How SpaceVPX
is Influencing the
Design of Next Generation
Spacecraft Avionics
O
20
ver the last decade, a government-industry effort
to advance the use of modern computer processors
and networks in spacecraft avionics systems
has quietly been making its own gains in industry
adoption and a re-thinking of the way next generation
spacecraft electronic systems could be designed in a less
costly and more interoperable way.
Spacecraft avionics systems are all of the electronic
instruments, components, computers and subsystems that
control primary spaceflight flight and data communications
functionality.
Historically, spacecraft OEMs, systems integrators and
designers have relied on avionics systems and embedded computer
processing architectures that are singularly developed,
power hungry and often sharing data over legacy networks
between computers that use older processor technology.
Over the last decade, the advancement and revision of
the SpaceVPX (VITA 78) standard has been the driving
force behind removing bandwidth as a constraint for
spacecraft avionics systems and establishing an ecosystem
of suppliers and designers that develop systems based on
re-usable card-sized processing modules.
What is SpaceVPX?
SpaceVPX is an embedded computing standard based
on bridging the VMEBus International Trade Association
(VITA) OpenVPX standards to space applications.
OpenVPX is a set of embedded computing system standards
that are widely used in safety critical aerospace
and defense platforms such as vehicles and weapons. Its
primary purpose is to provide a standardized architecture
for the electrical, physical and mechanical specifications,
form factors and characteristics of embedded
computing modules, backplanes and chassis.
The SpaceVPX standard was first established in 2015,
when it was officially recognized by the American National
Standards Institute (ANSI) under VITA Standards Organization
(VSO) guidance as ANSI/VITA 78.00-2015.
Patrick Collier, who currently works as a consultant
with Aspen Consulting Group and Michael Walmsley, a
Product Manager at TE Connectivity, two of the original
architects of the SpaceVPX standard, previously explained
the development of SpaceVPX from its origins in their
August 2022 SpaceNews article, " SpaceVPX (VITA 78) and
the World of Interconnect. "
