its work developing and later commercializing
advanced planning and training software systems.
Stottler Henke received a
2004 "Brandon Hall Excellence
in Learning" award
for innovative technology.
Stottler Henke was named one of the "top 100" companies making a significant impact on the military
training industry by Military Training Technology magazine, and in 2005 received a Blue
Ribbon recognizing it as a company that leads the industry in innovation.
