available at a so-called " big box store, " to
rugged systems designed for use in industrial
environments, and at the far end
of the spectrum from commercial products,
those fully rugged solutions designed
from the ground up specifically to
operate in harsh military environments.
The VPX (VITA 65) profile provides a
robust and popular design for open standard-based,
rugged electronics for defense
applications. The backplane-based
systems that use these removable modules
(also known as plug-in cards or PICs)
are housed in chassis that meet a range
of environmental conditions addressed
by MIL-STD-810. The VPX standard is a
foundational element of Modular Open
Systems Approach (MOSA)-supporting
standards such as the Army's CMOSS
(C5ISR/EW Modular Open Suite of Standards)
and the Sensor Open Systems Architecture
(SOSA) technical standard currently
being defined.
Leading military COTS electronics
vendors actively contribute to the definition
and advancement of the open
standards included in CMOSS and those
being defined by the SOSA Consortium.
In addition, many of these vendors participate
in the VITA Standards Organization
(VSO) that oversees the definition
of the OpenVPX, PMC, XMC, and FMC
The small form factor PacStar 464 Secure Wi-Fi Access Point module is an example of a rugged module
ideal for use at the edge of the tactical battlefield.
form factor standards called out by the
CMOSS and SOSA technical standards.
Electronic systems designed specifically
for defense applications also come
in a range of ruggedization levels, depending
on the type of platform and
the environment in which they are intended
to perform. For example, a mission
computer deployed on a helicopter,
where the ability to operate
optimally when exposed to intense vibration
conditions, will necessarily be
more rugged than a mission computer
with the
same compute performance intended
for use in a mobile ground command
center.
Another issue is size, weight, and
power (SWaP). Theoretically, while
commercial equipment could be enclosed
in a radiation-shielded, sealed,
environmentally controlled case with
shock and vibration isolation, this approach
would be impractical and prohibitive
for ground vehicles
from a SWaP perspective.
