Spaceborn Computer MBC186/3081 Series
Description
High Reliability Embedded MBC186/3081 Computer is designed to control
space vehicle onboard equipment. The computer can be furnished with both
Intel 80C186 or IDT R3081 microprocessors and has MilStd-1553 interface
for communication with onboard systems, two high-speed UART port for communication
with other similar computers and the UART ports for testing purposes.
Peripheral modules
For integration with onboard equipment the Computer is supplied with up
to 16 peripheral modules with customized interfaces. At present 10 types
of the peripheral modules have been designed. These modules are provided
with various analog and digital I/O ports.
Sliced construction
The computer has a sliced (modular) design and is provided with minimum
weight and size for any specific configuration. The redundant system can
be designed using the majority voting scheme.
The principle of sliced design is simple. Each individual slice is designed
with its own structural frame, rather than inserted into a chassis backplane.
When stacked one on another and closed with a top and bottom cover, these
slices create a shielded housing. The construction of the computer's slice
is provided with conductive cooling of the components and their high reliable
operation.
Spaceborn computer seriaes are designed in cooperation with RC ARGON,
RSC Energia and RC Rubikon-Innovacia
