systems

Commercial off-the-shelf (COTS) computing systems afford end users access to the most

advanced technology at mass-market prices. Platform time-to-market is dramatically

reduced along with technical risk. Because the development has already been performed

up-front for these standard systems, the non-recurring engineering expense has been

greatly reduced, if not eliminated. Emplacing COTS systems in the harsh environments

typically encountered in military and aerospace applications will usually require special-

ized packaging to achieve certification for the lifecycle demanded by the end user.

GE Intelligent Platforms excels at the design of COTS systems

with levels of ruggedization ranging from benign to being capable

of withstanding harsh military and aerospace conditions such

as thermal extremes, vibration, shock, sand and dust, salt fog,

humidity, acceleration, electromagnetic interference, and nuclear/

electromagnetic pulse, as well as human intrusion and compro-

mise. We provide a full range of COTS system packaging services,

from creation of specifications to rigorous qualification testing.

GE has developed five levels of circuit board ruggedization, each

providing the optimal balance of cost, performance and reliability.

Our engineers first recommend a COTS board based on the performance requirements of the speci-

fication, then select the chassis and racks based on the type of cooling (forced air, convection, or

conduction) required, as well as estimates of power dissipation, board/slot count, and user environ-

ment. After engineering analysis and simulation assures performance capabilities, prototype and

qualification testing is conducted to certify that the system will indeed function in the intended

environment. All rugged COTS equipment is tested to environmental test specifications that have

the widest applicability. MIL-STD-810 has emerged as an important environmental test standard

for rugged COTS systems because of its broad applicability to rotary/fixed-wing aircraft as well as

ground/amphibious vehicles, but some unique rugged systems specifications require specialized

design, analysis and testing to certify the required level of performance in a given environment.

GE has developed a comprehensive process for the develop-

ment of rugged systems. Our ISO 9000/AS9100 certified design

and testing process is exhaustive, but our extensive design data

and experience base greatly reduces development time while

assuring low program risk for the contractor.

COTS products making up a rugged system can include single

board computers, analog and digital I/O boards, Ethernet

switches, solid state drives, power supplies, and chassis. Boards,

especially I/O boards, can be modified to meet program speci-

fications, and customer-designed or third-party products can

also be included in the system specification. Raised lids and

media adapters can be included in the chassis design to accom-

modate the routing of fiber optics and cabling, as can external

doghouses for external removable memory.
